Gleb Rostislavich of Ryazan

Gleb Rostislavich (died 30 June 1177) was prince of Ryazan and ancestor of its Rurikid branch, a son of Rostislav Yaroslavich. In 1145 his father sent him to rule Ryazan, but a Suzdalian siege drove him to the Polovtsians in 1146. He founded Glebov in 1159 and later secured Ryazan.

In 1176 he burned Moscow and sacked Bogolyubovo, but Vsevolod the Big Nest defeated him on the Koloksha in 1177, capturing him and his sons. Gleb died in prison at Vladimir after refusing freedom in exchange for Ryazan.
