The Yalta and Tehran conferences were pivotal during World War II as they shaped the post-war world order.
At the Tehran Conference in 1943, the Allied leaders coordinated military strategies against the Axis powers and discussed plans for post-war reconstruction. The Yalta Conference in 1945 further solidified these plans, addressing the reorganization of Europe, the establishment of the United Nations, and the fate of Germany, which ultimately influenced the geopolitical landscape of the 20th century.
