Protectionism in the United States

Protectionism in the United States is protectionist economic policy that erects tariffs and other barriers on imported goods. This policy was most prevalent in the 19th century. At that time, it was mainly used to protect Northern industries and was opposed by Southern states that wanted free trade to expand cotton and other agricultural exports. Protectionist measures included tariffs and quotas on imported goods, along with subsidies and other means, to restrain the free movement of imported goods, thus encouraging local industry.

There was a general lessening of protectionist measures from the 1930s onwards, culminating in the free trade period that followed the Second World War. After the war, the United States promoted the General Agreement on Tariffs and Trade (GATT), to liberalize trade among all capitalist countries. In 1995, GATT became the World Trade Organization (WTO), and with the collapse of Communism its open markets/low tariff ideology became dominant worldwide. Protectionism has increased in popularity since the election of Donald Trump in 2016.
