What was an effect of agreement made by the allies at the Potsdam w?

The Potsdam Agreement, reached in July-August 1945, resulted in the division of Germany into four occupation zones controlled by the United States, the Soviet Union, the United Kingdom, and France. This division aimed to demilitarize Germany and promote reconstruction, but it also sowed the seeds of tension between the Western Allies and the Soviet Union, ultimately leading to the Cold War. Additionally, the agreement outlined the principles for the prosecution of war criminals and set the stage for shifting borders in Eastern Europe, contributing to significant geopolitical changes in the post-war era.
