James Madison’s birth on March 16, 1751, gets no attention as a federal or state holiday. Journalists usually mark the date with a week of festivities around the date, honoring Madison’s deep dedication to the principles of free press and open government, including his authoring and passing the First Amendment.
Madison’s chief notoriety comes from his work organizing the Philadelphia convention and working to ratify the U.S. Constitution — sometimes he’s called the Father of the Constitution. He also served as Secretary of State in Thomas Jefferson’s administration, and served two terms as President, including the War of 1812.
