What is "vytenis"

Vytenis (, Vićien') was the Grand Duke of Lithuania from c. 1295 to c. 1316. He became the first of the Gediminid dynasty to rule for a considerable amount of time. In the early 14th century his reputation outshone that of Gediminas, who is regarded by modern historians as one of the greatest Lithuanian rulers. The rule of Vytenis was marked by constant warfare in an effort to consolidate the Grand Duchy of Lithuania with the Ruthenians, Masovians, and the Teutonic Order.
