After the war, the street became part of the Soviet-occupied sector of Berlin. The Soviet Military Administration had it renamed Liebknechtstraße in 1947 for Karl Liebknecht, co-founder of the German Communist Party. Liebknecht had his lawyer's office nearby and during the German Revolution of 1918–19 had proclaimed a "Free Socialist Republic" at the City Palace on 9 November 1918, shortly before he was murdered by "Freikorps" paramilitaries. The bridge to Spree Island was rebuilt in a simple form in 1949/50 and equally named Liebknecht Bridge.
