Treaty of Tartu (Finland–Russia)

Okay buddy, so the Treaty of Tartu is like an agreement between two countries, Finland and Russia. It's kinda like when you and your friend make a deal about sharing your toy or something.

So a long time ago, Finland used to belong to Russia. But then, Finland got its independence, which means it's like a grown-up country that can make decisions on its own.

The Treaty of Tartu was signed in 1920, which means it happened a really long time ago. It was an agreement that said Finland and Russia would be good friends and not fight with each other anymore.

The treaty also said some important things about how Finland and Russia would share their land and water. For example, it said that Finland would get to keep some of its territory, and that the two countries would share a lake called Lake Saimaa.

So basically, the Treaty of Tartu was a very important agreement between Finland and Russia that helped them become better friends and share their land and water.
