At one time Connecticut (third-smallest state in area) was fixing to become the third-largest. In 1662 King Charles II granted a charter to the Connecticut colony that extended between 41° and 42°2′ N latitude clear out to the Pacific Ocean.
If that had gone through, I figure dimensions of 72 miles (116 km) north to south, by ~2600 miles (~4200 km) east to west (let me know if my rough measurements are too inaccurate) makes for a claimed western area of ~187,200 square miles (~487 200 km[sup]2[/sup]). This added to the state’s actual area of 5,544 square miles (14,371 km²) would have made a grand total of roughly 193,000 square miles (~500,000 km[sup]2[/sup]). Compare this to Alaska at 663,267 mi² (1 717 854 km²) and Texas at 268,820 mi² (696 241 km²). The full western extent of Connecticut’s charter (not counting the triangular chunk that New York took out of it) was going to be about 35 times bigger than the actual size of Connecticut.
If that had gone through, places that would now be in Connecticut include
Wilkes-Barre, PA
Cleveland, OH
Niles, MI
South Bend, IN
Chicago, IL
Des Moines, IA
Omaha, NE
Cheyenne, WY (note the name Wyoming in what follows)
Paradise Valley, NV
Eureka, CA
They actually got the first two places on the list… briefly.
In the 1760s Connecticut was a small colony, with a growing population and poor soil. I guess it seemed a no-brainer for them to settle people in their western claim, where there was plenty of good land. Once they leapfrogged New York, the first nice place to settle they found in Western Connecticut was the Wyoming Valley. Soon Wilkes-Barre and the other Yankee settlements around it acceded themselves to Connecticut. At first it was part of Litchfield County and then formed its own county called Westmoreland.
Unfortunately, King Charles had also granted William Pitt a charter in 1682 that extended Pennsylvania north into the same territory. Methinks Your Majesty did like totally space it out, dude. Both colonies purchased the same land from the Indians. Connecticut and Pennsylvania actually fought a series of little wars (1769-71, 1775, and 1784) over the Wyoming Valley. As as result of the dispute, the Yankee side tried to establish the new State of Westmoreland in 1783, but gave up the idea after a few months. Finally, in 1786 or 1787 (sources differ), Connecticut ceded its western claims to the federal government as part of the [state cessions deal by which states ceded their trans-Appalachian claims in exchange for the federal government assuming their debts. The Wikipedia article on state cessions says that Connecticut ceded its western lands as far as the Mississippi. I still haven’t found out what happened to the rest of their land grant that supposedly extended to California. They probably just quietly dropped the idea when they realized it could never work, given the dimensions of the continent. The area from Long Island Sound to Pacific Ocean is about 38 times longer than it is wide.
So as a consolation prize for losing the Wyoming Valley, Connecticut’s Plan B was to leapfrog Pennsylvania and settle the next chunk of land to the west. This is how the [url=http://en.wikipedia.org/wiki/Connecticut_Western_Reserve]Western Reserve](]http://en.wikipedia.org/wiki/State_cessions[/url) came to be: the land of my birth. The Connecticut Land Company bought the Western Reserve from the state and sent Moses Cleaveland there with a party of surveyors and a few settlers in 1796, which is how Cleveland got to be there.
In 1792 the Connecticut legislature set aside the western end of the Western Reserve as land for people in several Connecticut towns whose homes were torched by the Redcoats during the Revolution. The area is known as the [url=]Firelands. Thirty years later, a very few of those folks or their heirs had actually moved out there. This explains the transplanted names of those burnt towns way out in the middle of northern Ohio: Norwalk, New Haven, North Fairfield, New London, Danbury Township, Greenwich, Willard. When I was young my maternal grandparents lived in the Firelands, in Sandusky and we often visited. So as far as I can tell, that was the farthest west any of the original 13 states reached in realizing their western claims.
