What took charge of reconstructing the south after the civil war

Johnson had a plan for Reconstruction (called Presidential Reconstruction) however the Radical Republicans really took charge. From 1867 to 1877, Radical Reconstruction plans included:
-Invalidation of state governments formed under Presidential Reconstruction
-Division of the South into 5 military districts, each governed by a Union General
-Ratification of the 14th and later the 15th amendments in each state
-Disqualification of former confederate officials from voting or holding political office.

Hope this helped! Let me know if there's another specific question you need in regards to the presidential or radical reconstruction plans.
