World Wars

The World Wars were two major global conflicts in the 20th century. World War I (1914-1918) began with tensions over territory, alliances, and nationalism, leading countries to fight primarily in Europe. World War II (1939-1945) was even larger, fueled by unresolved issues from WWI, economic hardships, and the rise of totalitarian regimes, resulting in widespread destruction worldwide. These wars involved many nations, caused immense loss of life, and reshaped global politics, economies, and borders. They highlighted the devastating costs of conflict and led to efforts for more peaceful international cooperation afterward.
