In 1430 it became part of the Kingdom of Hungary, and in 1456 it was victorious against Turks, when Christian Europe united in the city to put an end to the Siege of Belgrade. The golden age of the city continued into the 16th century. However, in 1521 the Turks conquered Belgrade. The population slowly started to decrease, as more and more colonists from Turkey poured into Belgrade, and its culture became a danger to the Porte. Serbian migrations began. In 1594, after a rebellion in Banat, many Serbs moved to the North and West, especially after the burning of St Sava's bones in the center of Belgrade by the Ottomans. Wars in today's northern Serbia, Hungary, Bosnia and Croatia encouraged many to start moving into those areas which were depopulated, as the Turkish influence was less intense in those areas. In the following century the Habsburg Empire took over most of these areas (except Bosnia), and the Serbian migration wave reached its peak in 1690 and 1737, when thousands of Serbs from Kosovo and South Serbia left their lands in hands of Muslims, moving north of the Danube into Christian Austria. The results of these migrations are still evident to this day, as Serbs became a majority in Vojvodina, much of western Bosnia, but also became a minority in Kosovo and Metohija and Sandzak. Novi Sad would resume the title of the Serbian capital of culture and liberty in following centuries, thriving in Austria while Belgrade entirely deteriorated under Turkey. Zemun (today's northern suburb of Belgrade) became home to hundreds of refugees from today's southern Belgrade.
