With the Greater Hamburg Act of 1937, the Hanseatic City of Lübeck and the Oldenburgian exclave Region of Lübeck were incorporated into the Schleswig-Holstein province, while a number of Hamburg's adjacent municipalities, among them the city districts of Altona and Wandsbek, were incorporated into the Hanseatic City of Hamburg.
Con la legge della "Grande Amburgo" del 1937, la città di Lubecca fu incorporata nella provincia, mentre le città di Altona e Wandsbek divennero distretti di Amburgo.
