The Peace Treaty of Suwałki was signed on October 7, 1920, between the Polish Republic and the Soviet Union. This agreement marked the end of hostilities during the Polish-Soviet War, which had begun in 1919. The treaty established borders between the two nations and aimed to stabilize the region after years of conflict. The treaty was significant for both countries, as it allowed Poland to secure its eastern borders and gain recognition of its sovereignty. It also represented a temporary halt in the expansion of Soviet influence in Eastern Europe, shaping the geopolitical landscape of the region for years to come.
