Butigeidis

Butigeidis (died 1290 or 1291) was Grand Duke of Lithuania from 1285 and the first undisputed Gediminid ruler, taking power after Daumantas' death. He fought the Teutonic Order, which had recently overrun Suvalkija. In 1289 he led about eight thousand men against a Teutonic stronghold in Sambia.

Butigeidis was the first grand duke to fortify the Nemunas with a chain of castles. With his brother Butvydas he ceded Vawkavysk to Volhynia under a peace treaty, and Butvydas succeeded.
