The 19th Amendment to the U.S. Constitution was ratified August 18,1920 giving women the constitutional right to vote.  Adding an amendment requires passage by two-thirds of each chamber of Congress, then ratification by three-fourths of the states, which in 1919 was 36 of the 48 states.

Alaska and Hawaii were still U.S. territories.  On May 21, 1918 the U.S. House of Representatives passed the language that would become the 19th Amendment.  It had passed in early 1918 but the Senate had not passed it.

The 19th Amendment to the U.S. Constitution says, "The right of citizens of the United States to vote shall not be denied or abridged by the United States or any state on account of sex."

My Mom and Dad always commented about their belief it is a citizen of the United States duty to exercise their voting rights.  Mom used to kid Dad she voted in all the elections to cancel his vote.  Their example though I believe carried on in their children.  I guess I can't speak for my siblings but I have voted in every election since becoming eligible.

July 28 Arkansas pushed the effort to one-third of the way home.

August 2 Montana and Nebraska joined the list.

Minnesota voted to ratify the 19th Amendment on September 8, 1919.  Minnesota women had first won the right to vote in school board elections in 1875.  The state saw growing membership in the Minnesota Woman Suffrage Association and Scandanavian Suffrage Association but were unable to win full suffrage until the 1919 vote.

January 16, 1920 Indiana, January 27th Wyoming joined the effort.  In 1868 the Wyoming Territorial Legislature passed a woman suffrage bill on a 13 to 6 vote.  Two years later lawmakers tried to get the bill repealed.  They passed a measure to repeal but the Governor vetoed it.  It became part of the new state's constitution in 1890.
