The Lithuanians or Old East Lithuanians (Latin: Letwini; Low German: Lettowen; Old East Slavic: Литъва, Литва; Old Swedish: lättugha; modern Lithuanian: rytiniai senlietuviai, senlietuviai) were one of the largest East Baltic tribes, inhabiting present-day Eastern Lithuania in the 5th–13th centuries. Following the Northern Crusades, the ancient Lithuanians began gradually assimilating other neighbouring Baltic tribes, becoming the primary progenitor group of modern Lithuanians.
