James Gillespie Blaine (January 31, 1830 – January 27, 1893) was an American statesman and Republican politician who represented Maine in the United States House of Representatives from 1863 to 1876, served as Speaker of the House from 1869 to 1875, and was a U.S. senator from 1876 to 1881. He served twice as Secretary of State, under presidents James A. Garfield and Chester A. Arthur in 1881, and under Benjamin Harrison from 1889 to 1892. Blaine was one of two secretaries of state to serve under three presidents, the other being Daniel Webster. He sought the Republican presidential nomination in 1876 and 1880, and received the nomination in 1884, narrowly losing the general election to Democratic nominee Grover Cleveland. Blaine was a prominent figure in the moderate faction of the Republican Party, known as the "Half-Breeds".
Born in West Brownsville, Pennsylvania, Blaine moved to Maine after college, where he worked as a newspaper editor in Augusta before entering politics. Contemporary sources described him as an effective public speaker during an era when oratory was highly valued in American politics.
