Gediminas (c.1275 o December 1341) was Grand Duke of Lithuania from 1315 or 1316 until his death. He is credited with founding this political entity and expanding its territory which, at the time of his death, spanned the area ranging from the Baltic Sea to the Black Sea. Also seen as one of the most significant individuals in early Lithuanian history, he was responsible for both erecting the capital of Lithuania, and the establishment of a dynasty that can be traced to other European monarchies such as Poland, Hungary and Bohemia.
As part of his legacy, he obtained a reputation of being an inveterate pagan who diverted attempts in Christianizing his country to a political benefit against his enemies, after negotiations with the Pope and other Christian states
