Treniota

Treniota (also spelled Troniata; ; – 1264) was Grand Duke of Lithuania from 1263 to 1264.

Life Treniota was the nephew of Mindaugas, the first and only king of Lithuania. It is believed that Treniota was trusted to rule Samogitia.

Despite Mindaugas's conversion, the Teutonic Knights regularly made incursions in Lithuanian territory. After the Battle of Durbe in 1260, Treniota convinced Mindaugas to relapse from Christianity and attack the Teutonic Order, though the attack was ineffective and the Teutonic Knights were barely weakened. Mindaugas began to question his alliance with Treniota. However, before he was able act against his pagan nephew, Treniota together with Daumantas assassinated Mindaugas and two of his sons in 1263. Treniota usurped the throne and reverted the nation to paganism. However, he only ruled for a year before being deposed by Vaišvilkas, the younger son of Mindaugas.
