Treaty of Tartu

The Treaty of Tartu, signed in 1920 between Finland and Soviet Russia, officially ended hostilities and established the borders between the two countries. It recognized Finland’s independence and defined its eastern boundary, which primarily followed the river Kymi and other landmarks. The treaty helped settle territorial disputes and fostered peaceful relations after Finland's independence from Russia in 1917. It remained in effect until the Soviet Union’s invasion of Finland during World War II. Overall, the treaty was crucial in securing Finland's sovereignty and creating a stable border in the early years of its independence.
