The Balts or Baltic peoples (Lithuanian: baltai, Latvian: balti) are a group of peoples inhabiting the eastern coast of the Baltic Sea who speak Baltic languages. Among the Baltic peoples are modern-day Lithuanians (including Samogitians) and Latvians (including Latgalians) — all East Balts — as well as the Old Prussians, Curonians, Sudovians, Skalvians, Yotvingians and Galindians — the Western Balts — whose languages and cultures are now extinct, but made a large influence on the living branches, especially on literary Lithuanian language.
The Balts are descended from a group of Proto-Indo-European tribes who settled the area between the lower Vistula and southeast shore of the Baltic Sea and upper Daugava and Dnieper rivers, and which over time became differentiated into West and East Balts. In the fifth century CE, parts of the eastern Baltic coast began to be settled by the ancestors of the Western Balts, whereas the East Balts lived in modern-day Belarus, Ukraine and Russia. In the first millennium CE, large migrations of the Balts occurred. By the 13th and 14th centuries, the East Balts shrank to the general area that the present-day Balts and Belarusians inhabit.
