The first Lithuanian people were a branch of an ancient group known as the Balts. The main tribal divisions of the Balts were the West Baltic Old Prussians and Yotvingians, and the East Baltic Lithuanians and Latvians. The Balts spoke forms of the Indo-European languages. Today, the only remaining Baltic nationalities are the Lithuanians and Latvians, but there were more Baltic groups or tribes in the past. Some of these merged into Lithuanians and Latvians (Samogitians, Selonians, Curonians, Semigallians), while others no longer existed after they were conquered and assimilated by the State of the Teutonic Order (Old Prussians, Yotvingians, Sambians, Skalvians, and Galindians).
