I'm not sure if there was ever an "official" reconstruction period. Generally, "Reconstruction" is applied to federal government policies applied to defeated Southern states as early as 1863. Historians generally agree that Reconstruction policies ended soon after the inauguration (following a razor-thin election) of Rutherford B. Hayes in 1877.
The last of the thirteen colonies to be settled was Georgia.

The Reconstruction era ran from 1865 to 1877. Though in the long run, it really didn't work out.
