Granted in 1753 by the Masonian Proprietors, the town was named for Alexandria, Virginia, location of a 1755 conference of governors early in the French and Indian War. Alexandria was granted to Joseph Butterfield and others, March 13, 1757.^[4] First settled in 1769 by John Moore Corliss and his brother Jonathan, it was incorporated by the New Hampshire General Court on November 23, 1782.^[4] Danbury was set off and incorporated in 1795.

Although farmers found parts of the terrain mountainous, other parts were level intervales suited for cultivation. By 1859, when the population was 1,273, agriculture was a chief occupation. The town also had a carriage maker, nine sawmills and three gristmills.^[5]

Alexandria was the birthplace of Luther C. Ladd (1843–1861), the first enlisted soldier to lose his life in the Civil War, shot during the Baltimore Riot.
