Prussia (1701–1947)

Free State of Prussia

The kingdom that forged the German Empire in 1871 lost its crown in 1918 and lingered as a German state until the Allies formally abolished it in 1947 — erased by decree, not by war.

Prussia is the only major state ever abolished on paper — Allied Control Council Law No. 46 declared it 'ceased to exist' in a single page of text.
