The Ottoman conquest of Bosnia and Herzegovina was a process that started roughly in 1384, when the first Ottoman attacks on the Kingdom of Bosnia took place. In 1451, more than 65 years after its initial attacks, the Ottoman Empire officially established the Bosansko Krajište, an interim borderland military administrative unit, an Ottoman frontier, in parts of Bosnia and Herzegovina. In 1463, the Kingdom fell to the Ottomans, and this territory came under its firm control. Herzegovina fell to the Ottomans in 1482. It took another century for the western parts of today's Bosnia to succumb to Ottoman attacks, ending with the capture of Bihać in 1592.
