The Hungarian expansion (13th-15th c.)

At that time the Hungarian kingdom extended over a large territory, including a significant part of the Balkans, and subsequently uniting with Poland and Lithuania. The rule of the Hungarian Crown extended from the Baltic to the Adriatic Sea. The Hungarian kings established a highly centralized authority. While the German region of Europe was breaking up into small principalities in the late Middle Ages, a strong Hungarian empire was unfolding on the eastern side of Central Europe. Buda, the centre of the empire, was also a major urban settlement in political, as well as economic cultural terms.
