Women's suffrage in Missouri started in earnest after the Civil War.
Suffragists in Missouri held conventions, lobbied the Missouri General Assembly and challenged the Supreme Court of the United States (SCOTUS).
The case that went to SCOTUS in 1874, Minor v. Happersett was not ruled in the suffragists' favor.
Instead of challenging the courts for suffrage, Missouri suffragists continued to lobby for changes in legislation.
On July 3, 1919, Missouri becomes the eleventh state to ratify the Nineteenth Amendment.
