Connecticut Colony

23 Apr 1662
King Charles II granted Connecticut a charter as a self-governing corporate colony, with an eastern boundary at Narragansett Bay, overlapping part of the Rhode Island patent.

Royal boundary commissioners decided the dispute over the Narragansett County by dismissing Massachusetts's claim and placing the area under royal jurisdiction.
