Answer:The Marshall Plan, also known as the European Recovery Program, was a U.S. program providing aid to Western Europe following the devastation of World War II. It was enacted in 1948 and provided more than $15 billion to help finance rebuilding efforts on the continent. The brainchild of U.S. Secretary of State George C. Marshall, for whom it was named, it was crafted as a four-year plan to reconstruct cities, industries and infrastructure heavily damaged during the war and to remove trade barriers between European neighbors—as well as foster commerce between those countries and the United States.
In addition to economic redevelopment, one of the stated goals of the Marshall Plan was to halt the spread communism on the European continent.
Implementation of the Marshall Plan has been cited as the beginning of the Cold War between the United States and its European allies and the Soviet Union, which had effectively taken control of much of central and eastern Europe and established its satellite republics as communist nations.
The Marshall Plan is also considered a key catalyst for the formation of the North Atlantic Treaty Organization (NATO), a military alliance between North American and European countries established in 1949.
