<P> The Reconstruction Amendments are the Thirteenth , Fourteenth , and Fifteenth amendments to the United States Constitution , adopted between 1865 and 1870 , the five years immediately following the Civil War . The last time the Constitution had been amended was with the Twelfth Amendment more than 60 years earlier in 1804 . The Reconstruction amendments were important in implementing the Reconstruction of the American South after the war .
