Fall of Bosnian Kingdom
As the Ottoman conquest of Europe started in late 14th century, they would be taking over all of the Balkan territories, eventually reaching Basnian state. That occurred during the rule of Stephen Thomas and Catherine of Bosnia. King Thomas passed away in 1461 leaving queen Catherine as 37 year old widow with two minor children.
Successor to the throne was Stephen Tomasevic, her stepson. During the king Thomas’s lifetime their relationship wasn’t so good which influenced mostly their relation after Thomas’s death. However this weakened the strength and the influence of the kingdom in the most critical time. While the Ottoman conquest was arriving to the balkan.
In this period King Stephen Tomasevic lost all of his allies as they betrayed him and left him to defend from the Ottomans by himself. Bosnia fell under the rule of the Ottomans in 1463 and became westernmost province of Ottoman Empire. Province of Herzegovina was able to prolong their fall until the 1482. After the fall of the Kingdom Catherine of Bosnia escaped to city of Dubrovnik. Her final destination was Rome which she would be reaching in 1467.
During her time in Rome there were several attempts to revive the kingdom of Bosnia. She governed with kings in region but none of them saw the benefit in opposing mighty Ottoman Empire.
