Answer:
- End of Civil War FIRST
 - The Civil War occurred before the reconstructions and was a 4 year war ending in May 1865
- Presidential Reconstruction SECOND
 - Andrew Johnson took over as President (he was the 17th) and laid out a plan for his changes to the new slavery views... These plans were known as a Presidential reconstruction. Pardons were granted to many.
- Radical Reconstruction THIRD
 - Radical Republicans started passing acts and changing views and politics during this time (1867 about).
- 13th, 14th, 15th Amendment FOURTH
 - Although the 13th amendment was before, the 14th and 15th occurred due to reconstructions I believe. This should be last.
