Battle of Dyrrhachium (1018)

The Battle of Dyrrhachium in February 1018 was a part of the Byzantine-Bulgarian Wars. It happened as the Bulgarian tsar Ivan Vladislav tried to establish his power on the southeastern coast of the Adriatic Sea. He led an army against Dyrrhachium (present-day Durrës, in Albania) and besieged it, but was killed during a counterattack of the city’s defenders.

This was the final battle of the centuries long struggle between the First Bulgarian Empire and Byzantium. Within months after Vladislav’s death most of his realm was subjugated by the Byzantine emperor Basil II, with the last independent region (Sirmium) subdued in 1019.

Bolesław I's intervention in the Kievan succession crisis

The intervention in the Kievan succession crisis of 1015–1019 by the Polish ruler Bolesław Chrobry was an episode in the struggle between Sviatopolk I Vladimirovich ("the Accursed") and his brother Yaroslav ("the Wise") for the rulership of Kiev and Kievan Rus'. It occurred when Sviatopolk's father-in-law Bolesław, ruler of Poland, intervened on Sviatopolk's behalf.

The intervention was initially successful as Bolesław defeated Yaroslav's armies, and temporarily secured the throne for Sviatopolk. But when Bolesław withdrew himself and his army from Kiev, Sviatopolk was unable to retain his position, being defeated by Yaroslav in the following year. Chronicles of the expedition include legendary accounts as well as factual history and have been subject to varied interpretations.

Bulgaria (theme)

The Theme of Bulgaria was a province of the Byzantine Empire established by Emperor Basil II after the conquest of Bulgaria in 1018. Its capital was Skopje and it was governed by a strategos.

Initially the Byzantine emperor Basil II issued an order that the tax system of the subdued Bulgarian kingdom continue to be applied in the annexed Bulgarian lands. The Bulgarian patriarchate was downgraded to an archbishopric called Archbishopric of Ohrid, that retained an autocephalous status. The Bulgarian aristocracy also retained its position. Troops were recruited mainly from the Bulgarian population. However, only ten years later after the dead of Basil II, the Byzantine tax system was introduced. Slavic literacy, liturgy and traditions of the Archbishopric were in some places subjected to persecution. The some of the Bulgarian aristocracy had slowly but consistently been removed from its position. Many were sent on assignments in other realms of the Empire remote from the Balkans. This situation gave rise to discontent among the local population. Rebellions aimed at restoration of the Bulgarian state broke out. The first one rose in Belgrade in 1040. It was headed by Petar Deljan, grandson of Tsar Samuel. Another insurgence broke out in 1072 led by Georgi Voiteh in the town of Skopje. At the end of the 11th century the Byzantine domains in the Balkans became an arena of fierce hostilities. The Normans invaded from the south and the knights of the First (1096–97) and then the Second Crusade (1146–47) advanced from west. Most frightful were the renewed raids of the Turkic barbarians from the steppes, the Uzes, the Pechenegs and the Cumans. At the end of the 12th century, formally Byzantium was the sovereign, but in many Balkan areas the Byzantine power was nominal. In 1185, the Normans landed in Dyrrachium again, moved east and looted Salonika. The chaos in the imperial domains encouraged the Bulgarians to restore their state with the rebellion of the brothers Peter and Asen, and Bulgaria sought again to dominate the Balkans. The disintegration of Byzantium was complete when in 1204 the Fourth Crusade captured Constantinople. The Latins abolished the Byzantine Empire and set up their own feudal states in the southern Balkans.

Byzantine conquest of Bulgaria

From ca. 970 until 1018, a series of conflicts between the Bulgarian Empire and the Byzantine Empire led to the gradual conquest of Bulgaria by the Byzantines, who thus re-established their control over the entire Balkan peninsula for the first time since the 7th-century Slavic invasions. The struggle began with the incorporation of eastern Bulgaria after the Russo–Byzantine War (970–971). Bulgarian resistance was led by the Cometopuli brothers, who based in the unconquered western regions of the Bulgarian Empire led it until its fall under Byzantine rule in 1018.As the Byzantine-Bulgarian relations deteriorated by the end of the 960s, the Eastern Roman Empire paid the Kievan prince Sviatoslav to attack Bulgaria. The unexpected collapse of Bulgaria and Sviatoslav's ambitions to seize Constantinople caught the Eastern Roman Empire off-guard but they managed to pull back the Kievan armies and occupied eastern Bulgaria including the capital Preslav in 971. Emperor Boris II was captured and taken to Constantinople where he abdicated and the Byzantine Emperor John I Tzimiskes announced the annexation of Bulgaria, even though the Eastern Roman Empire only controlled Eastern Bulgaria at the time, but the lands to the west remained under Bulgarian control. The four brothers David, Moses, Aron and Samuel of the Cometopuli dynasty ruled in the free territories and in 976 launched a major offensive against the Byzantines to regain the lost lands. Soon the youngest brother Samuel took the whole authority following the deaths of his three eldest brothers.

Samuel proved to be a successful general inflicting a major defeat on the Byzantine army commanded by Basil II at the Gates of Trajan and retaking north-eastern Bulgaria. His successful campaigns expanded the Bulgarian borders into Thessaly and Epirus and in 998 he conquered the principality of Duklja. In 997 Samuel was proclaimed Emperor of Bulgaria after the death of the legitimate ruler, Roman.

By the end of the millennium the fortunes of war turned into Byzantine favour. The Byzantines under Basil II, a successful general and experienced soldier, slowly got the upper hand and from 1001 started to seize a number of important areas and towns. The Bulgarians were unable to stop the annual Byzantine campaigns which devastated the country. In 1014 the Byzantines won the decisive battle of Kleidion and Samuel died a few weeks later. Tsar Samuel's reign was followed by the short reigns of his son Gavril Radomir and his nephew Ivan Vladislav. In 1018, Ivan Vladislav's widow, Maria, negotiated very favorable terms of surrender to the Byzantine emperor. All local lords who surrendered were transferred either to Constantinople or to Anatolia and most of them were later assimilated into the Byzantine society. Bulgaria lost its independence and remained subject to Byzantium for more than a century and a half, until 1185. Its western part was transformed into one of the many Byzantine's provinces, which was ruled by a governor appointed by the Emperor. With the collapse of the first Bulgarian state, the Bulgarian church fell under the domination of Greek ecclesiastics who took control of the see of Ohrid and attempted to replace the Bulgarian Slavic liturgy with a Greek liturgy.

Carbon steel

Carbon steel is a steel with carbon content up to 2.1% by weight. The definition of carbon steel from the American Iron and Steel Institute (AISI) states:

Steel is considered to be carbon steel when:

no minimum content is specified or required for chromium, cobalt, molybdenum, nickel, niobium, titanium, tungsten, vanadium or zirconium, or any other element to be added to obtain a desired alloying effect;

the specified minimum for copper does not exceed 0.40 percent;

or the maximum content specified for any of the following elements does not exceed the percentages noted: manganese 1.65, silicon 0.60, copper 0.60.The term "carbon steel" may also be used in reference to steel which is not stainless steel; in this use carbon steel may include alloy steels.

As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.

Code page 1018, also known as CP1018, is IBM's code page for the Swedish and Finnish version of ISO 646 (ISO-646-FI / ISO-646-SE / IR-10), specified in SFS 4017 and SEN 850200 Annex B, SIS 63 61 27.


The coulomb (symbol: C) is the International System of Units (SI) unit of electric charge. It is the charge (symbol: Q or q) transported by a constant current of one ampere in one second:

Thus, it is also the amount of excess charge on a capacitor of one farad charged to a potential difference of one volt:

The coulomb is equivalent to the charge of approximately 6.242×1018 (1.036×10−5 mol) protons, and −1 C is equivalent to the charge of approximately 6.242×1018 electrons.

A new definition, in terms of the elementary charge, will take effect on 20 May 2019. The new definition defines the elementary charge (the charge of the proton) as exactly 1.602176634×10−19 coulombs.

First Bulgarian Empire

The First Bulgarian Empire (Old Bulgarian: ц︢рьство бл︢гарское, ts'rstvo bl'garskoe) was a medieval Bulgarian state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 681 when Bulgar tribes led by Asparuh moved to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeating – possibly with the help of local South Slavic tribes – the Byzantine army led by Constantine IV. At the height of its power, Bulgaria spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea.

As the state solidified its position in the Balkans, it entered into a centuries-long interaction, sometimes friendly and sometimes hostile, with the Byzantine Empire. Bulgaria emerged as Byzantium's chief antagonist to its north, resulting in several wars. The two powers also enjoyed periods of peace and alliance, most notably during the Second Arab siege of Constantinople, where the Bulgarian army broke the siege and destroyed the Arab army, thus preventing an Arab invasion of Southeastern Europe. Byzantium had a strong cultural influence on Bulgaria, which also led to the eventual adoption of Christianity in 864. After the disintegration of the Avar Khaganate, the country expanded its territory northwest to the Pannonian Plain. Later the Bulgarians confronted the advance of the Pechenegs and Cumans, and achieved a decisive victory over the Magyars, forcing them to establish themselves permanently in Pannonia.

During the late 9th and early 10th centuries, Simeon I achieved a string of victories over the Byzantines. Thereafter, he was recognized with the title of Emperor, and proceeded to expand the state to its greatest extent. After the annihilation of the Byzantine army in the battle of Anchialus in 917, the Bulgarians laid siege to Constantinople in 923 and 924. The Byzantines, however, eventually recovered, and in 1014, under Basil II, inflicted a crushing defeat on the Bulgarians at the Battle of Kleidion. By 1018, the last Bulgarian strongholds had surrendered to the Byzantine Empire, and the First Bulgarian Empire had ceased to exist. It was succeeded by the Second Bulgarian Empire in 1185.

After the adoption of Christianity, Bulgaria became the cultural center of Slavic Europe. Its leading cultural position was further consolidated with the invention of the Glagolitic and Early Cyrillic alphabets shortly after in the capital Preslav, and literature produced in Old Bulgarian soon began spreading north. Old Bulgarian became the lingua franca of much of Eastern Europe and it came to be known as Old Church Slavonic. In 927, the fully independent Bulgarian Patriarchate was officially recognized.

The ruling Bulgars and other non-Slavic tribes in the empire gradually mixed and adopted the prevailing Slavic language, thus gradually forming the Bulgarian nation from the 7th century to the 9th century. Since the late 9th century, the names Bulgarians and Bulgarian gained prevalence and became permanent designations for the local population, both in literature and in common parlance. The development of Old Church Slavonic literacy had the effect of preventing the assimilation of the South Slavs into neighbouring cultures, while stimulating the formation of a distinct Bulgarian identity.

German submarine U-1018

German submarine U-1018 was a German Type VIIC/41 U-boat, built during World War II for service in the Battle of the Atlantic. The U-boat was fitted with the Schnorchel underwater-breathing apparatus which enabled her to stay under-water for extended periods thus avoiding detection by enemy warships.

German–Polish War (1002–18)

The German–Polish War which took place from 1002 to 1018 consisted of a series of struggles between the Ottonian king Henry II of Germany (Holy Roman Emperor from 1014) and the Polish Piast ruler Bolesław I the Brave. The locus of conflict was the control of Lusatia, Upper Lusatia, as well as Bohemia, Moravia and Slovakia. The fighting ended with the Peace of Bautzen in 1018, which left Lusatia and Upper Lusatia as a fief to Poland, and Bohemia became a duchy in the Holy Roman Empire.

Harald II of Denmark

Harald II of Denmark (died 1018) was King of Denmark from 1014 until his death in 1018. He was the youngest son of Sweyn Forkbeard and Gunhild of Wenden, and was regent while his father was fighting Ethelred the Unready in England. He inherited the Danish throne in 1014, and held it while his brother, the later king Cnut the Great conquered England. After his death in 1018, he was succeeded by Cnut the Great. Little detail is known about Harald II.


The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Hertz are commonly expressed in multiples: kilohertz (103 Hz, kHz), megahertz (106 Hz, MHz), gigahertz (109 Hz, GHz), terahertz (1012 Hz, THz), petahertz (1015 Hz, PHz), and exahertz (1018 Hz, EHz).

Some of the unit's most common uses are in the description of sine waves and musical tones, particularly those used in radio- and audio-related applications. It is also used to describe the speeds at which computers and other electronics are driven.

List of Bulgarian monarchs

The monarchs of Bulgaria ruled the country during three periods of its history as an independent country: from the establishment of the First Bulgarian Empire in 681 to the Byzantine conquest of Bulgaria in 1018; from the Uprising of Asen and Peter that established the Second Bulgarian Empire in 1185 to the annexation of the rump Bulgarian principality into the Ottoman Empire in 1422; and from the re-establishment of an independent Bulgaria in 1878 to the abolition of monarchy in a manipulated referendum held on 15 September 1946.

Early Bulgarian rulers possibly used the title Kanasubigi (khan), later knyaz (prince) for a brief period, and subsequently tsar (emperor). The title tsar, the Bulgarian form of the Latin Caesar, was first adopted and used in Bulgaria by Simeon I, following a decisive victory over the Byzantine Empire in 913. It was also used by all of Simeon I's successors until the fall of Bulgaria under Ottoman rule in 1396. After Bulgaria's liberation from the Ottomans in 1878, its first monarch Alexander I adopted the title knyaz, or prince. However, when de jure independence was proclaimed under his successor Ferdinand in 1908, the title was elevated to the customary tsar once more. The use of tsar continued under Ferdinand and later under his heirs Boris III and Simeon II until the abolition of monarchy in 1946.

While the title tsar was translated as "emperor" in the First and Second Bulgarian Empires, it was translated as "king" in modern Bulgaria.

In the few surviving medieval Bulgarian royal charters, the monarchs of Bulgaria styled themselves as "In Christ the Lord Faithful Emperor and Autocrat of all Bulgarians" or similar variations, sometimes including “... and Romans, Greeks, or Vlachs".

This list does not include the mythical Bulgar rulers and the rulers of Old Great Bulgaria listed in the Nominalia of the Bulgarian khans as well as unsuccessful claimants to the throne who are not generally listed among the Bulgarian monarchs.

List of Jordanian detainees at Guantanamo Bay

The United States Department of Defense acknowledges holding eight Jordanian captives in Guantanamo.

A total of 778 captives have been held in extrajudicial detention in the Guantanamo Bay detention camps, in Cuba since the camps opened on January 11, 2002

The camp population peaked in 2004 at approximately 660. Only nineteen new captives, all "high value detainees" have been transferred there since the United States Supreme Court's ruling in Rasul v. Bush. As of July 2012 the camp population was at approximately 170. This number had dropped to 40 by May of 2018.

List of kings of Leinster

The following is a provisional list of the Kings of Leinster who ruled the Irish kingdom of Leinster (or Laigin) up to 1632 with the death of Domhnall Spainneach Mac Murrough Caomhanach, the last legitimately inaugurated head of the MacMurrough Kavanagh royal line. However, not last of the Leinster royal line. Today's province of Leinster is considerably larger than the former kingdom.

Nizam al-Mulk

Abu Ali Hasan ibn Ali Tusi (April 10, 1018 – October 14, 1092), better known by his honorific title of Nizam al-Mulk (Persian: نظام‌الملک‎, "Order of the Realm" ) was a Persian scholar and vizier of the Seljuq Empire. Rising from a lowly position, he was the de facto ruler of the empire for 20 years after the assassination of Alp Arslan in 1072, with a apotheosis as the Islamic history's archetypal good vizier.One of his most important legacies was founding schools in cities throughout the Seljuk Empire. These were called "nezamiyehs" after him. He wrote Siyasatnama ("Book of Government"), a political treatise that uses historical examples to discuss justice, effective rule, and the role of government in Islamic society.
