'''Jefferson County''' is a [[county]] located in the [[U.S. state]] of [[New York]]. As of 2000, the population was 111,738. It is named after [[Thomas Jefferson]], third [[President of the United States of America]]. Its [[county seat]] is [[Watertown (city), New York|Watertown]].
When Jefferson County was created in [[1805]], it was named after the currently serving President, [[Thomas Jefferson]].
== History ==
When counties were established in New York State in [[1683]], the present Jefferson County was part of [[Albany County, New York|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, New York|Cumberland County]], and further on [[March 16]], [[1770]] by the creation of [[Gloucester County, New York|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, New York|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, New York|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, New York|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.
In [[1789]], the size of Montgomery County was reduced by the splitting off of [[Ontario County, New York|Ontario County]] from Montgomery. The actual area split off from Montgomery County was much larger than the present county, also including the present [[Allegany County, New York|Allegany]], [[Cattaraugus County, New York|Cattaraugus]], [[Chautauqua County, New York|Chautauqua]], [[Erie County, New York|Erie]], [[Genesee County, New York|Genesee]], [[Livingston County, New York|Livingston]], [[Monroe County, New York|Monroe]], [[Niagara County, New York|Niagara]], [[Orleans County, New York|Orleans]], [[Steuben County, New York|Steuben]], [[Wyoming County, New York|Wyoming]], [[Yates County, New York|Yates]], and part of [[Schuyler County, New York|Schuyler]] and [[Wayne County, New York|Wayne Counties]].
In [[1791]], Herkimer County was one of three counties split off from Montgomery (the other two being [[Otsego County, New York|Otsego]], and [[Tioga County, New York|Tioga County]]). This was much larger than the present county, however, and was reduced by a number of subsequent splits. The first one of these, in [[1794]], produced [[Onondaga County, New York|Onondaga County]]. This county was larger than the current Onondaga County, including the present [[Cayuga County, New York|Cayuga]], [[Cortland County, New York|Cortland]], and part of [[Oswego County, New York|Oswego Counties]].
[[Oneida County, New York|Oneida County]] (as well as a part of [[Chenango County, New York|Chenango County]]), was split off from Herkimer County in [[1798]].
Jefferson County was split off from Oneida County in [[1805]].
