The 1860s saw significant constitutional activity due to the Civil War and Reconstruction era, specifically the 13th, 14th, and 15th amendments to the Constitution. Much of this activity was focused in the southern states, which were undergoing major political and social changes. The other options may have seen constitutional activity, but not to the same extent as the 1860s.
