Cold War: The Western occupying powers approve the Basic Law and establish a new German state, the Federal Republic of Germany.

The entirety of Germany was occupied and administered by the Allies of World War II, from the Berlin Declaration on 5 June 1945 to the establishment of West Germany on 23 May 1949. Unlike occupied Japan, Nazi Germany was stripped of its sovereignty and its government was entirely dissolved. After Germany formally surrendered on Tuesday, 8 May 1945, the four countries representing the Allies asserted joint authority and sovereignty through the Allied Control Council (ACC).

The Basic Law for the Federal Republic of Germany is the constitution of the Federal Republic of Germany.

West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. It is sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from 12 states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France.

May 23 is the 143rd day of the year in the Gregorian calendar; 222 days remain until the end of the year.
