After World War II the old Prussian districts of Jerichow were changed. Some areas were given to the neighbouring districts of Havelberg, Rathenow, Brandenburg, Loburg and Zerbst. The two districts were also renamed after their chief town. Jerichow became Burg, and Jerichow II became Genthin. In 1952 the district of Burg was split into two parts, Loburg and Burg.
