Stephen Thomas of Bosnia

Stephen Thomas (Bosnian/Croatian: Stjepan Tomaš; Serbian: Стјепан Томаш Котроманић; ? – 10 July 1461) was King of Bosnia from 1443 until his death.

After the death of king Tvrtko II, Tomaš took the throne. He is known to have had a wife Vojača, a commoner he had promised to marry. After his enthronement, it became clear that she was unsuited to be a queen. Because of this he sought out Pope Eugene IV, who absolved the marriage and declared Thomas to be the legitimate king of Bosnia on 29 May 1445.

Thomas soon made peace with Stjepan Vukčić Kosača, a powerful noble ruling today's Herzegovina region. The king was now searching for a new wife, and decided to marry Vukčić's daughter Katarina Kosača, which brought some political stability to the kingdom. They were married on 26 May 1446 in Milodraža near Fojnica. The couple had three children: Catherine, Sigismund, and another son about whom very little is known.

Stephen Thomas died in 1461. He was succeeded by his son from his first marriage, Stephen Tomašević. Tomašević recognized Katarina as queen mother, and she continued to live at the royal dwellings at Bobovac and Kraljeva Sutjeska.
