U.S. Legislation

Some expanded rights, others built safety nets, and a few — like the Emancipation Proclamation and Nineteenth Amendment — redefined who “We the People” truly includes. Together, they form the moral and legal backbone of the nation. Vote for the piece of legislation that left the biggest mark on American life — the moments when ideals became law.
