The Articles of Confederation was the United States' first constitution. Proposed by the Continental Congress in 1777, it was not ratified until 1781.
The Articles of Confederation became effective on March 1, 1781; after all thirteen states had ratified (approved) them. The Articles made the states and legislature (law making body)supreme. There was no executive branch (President). Judicial functions (courts) were very limited. The resulting government was weak. Efforts to make it stronger failed.
