Protectionist tariffs did, in fact, play a role in the action of the Great Depression. Such policies, which were adopted by many countries during this time, contributed to a drastic contraction of international trade. For example, U.S. imports from Europe declined from a 1929 high of $1,334 million to just $390 million in 1932, while U.S. exports to Europe fell from $2,341 million in 1929 to $784 million in 1932. Overall, world trade declined by some 66% between 1929 and 1934. [0] https://history.state.gov/milestones/1921-1936/protectionism https://history.state.gov/milestones/1921-1936/protectionism
