Answer:
The Smoot-Hawley Tariff Act
Step-by-step explanation:
The Smoot-Hawley Tariff Act is now widely blamed for worsening the severity of the Great Depression in the U.S. and around the world. Formally called the United States Tariff Act of 1930, the law is commonly referred to as the Smoot-Hawley Tariff or the Hawley-Smoot Tariff.
Among the suggested causes of the Great Depression are: the stock market crash of 1929; the collapse of world trade due to the Smoot-Hawley Tariff; government policies; bank failures and panics; and the collapse of the money supply.
