Expecting the upcoming defeat of the Serbian Despotate Đurađ Branković transferred all of his movable assets to Bečej before his death in 1456.

After the abolishment of this part of the Frontier in 1751, many Serbs from the town emigrated to Russia (notably to New Serbia and Slavo-Serbia).

To prevent this emigration, the Habsburg authorities formed the autonomous District of Potisje with seat in Bečej.

In the following period many Hungarians settled in Bečej (the first ones in 1757[7]) and gradually replaced the Serbs as the dominant ethnicity in the town.

[4] According to the 1910 census, the population of Becse municipality numbered 54,275 people, of whom 30,465 spoke Hungarian and 22,821 Serbian.

In 1918 Bečej became part of the Kingdom of Serbs, Croats and Slovenes and subsequent South Slavic states.
