Early medieval in the context of "List of Irish kingdoms"

King Arthur (Welsh: Brenin Arthur; Cornish: Arthur Gernow; Breton: Roue Arzhur; French: Roi Arthur) was a legendary king of Britain. He is a folk hero and a central figure in the medieval literary tradition known as the Matter of Britain.

In Welsh sources, Arthur is portrayed as a leader of the post-Roman Britons in battles against the Anglo-Saxons in the late-5th and early-6th centuries. He first appears in two early medieval historical sources, the Annales Cambriae and the Historia Brittonum, but these date to 300 years after he is supposed to have lived, and most historians who study the period do not consider him a historical figure. His name also occurs in early Welsh poetic sources, such as Y Gododdin. The character developed through Welsh mythology, appearing either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, and was sometimes associated with the Welsh otherworld Annwn.

Principality of Serbia (Modern Serbian: Кнежевина Србија / Kneževina Srbija; also known as Principality of Serbs, (Modern Serbian: Кнежевина Срба / Kneževina Srba; Latin: Principatum Serborum; Modern Greek: Πριγκιπάτο της Σερβίας) was one of the early medieval states of the Serbs, located in the western regions of Southeastern Europe. It existed from the 8th century up to c. 969–971 and was ruled by the Vlastimirović dynasty. Its first ruler known by name was Višeslav, who started ruling around 780, while by that time (starting from the years 680–681), the Bulgarian state had taken the lands to the east. Vlastimir resisted and defeated the Bulgarian army in a three-year-war (839–842), and the two powers lived in peace for some decades. Vlastimir's three sons succeeded in ruling Serbia together, although for a limited time; Serbia became a key part in the power struggle between the Byzantines and Bulgarians, predominantly allied with the Byzantines, which also resulted in major dynastic wars for a period of three decades. The principality was annexed in 924 by Simeon I and subjected to Bulgarian rule until 933 when Serbian prince Časlav was established as ruler of the Serbian land, becoming the most powerful ruler of the Vlastimirović dynasty.

An important process during this period was the Christianization of the Serbs, completed by the establishment of Christianity as state-religion in the second half of the 9th century. The principality was annexed by the Byzantines in c. 969–971 and ruled as the Catepanate of Ras. The main information of the history of the principality and Vlastimirović dynasty are recorded in the contemporary historical work De Administrando Imperio (written c. 948–949).

The Saxons, sometimes called the Old Saxons or Continental Saxons, were a Germanic people of early medieval "Old" Saxony (Latin: Antiqua Saxonia) which became a Carolingian "stem duchy" in 804, in what is now northern Germany, between the lower Rhine and Elbe rivers. Many of their neighbours were, like them, speakers of West Germanic dialects, including both the Franks and Thuringians to the south, and the coastal Frisians and Angles to the north who were among the peoples who were originally referred to as "Saxons" in the context of early raiding and settlements in Roman Britain and Gaul. To their east were Obotrites and other Slavic-speaking peoples.

The political history of these continental Saxons is unclear until the 8th century and the conflict between their semi-legendary hero Widukind and the Frankish emperor Charlemagne. They do not appear to have been politically united until the generations of conflict leading up to that defeat, before which they were reportedly ruled by regional "satraps". Previous Frankish rulers of Austrasia, both Merovingian and Carolingian, fought numerous campaigns against Saxons, both in the west near the Lippe, Ems and Weser, and further east, near Thuringia and Bohemia, including the area which later medieval sources referred to as "North Swabia". Charlemagne conquered all the Saxons after winning the long Saxon Wars (772–804 AD) and forced them to convert to Christianity, annexing Saxony into the Carolingian domain. Under the Carolingian Franks, Saxony became a single duchy, fitting it within the basic political structure of the later Holy Roman Empire. The early rulers of this Duchy of Saxony expanded their territories—and therefore those of the Holy Roman Empire—to the east, at the expense of Slavic-speaking Wends.

Northumbria (/nɔːrˈθʌmbriə/) was an early medieval kingdom in what is now Northern England and South Scotland.

The name derives from the Old English Norþanhymbre meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. What was to become Northumbria started as two kingdoms, Deira in the south and Bernicia in the north. Conflict in the first half of the seventh century ended with the murder of the last king of Deira in 651, and Northumbria was thereafter unified under Bernician kings.

Syriac Christianity (Syriac: ܡܫܝܚܝܘܬܐ ܣܘܪܝܝܬܐ, Mšiḥoyuṯo Suryoyto or Mšiḥāyūṯā Suryāytā) is a branch of Eastern Christianity of which formative theological writings and traditional liturgies are expressed in the Classical Syriac language, a variation of the old Aramaic language. In a wider sense, the term can also refer to Aramaic Christianity in general, thus encompassing all Christian traditions that are based on the liturgical uses of the Aramaic language and its variations, both historical and modern.

Along with Greek and Latin, Classical Syriac was one of the three most important languages of Early Christianity. It became a vessel for the development of a distinctive Syriac form of Christianity which flourished throughout the Near East and other parts of Asia during late antiquity and the early medieval period, giving rise to various liturgical and denominational traditions, represented in modern times by several churches which continue to uphold the religious and cultural heritage of Syriac Christianity.

This article lists some of the attested Gaelic kingdoms of early medieval Ireland prior to the Norman invasion of 1169-72.

For much of this period, the island was divided into numerous clan territories and kingdoms (known as túatha). These túatha often competed for control of resources and thus they continually grew and shrank (in both size and number). In addition to kingdoms or túatha, Gaelic Ireland was also divided into five prime overkingdoms (Old Irish cóiceda, Modern Irish cúige). These were Ulaid (in the north), Connacht (in the west), Laighin (in the southeast), Mumhan (in the south) and Mide (in the centre).
