Due to restrictions imposed by the Treaty of Versailles, the Germans were not able to develop or sell any military equipment after World War I. In the post-war years, 7.92×57mm Mauser chambered Gewehr 98 pattern rifles were produced in Belgium, Czechoslovakia, Poland, Mexico, Austria and China. This, and the cartridge's high performance and versatility, led to the 7.92×57mm Mauser being adopted by the armed forces of various governments. These included: Spain, Poland, Czechoslovakia, Romania, Iran, Turkey, China, Egypt, Yugoslavia, former German African colonies. This made the round the most widely used military rifle cartridge in the world during the inter-war years.
