The Emergency Tariff Act of 1921 was a U.S. law aimed at protecting domestic industries from foreign competition. It was enacted in response to economic challenges following World War I, particularly the influx of imported goods that threatened American manufacturers. The act raised tariffs on various products, making foreign goods more expensive and encouraging consumers to buy American-made items. This legislation was part of a broader trend during the 1920s, where protectionist policies were favored to support the U.S. economy. The act was temporary and was intended to stabilize the market while the country adjusted to post-war economic conditions.
