2nd World War

The Second World War (1939-1945) was a global conflict involving many nations, primarily led by the Allies (including the U.S., UK, Soviet Union) against the Axis (mainly Germany, Japan, Italy). It was sparked by aggressive expansion, notably Nazi Germany’s invasion of Poland. The war resulted in massive destruction, loss of life, and atrocities, including the Holocaust. It ended with the Allies' victory, prompting the establishment of the United Nations and reshaping world politics. The conflict emphasized the importance of international cooperation to prevent future wars.
