In Impeachment of a President, Hans L. Trefousse focuses on the causes of the failure to convict, the consequences of the acquittal, and the relationship of the impeachment to the ill success of Reconstruction. Drawing on a wealth of material, some only recently made available, Professor Trefousse sheds new light on the President's objectives and character.

Hans Trefousse (1921-2010) was Distinguished Professor of History at Brooklyn College and at the Graduate Center, of the City University of New York.
