Two World Wars

The Two World Wars were major global conflicts in the 20th century. World War I (1914-1918) involved many countries, primarily in Europe, and was sparked by political tensions and alliances. It ended with significant casualties and the Treaty of Versailles, which imposed harsh penalties on Germany. World War II (1939-1945) arose from unresolved issues from the first war, alongside the rise of dictatorships and expansionist policies. It was marked by widespread atrocities, including the Holocaust. The war ended with the defeat of the Axis powers and led to the creation of the United Nations, aiming to prevent future conflicts.
