How did suffrage change in the US in the nineteenth and twentith centeries?

In the nineteenth century, suffrage in the U.S. primarily expanded through the abolition of property requirements, allowing more white men to vote, and the Seneca Falls Convention of 1848, which highlighted women's rights. The passage of the 15th Amendment in 1870 aimed to secure voting rights for African American men, though many faced discriminatory barriers. In the twentieth century, the 19th Amendment, ratified in 1920, granted women the right to vote, marking a significant victory for the women's suffrage movement. Subsequent civil rights legislation in the 1960s further aimed to eliminate racial discrimination in voting, ensuring broader access for all citizens.
