Schoharie County is a county located in the U.S. state of New York. At the time of the 2010 census, the population was 32,749. It is part of the Albany-Schenectady-Troy Metropolitan Statistical Area. The county seat is Schoharie, a name that comes from a Mohawk Indian word meaning "floating driftwood."
When counties were established in New York State in 1683, the present Schoharie 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, Tryon County, contained the western portion (and thus, since no western boundary was specified, theoretically still extended west to the Pacific). The eastern boundary of Tryon County was approximately five miles west of the present city of Schenectady, and the county included the western part of the Adirondack Mountains and the area west of the West Branch of the Delaware River. The area then designated as Tryon County now includes 37 counties of New York State. The county was named for William Tryon, colonial governor of New York.
In the years prior to 1776, most of the Loyalists in Tryon County fled to Canada. In 1784, following the peace treaty that ended the American Revolutionary War, the name of Tryon County was changed to Montgomery County to honor the general, Richard Montgomery, who had captured several places in Canada and died attempting to capture the city of Quebec, replacing the name of the hated British governor. One of the prominent sites in the County is the Old Stone Fort, which was a fort used during the Revolution and the Civil War as an armory.
In 1789, Montgomery County was reduced in size by the splitting off of Ontario County from Montgomery. The actual area split off from Montgomery County was much larger than the present county, also including the present Allegany, Cattaraugus, Chautauqua, Erie, Genesee, Livingston, Monroe, Niagara, Orleans, Steuben, Wyoming, Yates, and part of Schuyler and Wayne Counties.
In 1795, Schoharie County was created by joining portions of Otsego County and Albany County.
The historic Middleburgh-Schoharie Railroad was situated in Schoharie County.
