Gedvydas

Gedvydas (or Edivid) (believed to have died ca. 1253) was one of the sons of Dausprungas and nephews of King of Lithuania Mindaugas. Gedvydas together with his brother Tautvilas and uncle Vykintas waged a civil war against Mindaugas. Gedvydas' brother and uncle were more active and Gedvydas played just a secondary role in the conflict. The war resulted in coronation of Mindaugas.

In 1248, Mindaugas sent Tautvilas, Gedvydas, and Vykintas to conquer Smolensk promising that they could keep what they would conquer. On the Protva River they defeated Duke of Moscow but near Zubtsov lost to the Duke of Vladimir-Suzdal. After discovering about the failure, Mindaugas took their land and property for himself. At the beginning of 1249, Tautvilas, Gedvydas, and Vykintas fled to Daniel of Halych, who was married to Gedvydas' sister. They formed a powerful coalition with the Samogitians, the Livonian Order, and Vasilko of Volhynia in opposition to Mindaugas. An internal war erupted. Daniel and the Livonian Order organized several military campaigns into Mindaugas lands.
