The Middle Ages in Romania began shortly after the withdrawal of the Roman legions from the former Roman province of Dacia in the late 3rd century and with the start of the Early Middle Ages and the Migration Period that followed afterwards respectively. It subsequently came to an end with the reign of Domn Michael the Brave (1593–1601) who managed, for a short time between 1599 and 1600, to rule Wallachia, Moldavia, and Transylvania together, the three principalities whose territories were to be united some three centuries later to form modern and contemporary Romania.
Zoltán, also Zolta, Zsolt, Solt or Zaltas is mentioned in the Gesta Hungarorum as the third Grand Prince of the Hungarians who succeeded his father Árpád around 907. Although modern historians tend to deny this report on his reign, because other chronicles do not list him among the Hungarian rulers, there is consensus that even if Zoltán never ascended the throne, all monarchs ruling in Hungary from the House of Árpád after around 955 were descended from him.
The King of Hungary was the ruling head of state of the Kingdom of Hungary from 1000 to 1918. The style of title "Apostolic King of Hungary" was endorsed by Pope Clement XIII in 1758 and used afterwards by all Monarchs of Hungary.
Gesta Hungarorum, or The Deeds of the Hungarians, is the earliest book about Hungarian history which has survived for posterity. Its genre is not chronicle, but gesta, meaning "deeds" or "acts", which is a medieval entertaining literature. It was written in Latin by an unidentified author who has traditionally been called Anonymus in scholarly works. According to most historians, the work was completed between around 1200 and 1230. The Gesta exists in a sole manuscript from the second part of the 13th century, which was for centuries held in Vienna. It is part of the collection of Széchényi National Library in Budapest.
Menumorut or Menumorout was the ruler of the lands between the rivers Mureș, Someș and Tisza at the time of the Hungarian conquest of the Carpathian Basin around 900, according to the Gesta Hungarorum, a Hungarian chronicle written after 1150 by an unidentified author, referred to as Anonymus. Historians debate whether Menumorut was an actual ruler or a fictional character created by the author, since the Gesta tells of multiple figures, including Menumorut, who are not identified in any other primary sources, and does not name any of the enemies of the invading Hungarians written of in other contemporary accounts of the invasion. According to Anonymus, Menumorut's duchy was populated primarily with Khazars and Székelys, and he acknowledged the suzerainty of the (unnamed) ruling Byzantine Emperor at the time.
Gelou was the Vlach ruler of Transylvania at the time of the Hungarian conquest of the Carpathian Basin around 900 AD, according to the Gesta Hungarorum. Although the Gesta Hungarorum, which was written after 1150, does not indicate the enemies of the conquering Hungarians (Magyars) known from earlier annals and chronicles, it refers to local rulers—including Gelou—who are not mentioned in other primary sources. Consequently, historians debate whether Gelou was a historical person or an imaginary figure created by the unidentified author of the Gesta Hungarorum. In Romanian historiography, based on the mention of him by Anonymus some 300 years later, Gelou is considered one of three early-10th-century Romanian dukes with lands in the intra-Carpathian region of present-day Romania.
Gyula was, according to Muslim and Byzantine sources, the title of one of the leaders, the second in rank, of the Hungarian tribal federation in the 9th–10th centuries. In the earliest Hungarian sources, the title name is only recorded as a personal name.
Ajtony, Ahtum or Achtum was an early-11th-century ruler in the territory now known as Banat in present Romania and Serbia. His primary source is the Long Life of Saint Gerard, a 14th-century hagiography. Ajtony was a powerful ruler who owned many horses, cattle and sheep and was baptised according to the Orthodox rite in Vidin. He taxed salt which was transferred to King Stephen I of Hungary on the Mureș River. The king sent Csanád, Ajtony's former commander-in-chief, against him at the head of a large army. Csanád defeated and killed Ajtony, occupying his realm. In the territory, at least one county and a Roman Catholic diocese were established.
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.
The Prince of Transylvania was the head of state of the Principality of Transylvania from the last decades of the 16th century until the middle of the 18th century. John Sigismund Zápolya was the first to adopt the title in 1570, but its use only became stable from 1576.
Transylvania is a historical region in central and northwestern Romania. It was under the rule of the Agathyrsi, part of the Dacian Kingdom, Roman Dacia (106–271), the Goths, the Hunnic Empire, the Kingdom of the Gepids, the Avar Khaganate, the Slavs, and the 9th century First Bulgarian Empire. During the late 9th century, Transylvania was reached and conquered by the Hungarian conquerors, and Gyula's family from seven chieftains of the Hungarians ruled Transylvania in the 10th century. King Stephen I of Hungary asserted his claim to rule all lands dominated by Hungarian lords, and he personally led his army against his maternal uncle Gyula III. Transylvania became part of the Kingdom of Hungary in 1002, and it belonged to the Lands of the Hungarian Crown until 1920.
The Eastern Hungarian Kingdom is a modern term coined by some historians to designate the realm of John Zápolya and his son John Sigismund Zápolya, who contested the claims of the House of Habsburg to rule the Kingdom of Hungary from 1526 to 1570. The Zápolyas ruled over an eastern part of Hungary, and the Habsburg kings ruled the west. The Habsburgs tried several times to unite all Hungary under their rule, but the Ottoman Empire prevented that by supporting the Eastern Hungarian Kingdom.
The history of the Székely people can be documented from the 12th century. According to medieval chronicles, the Székelys were descended from the Huns who settled in the Carpathian Basin in the 5th century. This theory was refuted by modern scholars, but no consensus view about the origin of the Székelys exists. They fought in the vanguard of the Hungarian army, implying that they had been a separate ethnic group, but their tongue does not show any trace of a language shift.
The Bulgarian–Hungarian wars were a series of conflicts that occurred during the 9th–14th centuries between the Bulgarian Empire and the Kingdom of Hungary. The nearly 500-year conflict encompassed the northern and western Balkans, or what is known today as north-western Serbia, Romania and northern Bulgaria.
The Voivode of Transylvania was the highest-ranking official in Transylvania within the Kingdom of Hungary from the 12th century to the 16th century. Appointed by the monarchs, the voivodes – themselves also the heads or ispáns of Fehér County – were the superiors of the ispáns of all the other counties in the province.
Gyula III, also Iula or Gyula the Younger, Geula or Gyla, was an early medieval ruler in Transylvania. Around 1003, he and his family were attacked, dispossessed and captured by King Stephen I of Hungary (1000/1001-1038). The name "Gyula" was also a title, the second highest rank in Hungarian tribal confederation.
The Transylvanian Diet was an important legislative, administrative and judicial body of the Principality of Transylvania between 1570 and 1867. The general assemblies of the Transylvanian noblemen and the joint assemblies of the representatives of the "Three Nations of Transylvania"—the noblemen, Székelys and Saxons—gave rise to its development. After the disintegration of the medieval Kingdom of Hungary in 1541, delegates from the counties of the eastern and northeastern territories of Hungary proper also attained the Transylvanian Diet, transforming it into a legal successor of the medieval Diets of Hungary.
The Count of the Székelys was the leader of the Hungarian-speaking Székelys in Transylvania, in the medieval Kingdom of Hungary. First mentioned in royal charters of the 13th century, the counts were the highest-ranking royal officials in Székely Land. From around 1320 to the second half of the 15th century, the counts' jurisdiction included four Transylvanian Saxon districts, in addition to the seven Székely seats.
The Duke of Transylvania was a title of nobility four times granted to a son or a brother of the Hungarian monarch. The dukes of the first and second creations, Béla (1226–1235) and Stephen of the Árpád dynasty were in fact viceroys with significant authority in Transylvania. The duke of the third creation, Louis, did not administer the province. The fourth duke, Stephen of the Anjou dynasty (1350–1351) did not play any significant role in politics.
Álmos, also Almos or Almus, was—according to the uniform account of Hungarian chronicles—the first head of the "loose federation" of the Hungarian tribes from around 850. Whether he was the sacred ruler (kende) of the Hungarians, or their military leader (gyula) is subject to scholarly debate. According to Constantine Porphyrogenitus, he accepted the Khazar khagan's suzerainty in the first decade of his reign, but the Hungarians acted independently of the Khazars from around 860. The 14th-century Illuminated Chronicle narrates that he was murdered in Transylvania at the beginning of the Hungarian conquest of the Carpathian Basin around 895.
