Lesson
The Impeachment of Andrew Johnson
Guiding question
Was the impeachment of President Andrew Johnson a political tool?

When Andrew Johnson became President upon Lincoln’s assassination, he hoped to restore the Union according to a plan that would be lenient toward the South. Lacking congressional support and political skills, Johnson found himself in a show-down with Republicans in Congress who wanted to remake the South in the image of the North, raise up blacks and poor whites, and guarantee full civil and political rights for the freedmen. This clash of goals and strategies led to the first presidential impeachment trial in our history—a test of the constitutional principles of separation of powers and checks and balances. In the end, the Founders’ mechanism of three co-equal branches of government proved strong enough to resolve the crisis.
