1174–1177 Suzdalian war of succession

The Suzdalian war of succession of 1174–1177 was a war of succession in Vladimir-Suzdal (Suzdalia), a complex of principalities in the northeast of Kievan Rus'. The casus belli was the assassination of prince Andrey Bogolyubsky on 28 June 1174 by his own boyars. Immediately, his surviving step-brothers, son and nephews started fighting amongst themselves about who had the right to succeed him. The conflict would not be resolved until Vsevolod Yurievich "the Big Nest" had defeated his other brothers and his nephews, and seized power across Suzdalia in 1177.
