William Thomas Hamilton (September 8, 1820October 26, 1888), a member of the United States Democratic Party, was the 38th Governor of Maryland in the United States from 1880 to 1884. He also served in the United States Senate, representing the State of Maryland, from 1868–1874, and in the House of Representatives, representing the second district (1849–1853) and fourth district (1853–1855) of Maryland. Early life and politics Hamilton was born in Boonsboro, Maryland, and received early schooling from a local tutor named John Brown. He went on to attend Hagerstown Academy, and later Jefferson College in Canonsburg, Pennsylvania, from 1836–1840. After college, Hamilton studied law with former Maryland Congressman John Thomson Mason, Jr., and was admitted to the bar in 1845. He then commenced law practice in Hagerstown, Maryland. In 1846, Hamilton was elected to the Maryland House of Delegates, but failed to win re-election in 1847. He was, however, elected as a Democrat to the Thirty-first, Thirty-second, and Thirty-third Congresses, serving from March 4, 1849 – March 3, 1855. While Hamilton was in Congress, even though his district was largely manufacturers and miners, he supported tariffs but only as a source of revenue for the government. Other actions while in Congress included his tenure as chairman of the Committee on the District of Columbia during the Thirty-third Congress. From 1855 until 1868, Hamilton avoided politics and resumed the practice of law and farming in Hagerstown. During that time, he became widely known throughout Western Maryland as an excellent trial lawyer. William Hamilton owned slaves and had a slaves quarters in his home in Hagerstown, Maryland. United States Senate After his long absence from politics, Hamilton was elected as a Democrat to the United States Senate by the General Assembly, and served from March 4, 1869, to March 3, 1875. Hamilton was a strong supporter of restoring southern sovereignty following the American Civil War, but voted against the Fifteenth Amendment to the United States Constitution which granted voting rights to all men regardless of race. In 1871, Hamilton endorsed William Pinkney Whyte during the Maryland governor campaign, but regretted the decision thereafter following Whyte's actions as governor. In 1874, Hamilton was abandoned by the state Democratic Party during the nomination process for his senate seat, and was not considered by them for re-election. Instead, Hamilton ran for governor in 1875, but lost his party's nomination to fellow Democrat John Lee Carroll.
