County QuickFacts: Census Bureau Quick Facts
When counties were established in New York State in 1683, the present Clinton County was part of Albany County. This
was an enormous county, including the northern part of New York State as well as all of the present State of Vermont
and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766 by the creation
of Cumberland County, and further on March 16, 1770, by the creation of Gloucester County, both containing territory now
in Vermont. On March 12, 1772, what was left of Albany County was split into three parts, one remaining under the name
Albany County. One of the other pieces, Charlotte County, contained the eastern portion.
In 1784, the name "Charlotte County" was changed to Washington County to honor George Washington, the American Revolutionary War general and later President of the United States of America.
In 1788, Clinton County was split off from Washington County. This was a much larger area than the present Clinton County, including several other counties or county parts of the present New York State.
In 1799, Essex County was split off from Clinton County.
In 1802, parts of Clinton, Herkimer, and Montgomery Counties were taken to form the new St. Lawrence County.
In 1808, Franklin County was split off from Clinton County.
Clinton County in the north easternmost corner of New York State bordering Canada on the north and Lake Champlain
on the east borders the great invasion route, the Kyber Pass of the North American Continent. This north-south
route: this depression in the Appalachian Chain between the rich coastal plain of the Atlantic Seaboard and the
arterial St Lawrence and Great Lakes giving access to the heart of the American Continent is just one half mile off
our shores. Geography predestines the history of an area and our geographical location has given our Clinton County
a heritage in historical events that shaped the early United States of America.
