The Latin word imperator derives from the stem of the verb imperare, meaning 'to order, to command'. It was originally employed as a title roughly equivalent to commander under the Roman Republic. Later it became a part of the titulature of the Roman Emperors as part of their cognomen. The English word emperor derives from imperator via Old French Empereür. The Roman emperors themselves generally based their authority on multiple titles and positions, rather than preferring any single title. Nevertheless, imperator was used relatively consistently as an element of a Roman ruler's title throughout the principate (derived from princeps, from which prince in English is derived) and the dominate. In Latin, the feminine form of Imperator is imperatrix.

Imperatores in the ancient Roman Kingdom

When Rome was ruled by kings,[1] to be able to rule, the king had to be invested with the full regal authority and power. So, after the comitia curiata, held to elect the king, the king also had to be conferred the imperium.[2]

Imperatores in the Roman Republic

In Roman Republican literature and epigraphy, an imperator was a magistrate with imperium.[3] But also, mainly in the later Roman Republic and during the late Republican civil wars, imperator was the honorific title assumed by certain military commanders. After an especially great victory, an army's troops in the field would proclaim their commander imperator, an acclamation necessary for a general to apply to the Senate for a triumph. After being acclaimed imperator, the victorious general had a right to use the title after his name until the time of his triumph, where he would relinquish the title as well as his imperium.

Since a triumph was the goal of many politically ambitious Roman commanders, Roman Republican history is full of cases where legions were bribed to call their commander imperator. The title of imperator was given in 90 BC to Lucius Julius Caesar, in 84 BC to Gnaeus Pompeius Magnus, in 60 BC to Gaius Julius Caesar, relative of the previously mentioned Lucius Julius Caesar, in 45 BC again to Gaius Julius Caesar, in 44 BC to Marcus Iunius Brutus, and in 41 BC to Lucius Antonius (younger brother and ally of the more famous Marcus Antonius). In 15 AD Germanicus was also imperator during the empire (see below) of his adoptive father Tiberius.[4]

Imperator as an imperial title

After Augustus established the Roman Empire, the title imperator was generally restricted to the emperor, though in the early years of the empire it would occasionally be granted to a member of his family. As a permanent title, imperator was used as a praenomen by the Roman emperors and was taken on accession. After the reign of Tiberius, the act of being proclaimed imperator was transformed into the act of imperial accession. In fact, if a general was acclaimed by his troops as imperator, it would be tantamount to a declaration of rebellion against the ruling emperor. At first the term continued to be used in the Republican sense as a victory title but attached to the de facto monarch and head of state, rather than the actual military commander. The title followed the emperor's name along with the number of times he was acclaimed as such, for example IMP V ("imperator five times"). In time it became the title of the de facto monarch, pronounced upon (and synonymous with) their assumption.

As a title imperator was generally translated into Greek as autokrator ("one who rules himself," also sometimes used as a translation for Roman dictators.) This was necessarily imprecise as it lost the nuances of Latin political thought contrasting imperium with other forms of public authority. Nevertheless, this title (along with sebastos for augustus) was used in Greek-language texts for Roman emperors from the establishment of the empire.

In the east, the title continued to be used into the Byzantine period, though to a lesser, and much more ceremonial, extent. In most Byzantine writings, the Greek translation "Autokrator" is preferred, but "Imperator" makes an appearance in Constantine IV's mid 7th century mosaic in the Basilica of Sant'Apollinare in Classe, and on various 9th century lead seals.

Post-Roman use

After the Roman empire collapsed in the West in the 5th century, Latin continued to be used as the language of learning and diplomacy for some centuries. The Roman emperors of this period (referred to by modern historians as the Byzantine emperors) were referred to as imperatores in Latin texts, while the word basileus (king) was used in Greek.

After 800, the imperator was used (in conjunction with augustus) as a formal Latin title in succession by the Carolingian and German Holy Roman Emperors until 1806 and by the Austrian Emperors until 1918.

In medieval Spain, the title imperator was used under a variety of circumstances from the ninth century onwards, but its usage peaked, as a formal and practical title, between 1086 and 1157. It was primarily used by the Kings of León and Castile, but it also found currency in the Kingdom of Navarre and was employed by the Counts of Castile and at least one Duke of Galicia. It signalled at various points the king's equality with the Byzantine Emperor and Holy Roman Emperor, his rule by conquest or military superiority, his rule over several people groups ethnic or religious, and his claim to suzerainty over the other kings of the peninsula, both Christian and Muslim.

Beginning in 1077 Alfonso instituted the use of the style ego Adefonsus imperator totius Hispaniae ("I, Alfonso, emperor of all Spain") and its use soon became regular.[5] This title was used throughout the period 1079–81, which represents the peak of his imperial pretensions before his capture of the city of Toledo, ancient capital of the Visigoths. In 1080 he introduced the form ego Adefonsus Hispaniarum imperator ("I, Alfonso, emperor of the Spains"), which he used again in 1090. His most elaborate imperial title was ego Adefonsus imperator totius Castelle et Toleto necnon et Nazare seu Alave ("I, Alfonso, emperor of all Castile and of Toledo also and of Nájera, or Álava").[6]

In 1721, as part of his drive to both westernize the Russian Empire and assert the monarchy's claim that it was the successor to the Byzantine emperors, Peter the Great imported the Latin word directly into Russian and styled himself imperator (Императоръ). The style remained the official one for all his successors down to the end of the Russian Empire in 1917, though the Russian rulers continued to be colloquially known as tsar (a word derived from "Caesar"), which they had begun to use c. 1480 to likewise assert their contention to be the heirs to the Byzantine state (see: Third Rome.) Reigning female Russian rulers were styled imperatritsa.

Napoleon famously adopted the title for himself and after the Napoleonic wars, the number of emperors in Europe proliferated, but Latin began to fall out of use for all but the most ceremonial situations. Still, in those rare cases in which a European monarch's Latin titles were used, imperator was used as a translation for emperor. Famously, after assuming the title Emperor of India, British monarchs would follow their signatures with the initials RI, standing for rex imperator ("king-emperor"). George VI of the United Kingdom was the last European ruler to claim an imperial title; when he abdicated as Emperor of India in 1948, the last active use of the title imperator in the West ceased. It was thereafter used only historically, or as a Latin translation for certain continuing titles of non-European cultures, such as Japan.

The imperial title was also adopted by Jean-Bédel Bokassa, during his reign as the emperor of the short-lived Central African Empire (1976–79).


The term imperatrix seems not to have been used in Ancient Rome to indicate the consort of an imperator or later of an Emperor. In the early years of the Roman Empire there was no standard title or honorific for the Emperor's wife, even the "Augusta" honorific was rather exceptionally granted, and not exclusively to wives of living emperors.

It is not clear when the feminine form of the Latin term imperator originated or was used for the first time. It usually indicates a reigning monarch, and is thus used in the Latin version of titles of modern reigning Empresses.

Likewise, when Fortuna is qualified "imperatrix mundi" in the Carmina Burana there's no implication of any type of consort — the term describes (the Goddess or personified) Fortune "ruling the world".

In Christian context, Imperatrix became a laudatory address to the Virgin Mary, in diverse forms at least since the Middle Ages — for example, she is sometimes called "Imperatrix angelorum" ("ruler of the angels").


Imperator is the root of most Romance languages' word for emperor. It is the root of the English word "emperor", which entered the language via the French empereur, while related adjectives like "imperial" were imported into English directly from Latin.

Augustus (Latin: Imperator Caesar Divi filius Augustus; 23 September 63 BC – 19 August AD 14) was a Roman statesman and military leader who was the first emperor of the Roman Empire, reigning from 27 BC until his death in AD 14. His status as the founder of the Roman Principate has consolidated an enduring legacy as one of the most effective and controversial leaders in human history. The reign of Augustus initiated an era of relative peace known as the Pax Romana. The Roman world was largely free from large-scale conflict for more than two centuries, despite continuous wars of imperial expansion on the Empire's frontiers and the year-long civil war known as the "Year of the Four Emperors" over the imperial succession.

Augustus was born Gaius Octavius Thurinus into an old and wealthy equestrian branch of the plebeian gens Octavia. His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar's will as his adopted son and heir. Along with Mark Antony and Marcus Lepidus, he formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at the Battle of Philippi, the Triumvirate divided the Roman Republic among themselves and ruled as military dictators. The Triumvirate was eventually torn apart by the competing ambitions of its members. Lepidus was driven into exile and stripped of his position, and Antony committed suicide following his defeat at the Battle of Actium by Octavian in 31 BC.

After the demise of the Second Triumvirate, Augustus restored the outward façade of the free Republic, with governmental power vested in the Roman Senate, the executive magistrates, and the legislative assemblies. In reality, however, he retained his autocratic power over the Republic as a military dictator. By law, Augustus held a collection of powers granted to him for life by the Senate, including supreme military command, and those of tribune and censor. It took several years for Augustus to develop the framework within which a formally republican state could be led under his sole rule. He rejected monarchical titles, and instead called himself Princeps Civitatis ("First Citizen of the State"). The resulting constitutional framework became known as the Principate, the first phase of the Roman Empire.

Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia, expanding possessions in Africa, and completing the conquest of Hispania, but suffered a major setback in Germania. Beyond the frontiers, he secured the Empire with a buffer region of client states and made peace with the Parthian Empire through diplomacy. He reformed the Roman system of taxation, developed networks of roads with an official courier system, established a standing army, established the Praetorian Guard, created official police and fire-fighting services for Rome, and rebuilt much of the city during his reign. Augustus died in AD 14 at the age of 75, probably from natural causes. However, there were unconfirmed rumors that his wife Livia poisoned him. He was succeeded as emperor by his adopted son (also stepson and former son-in-law) Tiberius.

Ave Imperator, morituri te salutant

"Ave, Imperator, morituri te salutant" ("Hail, Emperor, those who are about to die salute you") is a well-known Latin phrase quoted in Suetonius, De Vita Caesarum ("The Life of the Caesars", or "The Twelve Caesars"). It was reportedly used during an event in AD 52 on Lake Fucinus by naumachiarii—captives and criminals fated to die fighting during mock naval encounters—in the presence of the emperor Claudius. Suetonius reports that Claudius replied "Aut non" ("or not").

Variant wordings include "Ave Caesar" and "Morituri te salutamus"—the latter in the 1st person ("We who are about to die salute you")—and a response in 15th-century texts of "Avete vos" ("Fare you well").Despite its popularization in later times, the phrase is not recorded elsewhere in Roman history. Historians question whether it was ever used as a customary salute. It was more likely an isolated appeal by desperate captives and criminals condemned to die, and noted by Roman historians in part for the unusual mass reprieve granted by Claudius to the survivors.

Columbian mammoth

The Columbian mammoth (Mammuthus columbi) is an extinct species of mammoth that inhabited North America as far north as the northern United States and as far south as Costa Rica during the Pleistocene epoch. It was one of the last in a line of mammoth species, beginning with Mammuthus subplanifrons in the early Pliocene. The Columbian mammoth evolved from the steppe mammoth, which entered North America from Asia about 1.5 million years ago. The pygmy mammoths of the Channel Islands of California evolved from Columbian mammoths. The closest extant relative of the Columbian and other mammoths is the Asian elephant.

Reaching 4 m (13 ft) at the shoulders and 10 tonnes (22,000 lb) in weight, the Columbian mammoth was one of the largest species of mammoth. It had long, curved tusks and four molars, which were replaced six times during the lifetime of an individual. It most likely used its tusks and trunk like modern elephants—for manipulating objects, fighting, and foraging. Bones, hair, dung, and stomach contents have been discovered, but no preserved carcasses are known. The Columbian mammoth preferred open areas, such as parkland landscapes, and fed on sedges, grasses, and other plants. It did not live in the Arctic regions of Canada, which were instead inhabited by woolly mammoths. The ranges of the two species may have overlapped, and genetic evidence suggests that they interbred. Several sites contain the skeletons of multiple Columbian mammoths, either because they died in incidents such as a drought, or because these locations were natural traps in which individuals accumulated over time.

For a few thousand years prior to their extinction, Columbian mammoths coexisted in North America with Paleoamericans – the first humans to inhabit the Americas – who hunted them for food, used their bones for making tools, and depicted them in ancient art. Columbian mammoth remains have been found in association with Clovis culture artifacts; these remains may have stemmed either from hunting or scavenging. The Columbian mammoth disappeared at the end of the Pleistocene around 11,500 years ago, most likely as a result of habitat loss caused by climate change, hunting by humans, or a combination of both.

The emperor rat (Uromys imperator) is a large species of rodent in the family Muridae. It is endemic to the island of Guadalcanal in the Solomon Islands. It is classified as critically endangered by the IUCN but may already be extinct.

Emperor tamarin

The emperor tamarin (Saguinus imperator), is a species of tamarin allegedly named for its resemblance to the German emperor Wilhelm II. It lives in the southwest Amazon Basin, in east Peru, north Bolivia and in the west Brazilian states of Acre and Amazonas.The fur of the emperor tamarin is predominantly grey colored, with yellowish speckles on its chest. The hands and feet are black and the tail is brown. Outstanding is its long, white beard, which extends to both sides beyond the shoulders. The animal reaches a length of 23–26 centimetres (9–10 in), plus a 35–41.5 cm (13.8–16.3 in) long tail. It weighs approximately 500 grams (18 oz).

Holy Roman Emperor

The Holy Roman Emperor (also "German-Roman Emperor", German: Römisch-deutscher Kaiser "Roman-German emperor"; historically Imperator Romanorum, "Emperor of the Romans") was the ruler of the Holy Roman Empire (considered by itself to be the successor of the Roman Empire) during the Middle Ages and the early modern period. The title was, almost without interruption, held in conjunction with title of King of Germany (rex teutonicorum) throughout the 12th to 18th centuries.From an autocracy in Carolingian times (AD 800–924) the title by the 13th century evolved into an elected monarchy chosen by the prince-electors.

Various royal houses of Europe, at different times, became de facto hereditary holders of the title, notably the Ottonians (962–1024) and the Salians (1027–1125). Following the late medieval crisis of government, the Habsburgs kept possession of the title without interruption from 1440–1740. The final emperors were from the House of Lorraine (Habsburg-Lorraine), from 1765–1806. The Holy Roman Empire was dissolved by Emperor Francis II, after a devastating defeat to Napoleon at the Battle of Austerlitz.

The Holy Roman Emperor was widely perceived to rule by divine right, though he often contradicted or rivaled the Pope, most notably during the Investiture controversy.

In theory, the Holy Roman Emperor was primus inter pares (first among equals) among other Catholic monarchs. In practice, a Holy Roman Emperor was only as strong as his army and alliances, including marriage alliances, made him. There was never a Holy Roman Empress regnant, though women such as Theophanu and Maria Theresa of Austria served as de facto Empresses regnant.

Throughout its history, the position was viewed as a defender of the Roman Catholic faith. Until the Reformation, the Emperor elect (imperator electus) was required to be crowned by the Pope before assuming the imperial title. Charles V, Holy Roman Emperor was the last to be crowned by the Pope in 1530. Even after the Reformation, the elected Emperor always was a Roman Catholic. There were short periods in history when the electoral college was dominated by Protestants, and the electors usually voted in their own political interest.

Imperator Aleksandr II-class battleship

The Imperator Aleksandr II-class battleships were two battleships built for the Imperial Russian Navy in the 1880s. They were intended to counter the small armored ships of the other Baltic powers. Construction was very prolonged and the ships were virtually obsolescent when completed. They were optimized for ramming.

Imperator Aleksandr II served in the Baltic and Mediterranean Seas before becoming a gunnery training ship in 1904, but she was inactive during World War I before joining the Bolsheviks in 1917. She was sold for scrap in 1922. Imperator Nikolai I served in the Baltic and Mediterranean Seas as well as the Pacific Ocean during the First Sino-Japanese War and the Russo-Japanese War. She surrendered after the Battle of Tsushima in 1905 and was commissioned in the Imperial Japanese Navy before she was sunk as a target in 1915.

List of Roman emperors

The Roman emperors were the rulers of the Roman Empire dating from the granting of the title of Augustus to Gaius Julius Caesar Octavianus by the Roman Senate in 27 BC. Augustus maintained a façade of Republican rule, rejecting monarchical titles but calling himself princeps senatus (first man of the council) and princeps civitatis (first citizen of the state). The title of Augustus was conferred on his successors to the imperial position. The style of government instituted by Augustus is called the Principate and continued until reforms by Diocletian. The modern word 'emperor' derives from the title imperator, which was granted by an army to a successful general; during the initial phase of the empire, the title was generally used only by the princeps. For example, Augustus' official name was Imperator Caesar Divi Filius Augustus.

The territory under command of the emperor had developed under the period of the Roman Republic as it invaded and occupied most of Europe and portions of northern Africa and western Asia. Under the republic, regions of the empire were ruled by provincial governors answerable to and authorised by the Senate and People of Rome. During the republic, the chief magistrates of Rome were two consuls elected each year; consuls continued to be elected in the imperial period, but their authority was subservient to that of the emperor, and the election was controlled by the emperor.

In the late 3rd century, after the Crisis of the Third Century, Diocletian formalised and embellished the recent manner of imperial rule, establishing the so-called Dominate period of the Roman Empire. This was characterised by the explicit increase of authority in the person of the Emperor, and the use of the style Dominus Noster ("Our Lord"). The rise of powerful Barbarian tribes along the borders of the empire and the challenge they posed to defense of far-flung borders and unstable imperial succession led Diocletian to divide the administration geographically of the Empire in 286 with a co-Augustus. In 330, Constantine the Great established a second capital in Byzantium, which he renamed Constantinople. For most of the period from 286 to 480, there was more than one recognised senior emperor, with the division usually based in geographic terms. This division was consistently in place after the death of Theodosius I in 395, which historians have dated as the division between the Western Roman Empire and the Eastern Roman Empire. However, formally the Empire remained a single polity, with separate co-emperors in the separate courts. The fall of the Western Roman Empire, and so the end of a separate list of emperors below, is dated either from the de facto date of 476 when Romulus Augustulus was deposed by the Germanic Herulians led by Odoacer or the de jure date of 480, on the death of Julius Nepos, when Eastern Emperor Zeno ended recognition of a separate Western court. In the period that followed, the Empire is usually treated by historians as the Byzantine Empire governed by the Byzantine Emperors, although this designation is not used universally, and continues to be a subject of specialist debate today.The line of emperors continued until the death of Constantine XI Palaiologos during the Fall of Constantinople in 1453, when the remaining territories were captured by the Ottoman Empire under Mehmed II.Counting all individuals to have possessed the full imperial title, including those who did not technically rule in their own right (e.g. co-emperors or minors during regencies), this list contains 192 emperors and 5 ruling empresses, for a total of 197 monarchs.

Roman emperor

The Roman emperor was the ruler of the Roman Empire during the imperial period (starting in 27 BC). The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title Augustus or Caesar. Another title often used was imperator, originally a military honorific. Early Emperors also used the title princeps (first citizen). Emperors frequently amassed republican titles, notably princeps senatus, consul and pontifex maximus.

The legitimacy of an emperor's rule depended on his control of the army and recognition by the Senate; an emperor would normally be proclaimed by his troops, or invested with imperial titles by the Senate, or both. The first emperors reigned alone; later emperors would sometimes rule with co-emperors and divide administration of the empire between them.

The Romans considered the office of emperor to be distinct from that of a king. The first emperor, Augustus, resolutely refused recognition as a monarch. Although Augustus could claim that his power was authentically republican, his successor, Tiberius, could not convincingly make the same claim. Nonetheless, for the first three hundred years of Roman emperors, from Augustus until Diocletian, efforts were made to portray the emperors as leaders of a republic.

From Diocletian, whose tetrarchic reforms also divided the position into one emperor in the West and one in the East, until the end of the Empire, emperors ruled in an openly monarchic style and did not preserve the nominal principle of a republic, but the contrast with "kings" was maintained: although the imperial succession was generally hereditary, it was only hereditary if there was a suitable candidate acceptable to the army and the bureaucracy, so the principle of automatic inheritance was not adopted. Elements of the republican institutional framework (senate, consuls, and magistrates) were preserved even after the end of the Western Empire.

The Western Roman Empire collapsed in the late 5th century after multiple invasions of imperial territory by Germanic barbarian tribes. Romulus Augustulus is often considered to be the last emperor of the West after his forced abdication in 476, although Julius Nepos maintained a claim recognized by the Eastern Empire to the title until his death in 480. Following Nepos' death, the Eastern Emperor Zeno abolished the division of the position and proclaimed himself as the sole Emperor of a reunited Roman Empire. The Eastern imperial lineage continued to rule from Constantinople ("New Rome"); they continued to style themselves as Emperor of the Romans (later βασιλεύς Ῥωμαίων in Greek), but are often referred to in modern scholarship as Byzantine emperors. Constantine XI Palaiologos was the last Roman emperor in Constantinople, dying in the Fall of Constantinople to the Ottomans in 1453.

The "Byzantine" emperors from Heraclius in 629 and onwards adopted the title of basileus (βασιλεύς), which had originally meant king in Greek but became a title reserved solely for the Roman emperor and the ruler of the Sasanian Empire. Other kings were then referred to as rēgas.In addition to their pontifical office, some emperors were given divine status after death. With the eventual hegemony of Christianity, the emperor came to be seen as God's chosen ruler, as well as a special protector and leader of the Christian Church on Earth, although in practice an emperor's authority on Church matters was subject to challenge.

Due to the cultural rupture of the Turkish conquest, most western historians treat Constantine XI as the last meaningful claimant to the title Roman Emperor. From 1453, one of the titles used by the Ottoman Sultans was "Caesar of Rome" (Turkish: Kayser-i Rum), part of their titles until the Ottoman Empire ended in 1922. A Byzantine group of claimant Roman emperors existed in the Empire of Trebizond until its conquest by the Ottomans in 1461, though they had used a modified title since 1282.

Eastern emperors in Constantinople had been recognized and accepted as Roman emperors both in the East, which they ruled, and by the Papacy and Germanic kingdoms of the West until the deposition of Constantine VI and accession of Irene of Athens as Empress regnant in 797. Objecting to a woman ruling the Roman Empire in her own right and issues with the eastern clergy, the Papacy would then create a rival lineage of Roman emperors in western Europe, the Holy Roman Emperors, which ruled the Holy Roman Empire for most of the period between 800 and 1806. These Emperors were never recognized as Roman emperors by the court in Constantinople.

Russian battleship Imperator Aleksandr III

Imperator Aleksandr III (Emperor Alexander III) was the third, and last, ship of the Imperatritsa Mariya-class dreadnoughts of the Imperial Russian Navy. She was begun before World War I, completed in 1917 and saw service with the Black Sea Fleet. She was renamed Volia or Volya (Russian: Вóля, Freedom) before her completion and then General Alekseyev (Russian: Генерал Алексеев) in 1920. The ship did not take part in operations during World War I because her sister ships were given a higher priority for completion. She was delivered in 1917, but the disruptions of the February Revolution rendered the Black Sea Fleet ineffective and she saw no combat.

Volia was surrendered to the Germans in 1918, but they were forced to turn her over to the British by the terms of the Armistice. The British turned her over to the White Russians in 1919 and they used her to help evacuate the Crimea in 1920. She was interned in Bizerte by the French and ultimately scrapped by them in 1936 to pay her docking fees. Her guns were put into storage and were later used by the Germans and Finns for coastal artillery during World War II. The Finns and the Soviets continued to use them throughout the Cold War.

Russian battleship Imperator Aleksandr III (1901)

Imperator Alexandr III (Russian: Император Александр III) was a Borodino-class battleship built for the Russian Imperial Navy in the first decade of the 20th century. The design of the Borodino class was derived from that of the French-designed battleship Tsesarevich. The ship was completed a few months before the start of the Russo-Japanese War in February 1904 and was assigned to the Second Pacific Squadron sent to the Far East six months later to break the Japanese blockade of Port Arthur. The Japanese captured the port while the squadron was in transit and their destination was changed to Vladivostok. During the Battle of Tsushima in May 1905, Imperator Alexandr III was sunk by Japanese gunfire with the loss of 778 men, her entire crew.

Russian battleship Imperator Nikolai I (1889)

Imperator Nikolai I (Russian: Император Николай I) was a Russian Imperator Aleksandr II-class battleship built for the Baltic Fleet in the late 1880s. She participated in the celebration of the 400th anniversary of the discovery of America in New York City in 1892. She assigned to the Mediterranean Squadron and visited Toulon in October 1893. She sailed for the Pacific Ocean during the First Sino-Japanese War and remained in the Pacific until late 1896, when she returned to the Mediterranean Squadron and supported Russian interests during the Cretan Revolt. She returned to the Baltic in April 1898 and had a lengthy refit, which replaced all of her machinery, before returning to the Mediterranean in 1901.

Returning to the Baltic during the Russo-Japanese War Imperator Nikolai I was refitted in late 1904 to serve as the flagship of the Third Pacific Squadron under Rear Admiral Nikolai Nebogatov. She was slightly damaged during the Battle of Tsushima and was surrendered, along with most of the Third Pacific Squadron, by Admiral Nebogatov to the Japanese the following day. She was taken into the Imperial Japanese Navy under the new name of Iki (壱岐) and she served as a gunnery training ship until 1910 and then became a first-class coast defense ship and training vessel. She was sunk as a target ship in October 1915.

SS Imperator

SS Imperator was an ocean liner built for the Hamburg America Line (Hamburg Amerikanische Paketfahrt Aktien Gesellschaft, or HAPAG), launched in 1912. Although in Europe, with the exception of Italy and France, all ships are usually referred to as feminine, during the Liner’s Hamburg American Line career the ship was to be referred to as masculine at the special request of Kaiser Wilhelm II. At the time of his completion in June 1913, he was the largest passenger ship in the world by gross tonnage, surpassing the new White Star giant, “Olympic” and “Titanic” had she not sank.

“Imperator” was the first of a trio of successively larger Hamburg American liners that included S.S. Vaterland (Later the United States Liner Leviathan) and S.S. ‘‘Bismarck’’ (Purchased and renamed “Majestic” for the White Star Line transatlantic passenger service).

During World War I, the ship remained in port in Hamburg. After the war, he was briefly commissioned into the United States Navy as USS Imperator (ID-4080) and employed as a transport, returning American troops from Europe. Following his service with the U.S. Navy, Imperator was handed over to Britain's Cunard Line as part of war reparations where he sailed as the flagship RMS Berengaria for the final decade of his career.


Sarcosuchus (; meaning "flesh crocodile") is an extinct genus of crocodyliform and distant relative of living crocodylians that lived 112 million years ago. It dates from the early Cretaceous Period of what is now Africa and South America and is one of the largest crocodile-like reptiles that ever lived. It was almost twice as long as the modern saltwater crocodile and weighed up to 8 tonnes (7.9 long tons; 8.8 short tons).

The first remains were discovered during several expeditions led by the French paleontologist Albert-Félix de Lapparent, spanning from 1946 to 1959, in the Sahara. These remains were fragments of the skull, vertebrae, teeth, and scutes. In 1964, an almost complete skull was found in Niger by the French CEA, but it was not until 1997 and 2000 that most of its anatomy became known to science, when an expedition led by the American paleontologist Paul Sereno discovered six new specimens, including one with about half the skeleton intact and most of the spine.

Tsar ( or ; Old Church Slavonic: ц︢рь [usually written thus with a title] or цар, царь), also spelled czar, or tzar, is a title used to designate East and South Slavic monarchs or supreme rulers of Eastern Europe, originally Bulgarian monarchs from 10th century onwards. As a system of government in the Tsardom of Russia and the Russian Empire, it is known as Tsarist autocracy, or Tsarism. The term is derived from the Latin word Caesar, which was intended to mean "Emperor" in the European medieval sense of the term—a ruler with the same rank as a Roman emperor, holding it by the approval of another emperor or a supreme ecclesiastical official (the Pope or the Ecumenical Patriarch)—but was usually considered by western Europeans to be equivalent to king, or to be somewhat in between a royal and imperial rank.

"Tsar" and its variants were the official titles of the following states:

First Bulgarian Empire, in 919–1018

Second Bulgarian Empire, in 1185–1396

Serbian Empire, in 1346–1371

Tsardom of Russia, in 1547–1721 (replaced in 1721 by imperator, but still remaining in use, also officially in relation to several regions until 1917)

Tsardom of Bulgaria, in 1908–1946The first ruler to adopt the title tsar was Simeon I of Bulgaria. Simeon II, the last Tsar of Bulgaria, is the last person to have borne the title Tsar.
