American women were granted the right to vote with the passage of the 19th amendment to the U.S. Constitution in 1920. During the early part of the century, agitation for equal suffrage was carried on by only a few individuals. The first of these was Frances Wright, a Scottish woman who came to the country in 1826 and advocated women's suffrage in an extensive series of lectures. In 1836 Ernestine Rose, a Polish woman, came to the country and carried on a similar campaign, so effectively that she obtained a personal hearing before the New York Legislature, though her petition bore only five signatures. At about the same time, in 1840, Lucretia Mott and Margaret Fuller became active in Boston, the latter being the author of the book The Great Lawsuit; Man vs. Woman. Efforts to gain various women's rights were subsequently led by women such as Susan B. Anthony, Virginia Minor, Elizabeth Cady Stanton, and Paulina Kellogg Wright Davis.
