when did the states ratify the 13th amendment
Thirteenth Amendment to the United States Constitution Having been ratified by the legislatures of three-fourths of the several states (27 of the 36 states, including those that had been in rebellion), Secretary of State Seward, on December 18, 1865, certified that the Thirteenth Amendment had become valid, to all intents and purposes, as a part of the Constitution.[78] Included on the enrolled list of ratifying states were the three ex-Confederate states that had given their assent, but with strings attached. Seward accepted their affirmative votes and brushed aside their interpretive declarations without comment, challenge or acknowledgment.[79]
Twenty-sixth Amendment to the United States Constitution On March 23, 1971, a proposal to lower the voting age to 18 years was adopted by both houses of Congress and sent to the states for ratification. The amendment became part of the Constitution on July 1, 1971, three months and eight days after the amendment was submitted to the states for ratification, making this amendment the quickest to be ratified.
