King Louis II granted the town and château of Bohumín to George, Margrave of Brandenburg-Ansbach in 1523. The town began to develop during rule by the House of Hohenzollern, although further development of Bohumín was halted by frequent epidemics of bubonic plague and floodings of the Olza. It was officially known in German as Oderberg, and by the end of the 16th century the majority of citizens followed Protestantism. The successor after the Hohenzollerns in 1620 was Lazar Henckel, whose family of bankers and entrepreneurs hailed from Habsburg-ruled Hungary.
