In order to help Europe recover from the war, the United States came up with the Marshall Plan. It is named after Secretary of State George Marshall. The Marshall Plan offered help and finances to European countries in order to recover from World War II.
Although the US had already been helping Europe to recover, the Marshall Plan made it official in 1948. Over the next four years the US gave $13 billion in assistance to Western European countries. The US also offered assistance to Russia and its allies, however, they turned it down.
By the time the Marshall Plan funding ended, all of the countries that participated had larger economies and were stronger than before the war. The plan was successful in helping Western Europe recover economically from the war.
