End of World War II in Europe - Wikipedia

On January 25, 1955, Russia ends state of war with Germany. From the article:

"End of state of war with Germany was declared by many former Western Allies in 1950. In the Petersberg Agreement of 22 November 1949, it was noted that the West German government wanted an end to the state of war, but the request could not be granted. The US state of war with Germany was being maintained for legal reasons, and though it was softened somewhat it was not suspended since "the US wants to retain a legal basis for keeping a US force in Western Germany".[36] At a meeting for the Foreign Ministers of France, the UK, and the US in New York from 12 September – 19 December 1950, it was stated that among other measures to strengthen West Germany's position in the Cold War that the western allies would "end by legislation the state of war with Germany".[37] In 1951, many former Western Allies did end their state of war with Germany: Australia (9 July), Canada, Italy, New Zealand, the Netherlands (26 July), South Africa, the United Kingdom (9 July), and the United States (19 October).[38][39][40][41][42][43] The state of war between Germany and the Soviet Union was ended in early 1955.[44]
