855-856: After the death of his father Smbat, Ashot Metz (the Great) Bagratuni becomes Armenia’s main feudal lord. He accepts absolute supremacy of the Arabian caliphate and, with a series of skilful political manoeuvres, ensures that the country will not suffer further foreign invasions.

Subsequently, he is also appointed Governor of Georgia and of Albania and the title "prince of princes" is conferred upon him. 876: The Emperor Basil, in his condition as descendent of the Bagratids, sends ambassadors to the court of Ashot to ask the Armenian king for a crown and inviting him to take part in the coronation ceremony.
