List of Polish rulers

Poland was ruled by dukes (c.962–1025, 1032–1076, 1079–1295, 1296–1300 and 1306–1320) and kings (1025–1032, 1076–1079, 1295–1296, 1300–1305 and 1320–1795). The best-known dynasties are the Piast (c.962–1370) and Jagiellonian (1386–1572): intervening and subsequent monarchs were often rulers also of neighboring lands, or princes drawn from foreign dynasties. Polish kingship ended after the third Partition in 1795, and independence was restored on a republican basis in 1918.
