It was almost 100 years ago that Alice Paul and her fellow suffragists were arrested for picketing outside the White House for the right to vote. Today, women make up more than half of the electorate. For the first time in history, a woman is a major party’s presumptive presidential nominee.

As president of the National Association of Colored Women, Terrell supported the women’s suffrage movement, even picketing at the White House to demand equal treatment. After anti-discrimination laws were overturned in Washington in the 1890s, Terrell led a campaign to reinstate laws protecting African Americans. She continued to fight against segregation through boycotts and sit-ins. In 1953, the U.S. Supreme Court ruled that segregated eating places in Washington were unconstitutional.
