The Temperance Movement, which had launched in the 1820s, gained its ultimate prize in 1919 with the 18th Amendment. Prohibition lasted almost fifteen years, but was eventually repealed by the 21st Amendment. Prohibition was the result of the political involvement of women, which also led to the Women’s Suffrage Movement and the 19th Amendment which put into the Constitution the requirement of all States to allow women to vote regardless of their sex. Shortly after that, in an effort to properly clarify and articulate the processes involved in the Presidential Election, and what should happen if a candidate dies or is not qualified, the 20th Amendment was proposed and ratified. Mr. Constitution, Douglas V. Gibbs, explains.
