Stephen Kotroman

Stephen Kotroman was a vassal of the Hungarian king and ruled a portion of Bosnia from 1287 to 1316. He founded the Kotromanić dynasty, which ruled Bosnia from the late 13th to the mid-15th century. His son, Stephen Kotromanić, became the independent lord of all Bosnia in 1322, expanding the territory to include Hum and a stretch of the Adriatic coastline. His successor, Tvrtko I, further consolidated power, expanding Bosnia's lands and crowning himself king in 1377, making Bosnia the dominant South Slavic power. After Tvrtko I, dynastic disputes and foreign intervention weakened the state until it was incorporated into the Ottoman Empire in 1463.1
