Abd al-Jalil ibn Wahbun

Abu Mohammed Abd al-Jalil ibn Wahbun, better known as simply Ibn Wahbun (died 1090), was a poet from Al Andalus in the 11th century. He made his career at the court of Al-Mutamid in Sevilla and the Almoravid court in Marrakesh. He was born in Murcia ca. 1039/1049. He was murdered by Christian raiders on the road from Lorca to Murcia in 1087. One of his poems is the famous ode to the battle of Zalaca.

Bertha of Savoy

Bertha of Savoy (21 September 1051 – 27 December 1087), also called Bertha of Turin, a member of the Burgundian House of Savoy, was Queen consort of Germany from 1066 and Empress consort of the Holy Roman Empire from 1084 until 1087 as the first wife of the Salian emperor Henry IV.

Constantine Doukas (co-emperor)

Constantine Doukas or Ducas (Greek: Κωνσταντίνος Δούκας, Kōnstantinos Doukas), (late 1074 – c. 1095) was Byzantine junior emperor from 1074–1078, and again from 1081–1087. He was born to Emperor Michael VII and Empress Maria of Alania in late 1074, and elevated to junior emperor in the same year. He was junior emperor until 1078, when Michael VII was replaced by Nikephoros III Botaneiates. Because Constantine was not made junior emperor under Nikephoros III, his betrothal to Olympias, the daughter of Robert Guiscard, was broken, which Robert Guiscard used as a pretext to invade the Byzantine Empire. John Doukas forced Nikephoros to abdicate to Alexios I Komnenos in 1081, and shortly after Alexios elevated Constantine to junior emperor under himself. Constantine remained junior emperor until 1087, when Alexios had a son, John II Komnenos. Constantine died in c. 1095.

G 99-47

G 99-47 (V1201 Orionis) is a nearby degenerate star (white dwarf) of spectral class DAP8 (DAP8.9, or DAP8.7), the single known component of the system, located in the constellation Orion.

Goldberg Variations

The Goldberg Variations, BWV 988, is a musical composition for harpsichord by Johann Sebastian Bach, consisting of an aria and a set of 30 variations. First published in 1741, the work is one of the most important examples of the variation form. It is named after Johann Gottlieb Goldberg, who may also have been the first performer of the work.

House of Normandy

The House of Normandy is the usual designation for the family that were the Counts of Rouen, Dukes of Normandy and Kings of England which immediately followed the Norman conquest of England and lasted until the House of Plantagenet came to power in 1154. It included the Viking Rollo and his descendants, and William the Conqueror and his heirs down through 1135. After that it was disputed between William's grandchildren, Matilda, whose husband Geoffrey was the founder of the Angevin Dynasty, and Stephen of the House of Blois (or Blesevin dynasty).

The Norman counts of Rouen were:

Rollo, 911–927

William Longsword, 927–942The Norman dukes of Normandy were:

Richard I, 942–996

Richard II, 996–1027

Kanji (era)

Kanji (寛治) was a Japanese era (年号, nengō, "year name") after Ōtoku and before Kahō. This period spanned the years from April 1087 through December 1094. The reigning emperor was Emperor Horikawa.

List of kings of Connacht

The Kings of Connacht were rulers of the cóiced (variously translated as portion, fifth, province) of Connacht, which lies west of the River Shannon, Ireland. However, the name only became applied to it in the early medieval era, being named after the Connachta.

The old name for the province was Cóiced Ol nEchmacht (the fifth of the Ol nEchmacht). Ptolemy's map of c. 150 AD does in fact list a people called the Nagnatae as living in the west of Ireland. Some are of the opinion that Ptolemy's Map of Ireland may be based on cartography carried out as much as five hundred years before his time.

The Connachta were a group of dynasties who claimed descent from the three eldest sons of Eochaid Mugmedon: Brion, Ailill and Fiachrae. They took their collective name from their alleged descent from Conn Cétchathach. Their younger brother, Niall Noigiallach was ancestor to the Uí Néill.

The following is a list of kings of Connacht from the fifth to fifteenth centuries.

NGC 1087

NGC 1087 is an intermediate spiral galaxy in Cetus. The central bar/core is very small with many irregular features in the surrounding disk of material. With the many strange features of NGC 1087, its true nature is still uncertain. It has an extremely small nucleus and a very short stellar bar. Unlike most barred galaxies, the bar apparently has some new star-formation taking place. There is a multiple spiral structure defined more by the dust lanes than by luminous matter. Overall, the disc has a very low surface brightness. Even though it appears close to another galaxy (NGC 1090), these two galaxies are not interacting and should be considered isolated from one another.

NCG 1087 lies near the small M77 (NGC 1068) galaxy group that also includes NGC 936, NGC 1055, and NGC 1090. However, because of its distance, it probably is not an actual group member.

Based on the published red shift, (Hubble Constant of 62 km/s per Mpc) a rough distance estimate for NGC 1087 is 80 million light-years, with a diameter of about 86,800 light-years. The Type II Supernova 1995V is the only recorded supernova in NGC 1087.

Pope Victor III

Pope Victor III (c. 1026 – 16 September 1087), born Dauferio, was Pope from 24 May 1086 to his death in 1087. He was the successor of Pope Gregory VII, yet his pontificate is far less impressive in history than his time as Desiderius, the great Abbot of Montecassino.

His failing health was the factor that made him so reluctant to accept his pontifical election and his health was so poor that he fell to illness during his papal coronation. The only literary work of his that remains is his "Dialogues" on the miracles performed by Saint Benedict of Nursia and other saints at Montecassino.Pope Leo XIII beatified him on 23 July 1887.

Prosopography of Anglo-Saxon England

The Prosopography of Anglo-Saxon England (PASE) is a database and associated website that aims to collate everything that was written in contemporary records about anyone who lived in Anglo-Saxon England, in a prosopography. The PASE online database presents details (which it calls factoids) of the lives of every recorded individual who lived in, or was closely connected with, Anglo-Saxon England from 597 to 1087, with specific citations to (and often quotations from) each primary source describing each factoid.

PASE was funded by the British Arts and Humanities Research Council from 2000 to 2008 as a major research project based at King's College London in the Department of History and the Centre for Computing in the Humanities, and at the Department of Anglo-Saxon, Norse and Celtic, University of Cambridge.The first phase of the project was launched at the British Academy on the 27 May 2005 and is freely available on the Internet at www.pase.ac.uk. A second phase (PASE2), released on 10 August 2010, added information drawn chiefly from the Domesday Book to the database.

Siege of Tudela

The Siege of Tudela was the main action of the French military campaign in Spain in 1087 in conjunction with Kings Alfonso VI of León and Castile and Sancho V of Navarre and Aragon. The arrival of a French army under Odo I, Duke of Burgundy, and William, Viscount of Melun, early in the spring of 1087 was a response to Alfonso's plea for military aid, which was generated by the offensive of the Almoravids on Iberia. After defeating Alfonso at the Battle of Sagrajas on 23 October 1086, the Almoravids retreated before the French could arrive. Alfonso then convinced his allies to direct their energies at Tudela, the northernmost fortress of the taifa of Zaragoza. The siege was a complete failure militarily, but several important negotiations took place there among the besieging parties.

Stigand of Selsey

Stigand (died 1087) was the last Bishop of Selsey, and first Bishop of Chichester.

USS Kirk

USS Kirk was a Knox-class destroyer escort, originally designated as DE-1087 and reclassified as a frigate, FF-1087 (1975), in the United States Navy. Her primary mission of ASW remained unchanged. She was named for Admiral Alan Goodrich Kirk.

Her contract was awarded to Avondale Marine on 25 August 1966. Kirk was laid down on 4 December 1970, launched on 25 September 1971 and commissioned on 9 September 1972.

William I, Count of Burgundy

William I (1020 – 12 November 1087), called the Great (le Grand or Tête Hardie, "the Stubborn"), was Count of Burgundy from 1057 to 1087 and Mâcon from 1078 to 1087. He was a son of Renaud I and Alice of Normandy, daughter of Richard II, Duke of Normandy. William was the father of several notable children, including Pope Callixtus II.

In 1057, he succeeded his father and reigned over a territory larger than that of the Franche-Comté itself. In 1087, he died in Besançon, Prince-Archbishopric of Besançon, Holy Roman Empire -- an independent city within the County of Burgundy. He was buried in Besançon's Cathedral of St John.

William married a woman named Stephanie (a.k.a. Etiennette).Children of Stephanie (order uncertain):

William the Conqueror

William I (c. 1028 – 9 September 1087), usually known as William the Conqueror and sometimes William the Bastard, was the first Norman King of England, reigning from 1066 until his death in 1087. A descendant of Rollo, he was Duke of Normandy from 1035 onward. After a long struggle to establish his power, by 1060 his hold on Normandy was secure, and he launched the Norman conquest of England six years later. The rest of his life was marked by struggles to consolidate his hold over England and his continental lands and by difficulties with his eldest son.

William was the son of the unmarried Robert I, Duke of Normandy, by Robert's mistress Herleva. His illegitimate status and his youth caused some difficulties for him after he succeeded his father, as did the anarchy that plagued the first years of his rule. During his childhood and adolescence, members of the Norman aristocracy battled each other, both for control of the child duke and for their own ends. In 1047 William was able to quash a rebellion and begin to establish his authority over the duchy, a process that was not complete until about 1060. His marriage in the 1050s to Matilda of Flanders provided him with a powerful ally in the neighbouring county of Flanders. By the time of his marriage, William was able to arrange the appointment of his supporters as bishops and abbots in the Norman church. His consolidation of power allowed him to expand his horizons, and by 1062 William secured control of the neighbouring county of Maine.

In the 1050s and early 1060s William became a contender for the throne of England, then held by the childless Edward the Confessor, his first cousin once removed. There were other potential claimants, including the powerful English earl Harold Godwinson, who was named the next king by Edward on the latter's deathbed in January 1066. William argued that Edward had previously promised the throne to him and that Harold had sworn to support William's claim. William built a large fleet and invaded England in September 1066, decisively defeating and killing Harold at the Battle of Hastings on 14 October 1066. After further military efforts William was crowned king on Christmas Day 1066, in London. He made arrangements for the governance of England in early 1067 before returning to Normandy. Several unsuccessful rebellions followed, and by 1075 William's hold on England was mostly secure, allowing him to spend the majority of the rest of his reign on the continent.

William's final years were marked by difficulties in his continental domains, troubles with his eldest son, and threatened invasions of England by the Danes. In 1086 William ordered the compilation of the Domesday Book, a survey listing all the landholdings in England along with their pre-Conquest and current holders. William died in September 1087 while leading a campaign in northern France, and was buried in Caen. His reign in England was marked by the construction of castles, the settling of a new Norman nobility on the land, and change in the composition of the English clergy. He did not try to integrate his various domains into one empire but instead continued to administer each part separately. William's lands were divided after his death: Normandy went to his eldest son, Robert Curthose, and his second surviving son, William Rufus, received England.


Ōtoku (応徳) was a Japanese era name (年号, nengō, "year name") after Eihō and before Kanji. This period spanned the years from February 1084 through April 1087. The reigning emperor was Emperor Shirakawa-tennō (白河天皇).
