Butigeidis

Butigeidis (Budikid; Belarusian: Будзікід; died 1290 or 1291) was Grand Duke of Lithuania from 1285 to 1290 or 1291.

[2] He started his rule when the Livonian Order and the Teutonic Knights were finalizing their conquest of the Baltic tribes.

[2] In 1289 the Teutonic Knights built a castle in Tilsit and their raids intensified.

Lithuanians were forced to abandon Kolainių Castle located on the other bank of the Neman River.

[2] The castle system was further developed after his death and helped to resist the raids until the second half of the 14th century.
