The ancestors of the Croats in the Czech Republic arrived in the 1500s from central Croatia, fleeing before the Ottoman Turks. The period of their settling is at the same time as the arrival of the Croats to Austria, Hungary and Slovakia, who are called the Burgenland Croats.

They believed that the colonization of the Croats started from the Croatian regions south of the Kupa and Petrova Gora, better known as Banska Krajina [or today Banovina], was summarized by Adolf Turek.
