Bosnian Monarch. He was the illegitimate son of King Stijepan Tomas of Bosnia and a commoner named Vojaca. When King Stijepan Tomas was beheaded by the Turks, in 1461, King Stijepan Tomasevic was made king. He recognized his brother's wife Queen Katarina as Queen Mother and recognized the sucession of their children. Despite being the only Bosnian king ever to receive his crown from the Pope in Rome, King Stijepan Tomasevic did not long rule. Bosnia was under attack by the Ottoman Turks and the rest of Europe was in nearly as much disarray as Bosnia was. The Hungarians were not willing to aid Bosnia unless the Bosnian Heresy was stamped out and the Bosnians ceased paying any tribute to the Turks. They placed pressure on the Holy See over both these issues. The Serbs and nearly every other neighbor of Bosnia in the Balkans already were conquered. The Pope finally promised military aid, and then the Pope who promised this help died before any army could be raised and sent for Bosnia. These circumstances and the disunity of the Bosnian nobility sealed Bosnia's fate. In 1463, the Turks invaded. They were going to get the tribute or take the country. In that year Jace fell, after seven years of determined and clever resistance led by Petar Keglevic, d Kljuc fell next. While there is reasonable doubt that King Stijepan Tomasevic betrayed his father, it is fairly certain someone in the Bosnian camp betrayed King Stijepan Tomasevic. The children of King Stijepan Tomas and Queen Katarina were taken into captivity in 1463, sometime between 1474 and 1478, they were taken on the journey to Istanbul. Prince Sigismund, on becoming Muslim took the name Isak bey Kraljevic. Kraljevic means 'son of the king.' He became a Sandzak beg, in Karamania, married and had children. He was 14 years old at the time they were taken into captivity, the princess, Katarina was 10 years old at the time they were taken into captivity. Princess Katarina became ill during the journey and died in Skoplje. She was accorded burial in a turbe. This turbe was was in Gazi Baba municipality and was called 'Kral Kz'y Turbe' the 'King's daughter's turbe' it is mentioned as having been quite a beautiful example of Ottoman architecture, and having been much visited by local people. Sadly, it was destroyed in the terrible 1963 earthquake which devastated much of Skoplje. During the Bosnian war the church where the remains of King Stijepan Tomasevic were kept was utterly destroyed by shelling. Before this happened the Franciscans took the king's remains to Split, Croatia. The Bosnian government considered the removal illegal. After a number of formal requests by Bosnia-Herzegovina that the remains be returned, they were returned in September of 1999. The remains are now in Jace, Bosnia and Herzegovina.
