Long ago, two big lands made a deal. 


In 1939, two powerful lands made a big deal. 

Germany and the Soviet Union agreed to split up Poland. 
One week after the deal, Germany invaded Poland. 
The Molotov–Ribbentrop Pact was a very important agreement from 1939. 

The pact worked through a secret plan. This plan was called a secret protocol. 
Before this deal, the two sides had many different relations. In the 1920s, Germany and the Soviet Union actually traded with each other. They even signed treaties in 1922 and 1926 to stay neutral. However, things changed when the Nazi Party rose to power.
Specific people signed the pact in Moscow on August 24, 1939. 


This pact changed the map of the world for a long time. Many lands like Estonia and Latvia became part of the Soviet Union. Some of these areas are part of Russia or Ukraine today. The agreement did not last until the ten years were up. On June 22, 1941, Germany launched Operation Barbarossa. 
The Molotov–Ribbentrop Pact was a major non-aggression treaty signed in 1939. 

Behind the public promise lay a secret mechanism called the Secret Additional Protocol. 
Before this pact, the relationship between Germany and the Soviet Union was very unstable. In the early 1920s, the two nations actually cooperated through the Treaty of Rapallo.
Diplomacy in the late 1930s failed to prevent the coming conflict. In 1938, Britain and France signed the Munich Agreement regarding Czechoslovakia.
On August 24, 1939, the pact was signed in Moscow. 

The pact led to rapid territorial changes across the region. In March 1940, the Soviet Union fought the Winter War against Finland. Following this, they annexed parts of Karelia, Salla, and Kuusamo. The Soviet Union also annexed Estonia, Latvia, Lithuania, and parts of Romania. Specifically, they took Bessarabia, Northern Bukovina, and the Hertsa region. Some of these actions, like the invasion of Bukovina, actually violated the original pact. These movements significantly shifted the political map of Eastern Europe.
Many of these territorial changes had lasting historical significance. The lands the Soviet Union took from Poland east of the Curzon line remained Soviet after the war.
