Administrative division of Polish territories during World War II can be divided into several phases, when territories of the Second Polish Republic were administered first by Nazi Germany (in the west) and Soviet Union (in the east), then (following German invasion of the Soviet Union) in their entirety by Nazi Germany and finally (following Soviet push westwards) by the Soviet Union again. Starting with the reform of 1946, the administrative division was returned to Poland (see Administrative division of People`s Republic of Poland).
