Lucy Burns and Alice Paul emerged as necessary leaders whose different methods helped transfer the Nineteenth Amendment forward. Shortly after the modification's adoption, Alice Paul and the National Woman's Party began work on the Equal Rights Amendment, which they believed was a obligatory further step towards equality. While women had the precise to vote in several of the pre-revolutionary colonies in what would turn into the United States, after 1776, with the exception of recent Jersey, all states adopted constitutions that denied voting rights to women. While suffrage bills had been introduced into many state legislatures during this interval, they were generally disregarded and few got here to a vote. While scattered movements and organizations dedicated to ladies's rights existed previously, the 1848 Seneca Falls Convention in New York is traditionally held as the beginning of the American girls's rights motion. Full girls's suffrage continued in Wyoming after it grew to become a state in 1890. Colorado granted partial voting rights that allowed girls to vote at school board elections in 1893 and Idaho granted ladies suffrage in 1896. Beginning with Washington in 1910, seven more western states passed women's suffrage laws, together with California in 1911, Oregon, Arizona, and Kansas in 1912, Alaska Territory in 1913, and Montana and Nevada in 1914. All states that have been successful in securing full voting rights for ladies earlier than 1920 have been located in the West.
