The Polish–Czechoslovak War, also called the Seven-Day War, was a brief conflict in late January 1919 over Cieszyn Silesia. Czechoslovak troops advanced against Polish forces to gain control of the region's coalfields and its railway, before the Allied powers imposed a ceasefire. In 1920 the Conference of Ambassadors divided the region along the Olza river.
