CT: Individual County Chronologies

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. Rhode Island did not concede its claim to territory between the Pawcatuck River and Narragansett Bay (the Narragansett Country), but Connecticut quickly took control of the area. (Bowen, Disputes, 32; Swindler, 2:135-136)

Royal boundary commissioners decided the dispute over the Narragansett County by dismissing Massachusetts's claim and placing the area under royal jurisdiction. The area was named King's Province, and Rhode Island was given temporary administrative authority over it, pending a conclusive royal decision. Connecticut's claim to the area slipped into abeyance but was not abandoned until the boundary settlement of 12 May 1703. (Arnold, 1:315; James, 86-87; Potter, 178, 181)
