Daumantas of Pskov

Daumantas or Dovmont (Russian: Довмонт, Belarusian: Даўмонт, Christian name Timothy (Russian: Тимофей), ; c. 1240? – May 17, 1299), was a Lithuanian princeling best remembered as a military leader of the Principality of Pskov between 1266 and 1299. During his term in office, Pskov became de facto independent from Novgorod.

He is venerated as a saint in the Orthodox Church with his feast day observed on May 20.

Until 1265, Daumantas was Duke of Nalšia, a northern province of the Grand Duchy of Lithuania, and was an ally of King Mindaugas. Mindaugas' and Daumantas' wives were sisters. In spite of the family relationship, Daumantas chose to ally himself with Mindaugas' nephew Treniota, who was Duke of Samogitia. Treniota had been steadily increasing his personal power within the kingdom as he tried to spark an all-Balts rebellion against the Teutonic Knights and the Livonian Order.

In 1263, Daumantas assassinated Mindaugas and two of his sons. It has been suggested that he acted in collusion with Treniota. As a result, the Grand Duchy of Lithuania relapsed into paganism for another one hundred and twenty years. Some Russian chronicles say that Daumantas' motive for the murder was to further his power and get revenge: after Queen Morta's death c. 1262, Mindaugas took Daumantas' wife for himself. When Mindaugas dispatched a large army towards Bryansk, Daumantas participated in the expedition, but suddenly returned and killed Mindaugas and two of his sons.
