The Fordney–McCumber Tariff of 1922 was a law that raised American tariffs on many imported goods in order to protect factories and farms. Congress displayed a pro-business attitude in passing the tariff and in promoting foreign trade through providing huge loans to Europe, which in turn bought more American goods. The Roaring Twenties brought a period of sustained economic prosperity with an end to the Depression of 1920–21; the prosperity ended in late 1929, and the tariff was revised in 1930.
