The Congressional Union for Woman Suffrage was an American organization formed in 1913 led by Alice Paul and Lucy Burns to campaign for a constitutional amendment guaranteeing women's suffrage. It was inspired by the United Kingdom's suffragette movement, which Paul and Burns had taken part in. Their continuous campaigning drew attention from congressmen, and in 1914 they were successful in forcing the amendment onto the floor for the first time in decades.

Lucy Burns was an American suffragist and women's rights advocate. She was a passionate activist in the United States and the United Kingdom, who joined the militant suffragettes. Burns was a close friend of Alice Paul, and together they ultimately formed the National Woman's Party.
