Hildreth was born at Deerfield, Massachusetts. He was the son of Hosea Hildreth, who was a teacher of mathematics and later a Congregational minister. He attended Phillips Exeter Academy, starting in 1816, and staying for seven years thereafter. In 1826, he graduated from Harvard College. After studying law at Newburyport, he was admitted to the bar at Boston in 1830.
Career
In 1832, Hildreth he became joint founder and editor of a daily newspaper, the Boston Atlas. In 1834, he wrote a popular anti-slavery novel The Slave: or Memoir of Archy Moore. In 1837 he wrote for the Atlas a series of articles vigorously opposing the annexation of Texas. In the same year he published Banks, Banking, and Paper Currencies, a work which helped to promote the growth of the free banking systemin America. In 1838 he resumed his editorial duties on the Atlas, but in 1840 removed, on account of his health, to British Guiana, where he lived for three years and was editor of two weekly newspapers in succession at Georgetown. He published in this year a volume in opposition to slavery, Despotism in America. In 1849 he published the first three volumes of his History of the United States, two more volumes of which were published in 1851 and the sixth and last in 1852. The first three volumes of this history, his most important work, deal with the period 1492–1789, and the second three with the period 1789–1821. The history is notable for its painstaking accuracy and candor, as they are based on very careful analysis of the primary sources. The later volumes favor the Federalists. In dealing with the Jeffersonians, Hildreth calls them both "Republicans" and "Democrats" on the same page, but never "Democratic Republicans." Hildreth's Japan as It Was and Is was at the time a valuable digest of the information contained in other works on that country. He also wrote a campaign biography of William Henry Harrison ; Theory of Morals ; and Theory of Politics, as well as Lives of Atrocious Judges, compiled from Lord Campbell's two works. Between 1857 and 1860 Hildreth worked for the New York Tribune and during the same period he wrote several anti-slavery tracts for the fledgling Republican party under various pseudonyms. Poor health forced him to retire from his writing career in 1860. As a meed Massachusetts GovernorNathaniel Prentiss Banks and Senator Charles Sumner successfully lobbied for Hildreth's appointment as the United Statesconsul at Trieste in 1861. In 1865 he resigned from that position and moved to Florence, where he died on July 11, 1865. He is buried near Theodore Parker in the English Cemetery, Florence
