The fourth day of May in each and every year is established, in this state, as a day for celebration of Rhode Island independence, being a just tribute to the memory of the members of our general assembly, who, on the fourth day of May, 1776, in the State House at Providence, passed an act renouncing allegiance of the colony to the British crown and by the provisions of that act declared Rhode Island sovereign and independent, the first official act of its kind by any of the thirteen (13) American colonies.
