The Dingley Tariff Act, enacted in 1897, was a significant piece of legislation in the United States that aimed to raise tariffs on imported goods. It was designed to protect American industries and workers by making foreign products more expensive, thereby encouraging consumers to buy domestic products. The act increased tariffs on a wide range of goods, including textiles, iron, and agricultural products. The Dingley Tariff Act replaced the previous Wilson-Gorman Tariff Act and marked a shift towards higher protective tariffs in U.S. trade policy. It was named after Nelson Dingley Jr., a congressman from Maine who played a key role in its passage. The act remained in effect until the Underwood Tariff Act of 1913, which aimed to reduce tariffs and implement a federal income tax.
