In the early C16th the Ottoman's expanded their great Empire westward through Central Europe. After the Turkish victory at the Battle of Mohac in 1526, the Kingdom of Hungary was badly defeated and found itself divided into three separate parts. The territory that is present day Hungary was now under Turkish rule, while another part, Transylvania, became a Turkish protectorate vassal, controlled by the Ottoman Empire. That left only Slovakia, which managed to withstand the Turkish Invasion.
Slovakia now found itself the center of the Hungarian State. All important Hungarian political, administrative and religious institutions moved to Slovakia. Although, Slovakia had not felt the full force of the Turkish Invasion, as Hungary had done, its situation was about to change for the worse. No longer was the relationship with Hungary a 'tenant - landlord' one, the Turkish Invasion had forced the two very different peoples to be intertwined, which would eventually have dire consequences on Slovakia as a nation.
