New York Counties
There are 62 counties in the State of New York. The first twelve counties in New York were created immediately after the British annexation of the Dutch colony of New Amsterdam, although two of these counties have since been abolished. The most recent county formation in New York was in 1912, when Bronx County was created from the portions of New York City that had been annexed from Westchester County. New York's counties are named for a variety of Native American words, British provinces, cities, and royalty, early American statesmen and generals, and state politicians.

County History

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.

The history of our nation was a prolonged struggle to define the relative roles and powers of our governments: federal, state, and local. And the names given the counties, our most locally based jurisdictions, reflects the "characteristic features of this country!"
