John Albion Andrew was an American lawyer and politician from Massachusetts. He was elected in 1860 as the 25th Governor of Massachusetts, serving between 1861 and 1866, and led the state's contributions to the Union cause during the American Civil War (1861–1865). He was a guiding force behind the creation of some of the first African-American units in the United States Army, including the 54th Massachusetts Infantry. He belonged to the Whig, Free Soil, and Republican parties during his career.

The secretary of war was a member of the U.S. president's Cabinet, beginning with George Washington's administration. A similar position, called either "Secretary at War" or "Secretary of War", had been appointed to serve the Congress of the Confederation under the Articles of Confederation between 1781 and 1789. Benjamin Lincoln and later Henry Knox held the position. When Washington was inaugurated as the first President under the Constitution, he appointed Knox to continue serving as Secretary of War.

A militia is a military or paramilitary force that comprises civilian members, as opposed to a professional standing army of regular, full-time military personnel. Militias may be raised in times of need to support regular troops or serve as a pool of available manpower for regular forces to draw from.
