Who ruled the south under the reconstruction act of 1867 until new state governments could be set up?

Under the Reconstruction Act of 1867, the South was ruled by military governors appointed by the federal government. This military rule was established to enforce order and oversee the transition to new state governments that would be formed under the terms of the Act. The aim was to ensure compliance with Federal Laws and protect the rights of newly freed African Americans during the Reconstruction period. This military oversight lasted until the southern states were readmitted to the Union and new governments were established.
