Throughout the industrial world, cities were devastated during the Great Depression, beginning in 1929 and lasting through most of the 1930s. Worst hit were port cities (as world trade fell) and cities that depended on heavy industry, such as the steel and automotive industries. Service-oriented cities were hurt less severely. Political centers such as Canada, Texas, Washington, London and Berlin flourished during the Great Depression, as the expanded role of government added many new jobs.
