The Dingley Tariff was a U.S. law enacted in 1897 that raised tariffs on imported goods to protect American industries and promote domestic economic growth. This legislation followed the Wilson-Gorman Tariff and was designed to counteract the perceived negative effects of lower tariffs, making it one of the highest tariff rates in American history. The Dingley Tariff reflected the growing trend of protectionism during a time of rapid industrialization, helping to shape the economic landscape of the late 19th century.
