1930s.

Explanation:

The US pursued the policy of isolationism in two different times, but the most famous policy of isolationism occurred in the 1930s.

The first "isolationism" policy occurred in the during the 1914 - 1917, in which they did not take part militarily in World War I. However, this is not the well known policy of isolationism.

The well-known policy of isolationism started in the 1920s, and continued throughout the years until the 1930s, with the Attack of Pearl Harbor, December 7, 1941, that effectively ended the policy of Isolationism. This was because the US had a mixed-race population, in which different races wanted the US to join different sides. This led to the US believing that they should instead stay neutral, though most people were more Allied-sided. They joined the war in December 8, 1941, following the surprise attack, on the Allied side.
