The Pannonian Avars were an alliance of several groups of Eurasian nomads of various origins. The peoples were also known as the Obri in chronicles of Rus, the Abaroi or Varchonitai, or Pseudo-Avars in Byzantine sources, and the Apar to the Göktürks. They established the Avar Khaganate, which spanned the Pannonian Basin and considerable areas of Central and Eastern Europe from the late 6th to the early 9th century.
The Principality of Serbia 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 year 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 not for long; 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.
Great Moravia, or simply Moravia, was the first major state that was predominantly West Slavic to emerge in the area of Central Europe, possibly including territories which are today part of the Czech Republic, Slovakia, Hungary, Austria, Germany, Poland, Romania, Croatia, Serbia, Ukraine and Slovenia. The formations preceding it in these territories were the Samo's tribal union and the Pannonian Avar state.
Omurtag also known as Murtag or Murtagon was a Great Khan (Kanasubigi) of Bulgaria from 814 to 831. He is known as "the Builder".
The House of Vlastimirović was the first Serbian royal dynasty, named after Prince Vlastimir, who was recognized by the Byzantine Empire. The dynasty was established with the Unknown Archon, who ruled during the reign of Emperor Heraclius (610–641). The Vlastimirović dynasty ruled in Serbia until the 940s/960s, when some of the Serbian lands were annexed by the Byzantine Empire.
Glad was the ruler of Banat at the time of the Hungarian conquest of the Carpathian Basin around 900 AD, according to the Gesta Hungarorum. The Gesta, which was written by an author known in modern scholarship as Anonymus in the second half of the 12th century or in the early 13th century, is the earliest extant Hungarian chronicle. The Gesta did not refer to the enemies of the conquering Hungarians, who had been mentioned in earlier annals and chronicles, but wrote of a dozen persons, including Glad, who are unknown from other primary sources of the Hungarian Conquest. Therefore, modern historians debate whether Glad was an actual enemy of the conquerors or only a "fictitious person" made up by Anonymus. In Romanian historiography, based on the mention by Anonymus some 300 years later, Glad is described as one of the three Romanian dukes who ruled a historical region of present-day Romania in the early 10th century.
Mojmir I, Moimir I or Moymir I was the first known ruler of the Moravian Slavs (820s/830s–846) and eponym of the House of Mojmir. In modern scholarship, the creation of the early medieval state known as Great Moravia is attributed either to his or to his successors' expansionist policy. He was deposed in 846 by Louis the German, king of East Francia.
The Early Middle Ages in Romania started with the withdrawal of the Roman troops and administration from Dacia province in the 270s. In the next millennium a series of peoples, most of whom only controlled two or three of the nearly ten historical regions that now form Romania, arrived. During this period, society and culture underwent fundamental changes. Town life came to an end in Dacia with the Roman withdrawal, and in Scythia Minor – the other Roman province in the territory of present-day Romania – 400 years later. Fine vessels made on fast potter's wheels disappeared and hand-made pottery became dominant from the 450s. Burial rites changed more than once from cremation to inhumation and vice versa until inhumation became dominant by the end of the 10th century.
Vlastimir was the Serbian prince from c. 830 until c. 851. Little is known of his reign. He held Serbia during the growing threat posed by the neighbouring, hitherto peaceful, First Bulgarian Empire, which had expanded significantly toward Serbia.
The Braničevci were a South Slavic tribe that inhabited the region of Braničevo, in what is today Serbia, during the Middle Ages.
The Timočani were a medieval South Slavic tribe that lived in the territory of present-day eastern Serbia, west of the Timok River, as well as in the regions of Banat, Syrmia and Moesia Superior.
The March of Pannonia or Eastern March was a frontier march of the Carolingian Empire, named after the former Roman province of Pannonia and carved out of the preceding and larger Avar March.
The Avar March was a southeastern frontier province of the Frankish Empire, established after successful Frankish campaigns and conquests of Avarian territories along the river Danube, to the east from the river Enns, in what is today Lower Austria and northwestern Hungary. Since the Frankish conquest in the late 8th century, there were several administrative changes in those regions. Territory along the river Danube, from the river Enns to the Vienna Woods, was ruled directly, as a frontier extension (march) of the Frankish Bavaria, while regions further to the east, up to the river Rába, were initially designated to remaining Avarian princes, under the Frankish supreme rule. During the 820s and 830s, additional administrative changes were made in the wider region of Frankish Pannonia, inhabited mainly by Pannonian Slavs. Territories of the remaining Avarian princes were fully incorporated, and Avars eventually disappeared from the region.
The Guduscani or Goduscani were a tribe whose location and origin on the territory of early medieval Croatia remains a matter of dispute. According to different hypotheses, they were a tribe or clan of Croat, Slavic, Avaric or Gothic origin that was located around present-day Gacka (Lika), between upper Kupa River and the Dalmatian coast, or that were inhabitants around the river Guduča near the Bribir region.
Early Slavs settled in the eastern and southern parts of the former Roman province of Pannonia. The term Lower Pannonia was used to designate those areas of the Pannonian plain that lie to the east and south of the river Rába, with the division into Upper and Lower inherited from the Roman terminology.
Events from the 9th century in, or regarding, Historic Serbia or Serbs.
The Middle Ages in the Banat started around 900. Around that time, Duke Glad ruled Banat, according to the Gesta Hungarorum. Archaeological finds and 10th-century sources evidence that Magyars settled in the lowlands in the early 10th century, but the survival of Avar, Slav and Bulgar communities can also be documented. A local chieftain, Ajtony, converted to Eastern Orthodoxy around 1000, but his attempts to control the delivery of salt on the Mureș River brought him into conflict with Stephen I of Hungary. Ajtony died fighting against the royal army in the first decades of the 11th century. His realm was transformed into a county of the Kingdom of Hungary. Counties were the most prominent units of royal administration.
The Hungarian conquest of the Carpathian Basin, also known as the Hungarian conquest or the Hungarian land-taking, was a series of historical events ending with the settlement of the Hungarians in Central Europe in the late 9th and early 10th century. Before the arrival of the Hungarians, three early medieval powers, the First Bulgarian Empire, East Francia, and Moravia, had fought each other for control of the Carpathian Basin. They occasionally hired Hungarian horsemen as soldiers. Therefore, the Hungarians who dwelt on the Pontic-Caspian Steppe east of the Carpathian Mountains were familiar with what would become their homeland when their conquest started.
Alternative theories of the location of Great Moravia propose that the core territory of "Great Moravia", a 9th-century Slavic polity, was not located in the region of the northern Morava River. Moravia emerged after the fall of the Avar Khaganate in the early 9th century. It flourished during the reign of Svatopluk I in the second half of the century, but collapsed in the first decade of the 10th century. "Great Moravia" was regarded as an archetype of Czechoslovakia, the common state of the Czechs and Slovaks, in the 20th century, and its legacy is mentioned in the preamble to the Constitution of Slovakia.
The Avar Wars were fought between Francia and the Avar Khaganate in Central Europe from 788 to 803, and ended with the Frankish conquest of the khaganate's western regions. The first conflicts between the Avars and the Franks occurred in the 560s, shortly before the Avar conquest of the Pannonian Basin. Armed conflicts between the two powers were not unusual during the following centuries.
