On May 4, 1776, the Colony of Rhode Island and Providence Plantations was the first of the Thirteen Colonies to renounce its allegiance to the British Crown, and it was the fourth state to ratify the Articles of Confederation, doing so on February 9, 1778. The state boycotted the 1787 convention, which drew up the United States Constitution and initially refused to ratify it. It was thus the last of the original 13 states to do so, on May 29, 1790.
