Biography King David VII made Zakare, son of Shahnshah Zakarian, an escort for his journey to Karakorum, where Zakare attended on an official recognition of David by Güyük Khan. According to the 13th century historian Juvayni:

Siege of Baghdad (1258) Depiction of the Siege of Baghdad in Rashid al-Din's Jami al-tawarikh; the soldiers on the pontoons block the dawatdar from escaping down the Tigris. In 1258, Zakare participated in the Siege of Baghdad organized by Hulegu Khan, together with Prince Prosh Khaghbakian. They participated in the capture of the city and the massacre of its inhabitants, but the Christians were spared. According to Bar Hebraeus, the Georgians, who had been recognized warriors among the Mongols since the 1240s, 'especially effected a great slaughter'. From the Christian point of view, the conquest of Baghdad was considered as a "divine revenge" against the Caliphate.
