Butvydas

Butvydas, also known as Pukuveras (died c. 1295), was Grand Duke of Lithuania from about 1290. First mentioned in 1289 making peace with Volhynia alongside his brother Grand Duke Butigeidis, he may have shared power before ruling alone after Butigeidis died.

His short reign was spent resisting annual Teutonic Order raids into Samogitia and fighting the Order's Polish allies in Masovia. He was the father of Grand Dukes Vytenis and Gediminas, who built Lithuania into a major power.
