During America's Age of Reconstruction, from Andrew Johnson (Lincoln's vice president) to Chester A. Arthur, the ruptured nation faced the difficult task of rebuilding a union after four years of civil war and a presidential assassination. This period was also known as the era of "The Ohio Generals"--three of the five presidents featured in this hour were generals in the Civil War, all from the state of Ohio. Defining moments include the impeachment trial of Andrew Johnson (by a margin of one, the Senate voted not to convict him), the triumphant ascendancy of Ulysses S. Grant, the back-room politics of Rutherford B. Hayes, the unrequited aspirations of James Garfield, and the civil service reforms of Chester A. Arthur.
