World War II
NATO formation refers to the establishment of the North Atlantic Treaty Organization in 1949 as a military alliance among Western nations aimed at countering the threat posed by the Soviet Union during the early Cold War. The formation of NATO was a pivotal moment in the rebuilding of Europe, as it not only provided a collective defense mechanism for member states but also solidified the division between the Western bloc and the Eastern bloc, influenced by the geopolitical landscape shaped by World War II and the Marshall Plan.
