**Freedom Summer** was a campaign in the United States launched in June 1964 to attempt to register as many African-American voters as possible in Mississippi, which had historically excluded most blacks from voting.

The **Marshall Plan** was an American initiative to aid Europe, in which the United States gave economic support to help rebuild European economies after the end of World War II in order to prevent the spread of Soviet Communism.

The **Neutrality Acts** were passed by the United States Congress in the 1930s, in response to the growing turmoil in Europe and Asia that eventually led to World War II.
