Mamikonian Dynasty

The Mamikonians were a powerful clan group who were influential in Armenian political and military affairs from the 1st century BCE onwards. They rose to particular prominence from c. 428 CE to 652 CE in the half of Armenia ruled by the Sasanian Empire when marzpan viceroys represented the Persian king. One of the dynasty's most famous figures is Vardan Mamikonian who fell at the 451 CE Battle of Avarayr fought against Persia to defend Armenia's cultural and religious independence.

Fall of the Arsacid Dynasty

The Arsacid dynasty ruled Armenia from 12 CE and had managed to keep their balance on the diplomatic tightrope strung between the great powers of Rome and Persia for four centuries. By the 5th century CE, though, the Sasanian Empire had begun to expand its influence into areas previously contested between the two Empires. Armenia had already been formally divided between Persia and the Eastern Roman (Byzantine) Empire in 387 CE. The last Arsacid ruler was Artashes IV (r. 422-428 CE) as the Armenian crown, unable to repress the pro-Persian and anti-Christian factions at court, was abolished by Persia in their half of the country (sometimes referred to as Persarmenia). In 428 CE the marzpans were installed, a position which was higher than satraps and more akin to viceroys. Representing the Sasanian king, the marzpans had full civilian and military authority in Armenia and the system would not change until the mid-7th century CE.

The dynasty that now ruled the roost in Armenia was the Mamikonians whose heartlands were in the northern province of Tayk. Their earliest recorded member is Mancaeus who defended Tigranocerta in 69 BCE against Roman attacks. Long a powerful clan group, the Mamikonians had been particularly successful in the military thanks to their ability to raise cavalry forces of 3,000 knights. By the end of the 4th century CE the hereditary office of grand marshal (sparapet), who led the armed forces of Armenia, usually had a Mamikonian lord in the position. Amongst the other noble families the Mamikonians had been only second in importance to the Arsacid royal family itself, indeed two members had even served as regents: Mushegh and Manuel Mamikonian.

Once the ruling house of Arsacid fell, the Mamikonians were left to dominate both Armenian politics and military affairs within the limitations imposed by their Persian overlords. One of the most powerful early Mamikonian princes was Hamazasp, who married Sahakanyush, the daughter of the First Bishop Sakak c. 439 CE. The marriage unified the most prominent feudal and ecclesiastical families in Armenia and the vast territories of the Mamikonians with those of the descendants of Saint Gregory the Illuminator (d. c. 330 CE). Over the next three centuries, seven Mamikonian princes would rule Armenia.
