The document discusses major events from 1945-1991 including the Hungarian Revolution, the building of the Berlin Wall, and the end of the Cold War. The Hungarian Revolution occurred in 1956 when Hungarians rebelled against Soviet control. The Berlin Wall was constructed in 1961 to prevent East Berliners from escaping to West Berlin. By 1991, political reforms weakened Soviet control and led to the dissolution of the Soviet Union and end of the Cold War.
