By the late 19th century, most women had to work outside the home for wages due to financial necessity. Women worked as farm laborers, in factories, and in other emerging jobs in offices and schools. As more women entered the workforce and received education, they began advocating for reforms related to issues like temperance, child labor, and suffrage. Groups like the National Association of Colored Women and the National Women Suffrage Association were formed to promote women's rights and social reforms. The suffrage movement in particular employed a three-pronged strategy of lobbying state legislatures, pursuing legal challenges, and advocating for a constitutional amendment to secure women's right to vote nationally.
