Andrey Bogolyubsky

Andrey I Yuryevich Bogolyubsky (Russian: Андрей Ю́рьевич Боголюбский, lit. 'Andrey Yuryevich of Bogolyubovo'; died 28 June 1174) was Prince of Vladimir-Suzdal from 1157 until his death. During repeated internecine wars between the princely clans, Andrey accompanied his father Yuri Dolgorukiy during a brief capture of Kiev in 1149. 20 years later, his son led the Sack of Kiev (1169). He was canonized as a saint in the Russian Orthodox Church in 1702.
