The Articles of Confederation was the United States' first constitution. Proposed by the Continental Congress in 1777, it was not ratified until 1781.
Federalists felt that the Articles of Confederation were poorly written, and did not sufficiently act as they should have to function as this nations founding document. Led by â¦ James Madison the Federalists proposed to amend it, but ended up writing a totally different document the Constitution.
