George Catlett Marshall Jr. (December 31, 1880 October 16, 1959) was an American army officer and statesman. He rose through the United States Army to become Chief of Staff of the US Army under Presidents Franklin D. Roosevelt and Harry S. Truman, then served as Secretary of State and Secretary of Defense under Truman. Winston Churchill lauded Marshall as the "organizer of victory" for his leadership of the Allied victory in World War II. After the war, he spent a frustrating year trying and failing to avoid the impending civil war in China. As Secretary of State, Marshall advocated a U.S. economic and political commitment to post-war European recovery, including the Marshall Plan that bore his name. In recognition of this work, he was awarded the Nobel Peace Prize in 1953.Born in Pennsylvania, Marshall graduated from the Virginia Military Institute (VMI) in 1901. Marshall received his commission as a second lieutenant of Infantry in February 1902 and immediately went to the Philippines. He served in the United States and overseas in positions of increasing rank and responsibility, including platoon leader and company commander in the Philippines during the PhilippineAmerican War. He was the Honor Graduate of his Infantry-Cavalry School Course in 1907, and graduated first in his 1908 Army Staff College class. In 1916 Marshall was assigned as aide-de-camp to J. Franklin Bell, the commander of the Western Department. After the nation entered World War I in 1917, Marshall served with Bell who commanded the Department of the East. He was assigned to the staff of the 1st Division; he assisted with the organization's mobilization and training in the United States, as well as planning of its combat operations in France. Subsequently, assigned to the staff of the American Expeditionary Forces headquarters, he was a key planner of American operations; including the Meuse-Argonne Offensive.

After the war, Marshall became an aide-de-camp to John J. Pershing, who was then the Army's Chief of Staff. Marshall later served on the Army staff, was the executive officer of the 15th Infantry Regiment in China, and was an instructor at the Army War College. In 1927, he became assistant commandant of the Army's Infantry School, where he modernized command and staff processes, which proved to be of major benefit during World War II. In 1932 and 1933 he commanded the 8th Infantry Regiment and Fort Screven, Georgia. Marshall commanded 5th Brigade, 3rd Infantry Division and Vancouver Barracks from 1936 to 1938; he received promotion to brigadier general. During this command, Marshall was also responsible for 35 Civilian Conservation Corps (CCC) camps in Oregon and Southern Washington. In July 1938, Marshall was assigned to the War Plans Division on the War Department staff; he later became the Army's Deputy Chief of Staff. When Chief of Staff Malin Craig retired in 1939, Marshall assumed the role of Chief of Staff in an acting capacity before his appointment to the position, which he held until the war's end in 1945.As Chief of Staff, Marshall organized the largest military expansion in U.S. history, and received promotion to five-star rank as General of the Army. Marshall coordinated Allied operations in Europe and the Pacific until the end of the war. In addition to accolades from Churchill and other Allied leaders, Time magazine named Marshall its Man of the Year for 1943 and 1947. Marshall retired from active service in 1945, but remained on active duty, as required for holders of five-star rank. From December 15, 1945, to January 1947, Marshall served as a special envoy to China in an unsuccessful effort to negotiate a coalition government between the Nationalists of Chiang Kai-shek and the Communists of Mao Zedong.

As Secretary of State from 1947 to 1949, Marshall advocated rebuilding Europe, a program that became known as the Marshall Plan, and which led to his being awarded the 1953 Nobel Peace Prize. After resigning as Secretary of State, Marshall served as chairman of the American Battle Monuments Commission and president of the American National Red Cross. As Secretary of Defense at the start of the Korean War, Marshall worked to restore the military's confidence and morale at the end of its post-World War II demobilization and then its initial buildup for combat in Korea and operations during the Cold War. After resigning as Defense Secretary, Marshall retired to his home in Virginia. He died in 1959 and was buried with honors at Arlington National Cemetery.

The Marshall Plan (officially the European Recovery Program, ERP) was an American initiative enacted in 1948 to provide foreign aid to Western Europe. The United States transferred over $13 billion (equivalent of about $115 billion in 2020) in economic recovery programs to Western European economies after the end of World War II. Replacing an earlier proposal for a Morgenthau Plan, it operated for four years beginning on April 3, 1948. The goals of the United States were to rebuild war-torn regions, remove trade barriers, modernize industry, improve European prosperity, and prevent the spread of communism. The Marshall Plan required a reduction of interstate barriers and the dissolution of many regulations while also encouraging an increase in productivity as well as the adoption of modern business procedures.The Marshall Plan aid was divided among the participant states roughly on a per capita basis. A larger amount was given to the major industrial powers, as the prevailing opinion was that their resuscitation was essential for the general European revival. Somewhat more aid per capita was also directed toward the Allied nations, with less for those that had been part of the Axis or remained neutral. The largest recipient of Marshall Plan money was the United Kingdom (receiving about 50% of the total), but the enormous cost that Britain incurred through the "Lend-Lease" scheme was not fully re-paid to the US until 2006. The next highest contributions went to France (8%) and West Germany (12%). Some eighteen European countries received Plan benefits. Although offered participation, the Soviet Union refused Plan benefits, and also blocked benefits to Eastern Bloc countries, such as Romania and Poland. The United States provided similar aid programs in Asia, but they were not part of the Marshall Plan.Its role in rapid recovery has been debated. The Marshall Plan's accounting reflects that aid accounted for about 3% of the combined national income of the recipient countries between 1948 and 1951, which means an increase in GDP growth of less than half a percent.After World War II, in 1947, industrialist Lewis H. Brown wrote (at the request of General Lucius D. Clay) A Report on Germany, which served as a detailed recommendation for the reconstruction of post-war Germany, and served as a basis for the Marshall Plan. The initiative was named after United States Secretary of State George C. Marshall. The plan had bipartisan support in Washington, where the Republicans controlled Congress and the Democrats controlled the White House with Harry S. Truman as president. The Plan was largely the creation of State Department officials, especially William L. Clayton and George F. Kennan, with help from the Brookings Institution, as requested by Senator Arthur Vandenberg, chairman of the United States Senate Committee on Foreign Relations. Marshall spoke of an urgent need to help the European recovery in his address at Harvard University in June 1947. The purpose of the Marshall Plan was to aid in the economic recovery of nations after World War II and secure US geopolitical influence over Western Europe. To combat the effects of the Marshall Plan, the USSR developed its own economic plan, known as the Molotov Plan, in spite of the fact that large amounts of resources from the Eastern Bloc countries were paid to the USSR as reparations for participating with the Axis Powers during the war.

The phrase "equivalent of the Marshall Plan" is often used to describe a proposed large-scale economic rescue program.In 1951 the Marshall Plan was largely replaced by the Mutual Security Act.
