The First Reconstruction Act divided the South into how many military districts?

In March 1867 the Congress passed a Reconstruction Act that imposed its desired version of reconstruction on the South. Ten former Confederate states were grouped into five military districts. Each district was ruled by a military governor provided with

large powers to compel those states to set up conventions to amend their constitutions as to properly conform with the Constitution of the United States, including the Fourteenth Amendment.

After those stages had been completed, the aforesaid states would have been readmitted to the Union as well as their representatives in the Federal Congress.
