The Medieval Kingdom of Bosnia existed from the 12th to the 15th centuries in the region of Southeast Europe. It was known for its unique blend of Catholic and Orthodox Christian influences, as well as the presence of Bosnian Church followers. The kingdom reached its peak under the rule of King Tvrtko I, who expanded its territory and established a strong central authority. The kingdom faced challenges from neighboring powers, including the Ottoman Empire and the Hungarian Kingdom. By the late 15th century, it fell under Ottoman control, marking the end of its independence. The legacy of the Medieval Kingdom of Bosnia continues to influence the cultural and historical identity of the region today.
