10? Oct 1776 -	State of Connecticut [3][4]
7 Nov 1776	the style of public records is changed to "At a General Assembly of the Governor and Company of the State of Connecticut in New England in America," in accordance with a resolution adopted by the General Court or Assembly on 7 Nov 1776 (Connecticut State Records, 1:52)
12? Feb 1778	the delegates of Connecticut to the Continental Congress are authorized to agree to and ratify the Articles of Confederation and Perpetual Union, in accordance with a resolution adopted by the General Assembly on or after 12 Feb 1778 (Connecticut State Records, 1:532-533; Continental Congress Journals, 11:665) [1]
9 Jul 1778	the engrossed copy of the Articles of Confederation and Perpetual Union is ratified and signed by the delegates to the Continental Congress representing New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, Pennsylvania, Virginia, and South Carolina, at a session of the Congress held in Philadelphia, Pennsylvania, on 9 Jul 1778 (Continental Congress Journals, 11:677)
1 Mar 1781	Connecticut formed part of the United States upon the taking effect of the Articles of Confederation and Perpetual Union (Continental Congress Journals, 19:213-223)
15 Sep 1818	the Constitution of Civil Government for the People of the State of Connecticut is adopted at a session of the Convention held in Hartford on 15 Sep 1818, pending ratification by the people of Connecticut (Connecticut Convention Journal 1818, pp. 68-70)
12 Oct 1818	the Constitution of Civil Government for the People of the State of Connecticut is approved and ratified by the people at a vote held on 5 Oct 1818, the results of which are declared by proclamation of the Governor of Connecticut on 12 Oct 1818, thereby establishing the Constitution as the supreme law of the State (Connecticut Convention Journal 1818, p. 121)

The date of passage of this resolution, like that of most contemporary acts and resolves adopted by the General Assembly of Connecticut, cannot be determined with certainty, as such acts were typically dated as of the first day of the session, regardless of the actual day on which they were voted.
The status of the resolution was altered by An Act for confirming the Laws of this State as revised and amended, and for repealing such as are not contained in the foregoing Code, passed on or after 13 Jan 1784 by the General Assembly (Connecticut State Records, 5:281-282). A slightly edited version of this resolution was subsequently enacted as law under the title An Act containing an Abstract and Declaration of the Rights and Privileges of the People of this State, and securing the same (Connecticut Session Laws, 1784, pp. 1-2).
Occasional references to "State of Connecticut" instead of "(English) Colony of Connecticut" are found in some official documents issued between 4 Jul 1776 and 10 Oct 1776, including a proclamation of Governor dated 6 Sep 1776.
In early references: State of Connecticut, in New England, in America and State of Connecticut, in America.
