The town was first mentioned in a border agreement between Władysław Opolski, the duke of Opole and Racibórz and Ottokar II of Bohemia, in 1256 as Bogun. Historical documents regarding the first centuries of the town are scarce. 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 Bogumin 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. In 1624 only 138 permanent residents lived in the town. After defeating Maria Theresa of Austria during the Silesian Wars, King Frederick II of Prussia annexed most of Silesia, although Oderberg remained in Austrian Silesia. The town successively became part of the Austrian Empire and Austria-Hungary. After the Revolutions of 1848 in the Austrian Empire a modern municipal division was introduced in the re-established Austrian Silesia. The town became a seat of a legal district at first in Friedek and since 1868 in the Freistadt political district. At the end of the 19th century a wire and rolling mill was built by German industrialists from Berlin, Albert Hahn and Heinrich Eisner. In 1872 the important Kassa-Oderberg railway line was opened to traffic in a nearby Schönichel, which later outgrew Oderberg; this increased the town's importance and contributed to the Polish - Czechoslovak dispute over Cieszyn Silesia after World War I. According to the censuses conducted in 1880, 1890, 1900 and 1910 the population of the town grew from 1,839 in 1880 to 5,810 in 1910. The dominant language spoken colloquially shifted through the censuses. In 1880 and 1890 the majority were Polish-speakers, followed by German-speakers and Czech-speakers. In 1900 and 1910 the majority were German-speakers, followed by Polish-speakers and Czech-speakers. In terms of religion, in 1910 the majority were Roman Catholics, followed by Protestants, Jews and others. After the division of Cieszyn Silesia in 1920, the town became part of Czechoslovakia. Following the Munich Agreement, Bohumín and the Zaolzie region were annexed by Poland in October 1938. The town was then annexed by Nazi Germanyat the beginning of World War II. On 1 May 1945 Bohumín was taken by Soviet troops of the 1st Guards Army. After the war it was restored to Czechoslovakia and the remaining German population was expelled westward. There are few historical buildings remaining in Old Bohumín. It was always small with mostly wooden houses, which burnt down in frequent fires, as did the old town hall with its high tower. An old church still remains however; it was rebuilt in 1850 from its Gothic style to its current form. Another landmark is a tomb of the Henckels, former owners of Bohumín. The most important landmarks of New Bohumín are the Catholic Heart of Jesus Church from 1896; town hall from 1897–1898; complex of former German schools from 1894–1914; and the Lutheran church from 1901.
