The Bagratuni or Bagratid dynasty was an Armenian royal dynasty which ruled the medieval Kingdom of Armenia from c. 885 until 1045. Originating as vassals of the Kingdom of Armenia of antiquity, they rose to become the most prominent Armenian noble family during the period of Arab rule in Armenia, eventually establishing their own independent kingdom. Their domain included regions of Armenia such as Shirak, Bagrevand, Kogovit, Syunik, Lori, Vaspurakan, Vanand and Taron. Many historians, such as Cyril Toumanoff, Nicholas Adontz and Ronald Suny, consider them to be the progenitors of the Georgian royal Bagrationi dynasty.

Armenians are an ethnic group and nation native to the Armenian highlands of West Asia. Armenians constitute the main population of the Republic of Armenia and constituted the main population of the breakaway Republic of Artsakh until the 2023 Azerbaijani offensive in Nagorno-Karabakh and the subsequent flight of Nagorno-Karabakh Armenians. There is a wide-ranging diaspora of around five million people of full or partial Armenian ancestry living outside modern Armenia. The largest Armenian populations today exist in Russia, the United States, France, Georgia, Iran, Germany, Ukraine, Lebanon, Brazil, Argentina, Syria, and Turkey. The present-day Armenian diaspora was formed mainly as a result of the Armenian genocide with the exceptions of Iran, former Soviet states, and parts of the Levant.
