The end of the Second World War is a landmark in contemporary world politics. In 1945, the Allied Forces, led by the US, Soviet Union, Britain and France defeated the Axis Powers led by Germany, Italy and Japan, ending the Second World War (1939- 1945).

The world war ended when the United States dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki in August 1945, causing Japan to surrender

The western alliance was formalised into an organisation, the North Atlantic Treaty Organisation (NATO), which came into existence in April 1949. It was an association of twelve states which declared that an armed attack on any one of them in Europe or North America would be regarded as an attack on all of them. Each of these states would be obliged to help the other.

The eastern alliance, known as the Warsaw Pact, was led by the Soviet Union. It was created in 1955 and its principal function was to counter NATO’s forces in Europe
