Oliver P. Morton
American politician (1823–1877)

Oliver Hazard Perry Throck Morton (August 4, 1823 – November 1, 1877), commonly known as Oliver P. Morton, was a U.S. Republican Party politician from Indiana. He served as the 14th governor of Indiana during the American Civil War, and was a stalwart ally of President Abraham Lincoln.
Morton fought for equality and nationalism through the use of governmental power. His forceful pursuit of civil rights and prosecution of Copperheads and white supremacists gained him lasting enemies among the antiwar elements. Morton thwarted and neutralized the Democratic-controlled Indiana General Assembly. He exceeded his constitutional authority by calling out the militia without approval, and during the period of legislative suppression he privately financed the state government through unapproved federal and private loans. He was criticized for arresting and detaining political enemies and suspected southern sympathizers. As one of President Lincoln's "war governors", Morton made significant contributions to the war effort.
During his second term as governor, and after being partially paralyzed by a stroke, he was elected to serve in the U.S. Senate. He was a leader among the Radical Republicans of the Reconstruction era, and supported numerous bills designed to reform the former Southern Confederacy.
