This is the second part of a two-part documentary series on PBS's American Experience, focusing on Grant's presidency and his efforts to lead the nation through Reconstruction. It covers his presidency, which was marked by scandal due to his loyalty to associates, but also highlights his significant efforts to enforce civil rights, protect the rights of newly freed African Americans, and combat the Ku Klux Klan. The documentary examines his work to transform the nation from a union in conflict to a unified nation and his role in setting a course for America on the world stage.
