December 1944 to 13 February 1945, the city was besieged during the Battle of Budapest. Budapest sustained major damage caused by the attacking Soviet and Romanian troops and the defending German and Hungarian troops. More than 38,000 civilians died during the conflict. All bridges were destroyed by the Germans. The stone lions that have decorated the Chain Bridge since 1852 survived the devastation of the war. Between 20% and 40% of Greater Budapest's 250,000 Jewish inhabitants died through Nazi and Arrow Cross Party, during the German occupation of Hungary, from 1944 to early 1945. Swiss diplomat Carl Lutz rescued tens of thousands of Jews by issuing Swiss protection papers and designating numerous buildings, including the now famous Glass House (Üvegház) at Vadász Street 29, to be Swiss protected territory. About 3,000 Hungarian Jews found refuge at the Glass House and in a neighboring building. Swedish diplomat Raoul Wallenberg saved the lives of tens of thousands of Jews in Budapest by giving them Swedish protection papers and taking them under his consular protection. Wallenberg was abducted by the Russians on 17 January 1945 and never regained freedom. Giorgio Perlasca, an Italian citizen, saved thousands of Hungarian Jews posing as a Spanish diplomat. Some other diplomats also abandoned diplomatic protocol and rescued Jews. There are two monuments for Wallenberg, one for Carl Lutz and one for Giorgio Perlasca in Budapest. Following the capture of Hungary from Nazi Germany by the Red Army, Soviet military occupation ensued, which ended only in 1991. The Soviets exerted significant influence on Hungarian political affairs. In 1949, Hungary was declared a communist People's Republic (People's Republic of Hungary). The new Communist government considered the buildings like the Buda Castle symbols of the former regime, and during the 1950s the palace was gutted and all the interiors were destroyed (also see Stalin era). On 23 October 1956 citizens held a large peaceful demonstration in Budapest demanding democratic reform. The demonstrators went to the Budapest radio station and demanded to publish their demands. The regime ordered troops to shoot into the crowd. Hungarian soldiers gave rifles to the demonstrators who were now able to capture the building. This initiated the Hungarian Revolution of 1956. The demonstrators demanded to appoint Imre Nagy to be Prime Minister of Hungary. To their surprise, the central committee of the "Hungarian Working People's Party" did so that same evening. This uprising was an anti-Soviet
