The Tariff of 1816 was a protective tariff enacted by the United States Congress to support American industries after the War of 1812. It aimed to reduce competition from imported goods, particularly from European countries, by imposing higher duties on certain foreign products. This was intended to encourage domestic manufacturing and promote economic growth. The tariff primarily affected industries such as textiles and iron, which were vital to the nation's economy. By making imported goods more expensive, the government hoped to stimulate local production and create jobs. The Tariff of 1816 marked a significant shift in U.S. trade policy towards protectionism.
