Douglas MacArthur
Douglas MacArthur was an American general who commanded the United States army in the Pacific during World War II. After the war, he oversaw the American occupation of Japan and later led American troops in the Korean War. Though MacArthur pushed for total victory in the Korean War, seeking to conquer all of Korea and perhaps move into China, Harry S. Truman held him back from this aggressive goal. After a month of publicly denouncing the administration’s policy, MacArthur was relieved from duty in April 1951.

Macon’s Bill No. 2

James Madison
Fourth president of the United States (1809–1817). Madison began his political career as a Federalist, joining forces with Alexander Hamilton during the debate over the Constitution. He was one of the authors of The Federalist Papers and a staunch advocate of strong central government. Madison later became critical of excessive power in central government and left the Federalist Party to join Thomas Jefferson in leading the Republican Party.
Maine
U.S. battleship sunk by an explosion in Havana harbor in February 1898. Though later investigations suggested that an onboard fire had caused the blast, popular rumor was that the Spanish were responsible. The sinking of the Maine, combined with sensationalist news reports of Spanish atrocities, led the American public to push for war against Spain.
Manhattan Project
A secret American scientific initiative to develop the atomic bomb. Scientists worked for almost three years in Los Alamos, New Mexico, and on July 16, 1945 succeeded in detonating the first atomic blast. The bombs produced by the Manhattan Project were subsequently dropped on the Japanese cities of Hiroshima and Nagasaki at the end of World War II.
Manifest destiny
The belief of many Americans in the mid-nineteenth century that it was the nation’s destiny and duty to expand and conquer the West. Journalist John L.

Marbury v. Madison
In this 1803 case, Chief Justice John Marshall ruled that the Judiciary Act of 1789 was unconstitutional because Congress had overstepped its bounds in granting the Supreme Court the power to issue a writ of mandamus (an ultimatum from the court) to any officer of the United States. This ruling established the principle of judicial review.
March Against Death
In November 1969, 300,000 people marched in a long, circular path through Washington, D.C. for 40 hours straight, each holding a candle and the name of a soldier killed or a village destroyed in Vietnam. The march was a high point in the student antiwar movement and a poignant symbol of antiwar sentiment in the United States.
John Marshall
Chief Justice of the Supreme Court from 1801 until his death in 1835. Under Marshall’s leadership, the Court became as powerful a federal force as the executive and legislative branches. Marshall’s most notable decision came in the 1803 Marbury v. Madison case, in which he asserted the principle of judicial review. During James Monroe’s presidency, Marshall delivered two rulings that curtailed states’ rights and exposed the latent conflicts in the Era of Good Feelings.

McCulloch v. Maryland
1896 Supreme Court case that determined states could not tax federal institutions such as the Second Bank of the United States. The ruling asserted that the federal government wielded supreme power in its sphere and that no states could interfere with the exercise of federal powers. The ruling angered many Republicans, who favored states’ rights.
William McKinley

Mexican War
Tension between the U.S. and Mexico grew after Texas accepted Congress’s offer of admission to the Union despite the Mexican government’s opposition. In 1846, after Mexican troops crossed the Rio Grande, the U.S. declared war against Mexico. The U.S. won the war easily. The Treaty of Guadalupe Hidalgo ended the war and granted the U.S. possession of Texas, New Mexico, and California in exchange for $15 million.
