104 years ago today, on February 23, 1921 (January 16, 1921), the Soviet Navy launched a mutiny and was crushed by the Communist Party of the Soviet Union. From March 1918, the countries of Britain, France, the United States, and Japan, which were still engaged in the First World War, as well as their opponent Germany, sent troops to directly invade Soviet Russia and carry out direct armed attacks in an attempt to overthrow the Soviet regime. The domestic reactionary forces also rebelled one after another. The internal and external enemies launched attacks from all over the country, and soon occupied important regions such as Ukraine, the Urals, Siberia, and the Don Valley. The main producers of grain, coal, oil, and steel were under enemy control, and the Soviet state was in a very difficult situation. Lenin was also assassinated in August of that year and was shot twice. The policy of wartime communism was forced to be adopted under these extremely difficult conditions. In order to concentrate the only human and material resources available to defeat the enemy, the Soviet government implemented a temporary policy of "wartime communism" in 1918, which was collectively referred to as wartime communism. On February 23, 1921, Soviet naval personnel launched an anti-Bolshevik mutiny at the naval base on Kronstad Island, which was crushed by the Soviet Communist Party. This mutiny led to the adoption of Lenin's New Economic Policy. An important part of the New Economic Policy was the imposition of a grain tax instead of a surplus grain collection system. Farmers pay a certain grain tax according to state regulations, and the surplus grain in excess of the tax is owned by individuals, which greatly reduces the burden on farmers. In 1922, the government passed the Outline of the Land Ordinance, allowing peasants to use their land freely and to lease land and hire workers under Soviet supervision. The New Economic Policy ended early in 1929 and was replaced by large-scale industry, so it was implemented for eight years.
