Andronikos Doukas (co-emperor)
Andronikos Doukas ( el, ), Latinized as Andronicus Ducas, was the third son of Byzantine emperor Constantine X Doukas (r. 1059–1067) and younger brother of Byzantine emperor Michael VII Doukas (r. 1071–1078). Unlike his other brothers, he was not named junior co-emperor by his father, and was raised to the dignity only by Romanos IV Diogenes (r. 1068–1071). He is otherwise relatively insignificant, and was not involved in the affairs of state to any degree. Biography Andronikos Doukas was born circa 1057, the third son of Constantine X Doukas and Eudokia Makrembolitissa. He studied under Michael Psellos, and several works survive that were compiled by the prominent scholars of the day to aid him in his studies: one treatise on geometry by Psellos and two philosophical essays by John Italos. Psellos also compiled a laudatory monody on Andronikos after the latter's death. Unlike his other two surviving brothers (the elder, the future Michael VII Doukas, and the younger Ko ...

List Of Byzantine Emperors
This is a list of the Byzantine emperors from the foundation of Constantinople in 330 AD, which marks the conventional start of the Byzantine Empire, Eastern Roman Empire, to Fall of Constantinople, its fall to the Ottoman Empire in 1453 AD. Only the emperors who were recognized as legitimate rulers and exercised sovereign authority are included, to the exclusion of junior co-emperors (''symbasileis'') who never attained the status of sole or senior ruler, as well as of the List of Byzantine usurpers, various usurpers or rebels who claimed the imperial title. The following list starts with Constantine the Great, the first Christian emperor, who rebuilt the city of Byzantium as an imperial capital, Constantinople, and who was regarded by the later emperors as the model ruler. It was under Constantine that the major characteristics of what is considered the Byzantine state emerged: a Roman polity centered at Constantinople and culturally dominated by the Greek East and Latin West, ...

Geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is called a '' geometer''. Until the 19th century, geometry was almost exclusively devoted to Euclidean geometry, which includes the notions of point, line, plane, distance, angle, surface, and curve, as fundamental concepts. During the 19th century several discoveries enlarged dramatically the scope of geometry. One of the oldest such discoveries is Carl Friedrich Gauss' ("remarkable theorem") that asserts roughly that the Gaussian curvature of a surface is independent from any specific embedding in a Euclidean space. This implies that surfaces can be studied ''intrinsically'', that is, as stand-alone spaces, and has been expanded into the theory of manifolds and Riemannian geometry. Later in the 19th century, it appeared that geom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Year Of Death Unknown
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doukid Dynasty
The House of Doukas, Latinized as Ducas ( el, Δούκας; feminine: Doukaina/Ducaena, Δούκαινα; plural: Doukai/Ducae, Δοῦκαι), from the Latin title ''dux'' ("leader", "general", Hellenized as 'ðouks'', is the name of a Byzantine Greek noble family, whose branches provided several notable generals and rulers to the Byzantine Empire in the 9th–11th centuries. A maternally-descended line, the Komnenodoukai, founded the Despotate of Epirus in the 13th century, with another branch ruling over Thessaly. The continuity of descent amongst the various branches of the original, middle Byzantine family is not clear, and historians generally recognize several distinct groups of Doukai based on their occurrence in the contemporary sources. Polemis, who compiled the only overview work on the bearers of the Doukas name, in view of this lack of genealogical continuity "it would be a mistake to view the groups of people designated by the ''cognomen'' of Doukas as forming on ...

11th-century Byzantine Emperors
The 11th century is the period from 1001 ( MI) through 1100 ( MC) in accordance with the Julian calendar, and the 1st century of the 2nd millennium. In the history of Europe, this period is considered the early part of the High Middle Ages. There was, after a brief ascendancy, a sudden decline of Byzantine power and a rise of Norman domination over much of Europe, along with the prominent role in Europe of notably influential popes. Christendom experienced a formal schism in this century which had been developing over previous centuries between the Latin West and Byzantine East, causing a split in its two largest denominations to this day: Roman Catholicism and Eastern Orthodoxy. In Song dynasty China and the classical Islamic world, this century marked the high point for both classical Chinese civilization, science and technology, and classical Islamic science, philosophy, technology and literature. Rival political factions at the Song dynasty court created strife among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1050s Births
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's College London
King's College London (informally King's or KCL) is a public research university located in London, England. King's was established by royal charter in 1829 under the patronage of King George IV and the Duke of Wellington. In 1836, King's became one of the two founding colleges of the University of London. It is one of the oldest university-level institutions in England. In the late 20th century, King's grew through a series of mergers, including with Queen Elizabeth College and Chelsea College of Science and Technology (in 1985), the Institute of Psychiatry (in 1997), the United Medical and Dental Schools of Guy's and St Thomas' Hospitals and the Florence Nightingale School of Nursing and Midwifery (in 1998). King's has five campuses: its historic Strand Campus in central London, three other Thames-side campuses (Guy's, St Thomas' and Waterloo) nearby and one in Denmark Hill in south London. It also has a presence in Shrivenham, Oxfordshire, for its profes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosopography Of The Byzantine World
The Prosopography of the Byzantine World (PBW) is a project to create a prosopographical database of individuals named in textual sources in the Byzantine Empire and surrounding areas in the period from 642 to 1265. The project is a collaboration between the British Academy and the Berlin-Brandenburg Academy of Sciences and Humanities. Origins The project was begun in the 1980s with the aim of completing the work on later Roman Empire and Byzantine prosopography begun by Theodore Mommsen in the 19th century and carried on by A.H.M. Jones and J. R. Martindale, which produced '' The Prosopography of the Later Roman Empire'' (three volumes, Cambridge, 1971–1992), covering the period from 260 (the accession of Gallienus) to 641 (the death of Heraclius, marking the end of late Antiquity). In 1993, the British Academy signed a collaboration agreement with the Berlin-Brandenburg Academy. The work is divided into three periods, 641–867 ( Heraclian dynasty to the Amorian dynas ...

Nikephoros Botaneiates
Nikephoros III Botaneiates, Latinized as Nicephorus III Botaniates ( el, Νικηφόρος Βοτανειάτης, 1002–1081), was Byzantine emperor from 7 January 1078 to 1 April 1081. He was born in 1002, and became a general during the reign of Byzantine Emperor Constantine IX Monomachos, serving in the Pecheneg revolt of 1048–1053. His actions in guiding his forces away from the Pechenegs following the Battle of Zygos Pass, in which they suffered eleven days of harassment before finally reaching the Byzantine city of Adrianople, attracted the attention of fellow officers, and he received the title of ''magistros'' as a reward. Nikephoros served in the revolt of Isaac I Komnenos against the Byzantine Emperor Michael VI Bringas, leading forces at the decisive Battle of Petroe. Under the Emperor Constantine X Doukas he was made '' doux'' of Thessalonica, where he remained until 1065, when he was reassigned as ''doux'' of Antioch. While ''doux'' of Antioch, he ...

Regency
A regent (from Latin : ruling, governing) is a person appointed to govern a state '' pro tempore'' (Latin: 'for the time being') because the monarch is a minor, absent, incapacitated or unable to discharge the powers and duties of the monarchy, or the throne is vacant and the new monarch has not yet been determined. One variation is in the Monarchy of Liechtenstein, where a competent monarch may choose to assign regency to their of-age heir, handing over the majority of their responsibilities to prepare the heir for future succession. The rule of a regent or regents is called a regency. A regent or regency council may be formed ''ad hoc'' or in accordance with a constitutional rule. ''Regent'' is sometimes a formal title granted to a monarch's most trusted advisor or personal assistant. If the regent is holding their position due to their position in the line of succession, the compound term '' prince regent'' is often used; if the regent of a minor is their mother, she would ...

Porphyrogennetos
Traditionally, born in the purple (sometimes "born to the purple") was a category of members of royal families born during the reign of their parent. This notion was later loosely expanded to include all children born of prominent or high-ranking parents. The parents must be prominent at the time of the child's birth so that the child is always in the spotlight and destined for a prominent role in life. A child born before the parents become prominent would not be "born in the purple". This color purple came to refer to Tyrian purple, restricted by law, custom, and the expense of creating it to royalty. ''Porphyrogénnētos'' ( el, Πορφυρογέννητος, , purple-born), Latinized as ''Porphyrogenitus'', was an honorific title in the Byzantine Empire given to a son, or daughter (, , Latinized ''Porphyrogenita''), born ''after'' the father had become emperor. Both imperial or Tyrian purple, a dye for cloth, and the purple stone porphyry were rare and expensive, and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
