What group set out to make sure woman knew how to use their votes?

The National American Woman Suffrage Association (NAWSA) was instrumental in educating women about voting rights and ensuring they knew how to use their votes effectively. Formed in 1890, NAWSA focused on mobilizing women to advocate for their suffrage and provided resources to help them understand the voting process. Their efforts were crucial in raising awareness and empowering women in the lead-up to the ratification of the 19th Amendment in 1920.
