When counties were established in theProvince of New York in 1683, the present Broome County was part of the enormousAlbany County, including the northern part of New York State as well as all of the present State ofVermont and, in theory, extending westward to the Pacific Ocean. This county was reduced in size on July 3, 1766, by the creation ofCumberland County, and further on March 16, 1770, by the creation ofGloucester 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 ofSchenectady, and the county included the western part of theAdirondack Mountains and the area west of the West Branch of theDelaware River. The area then designated as Tryon County now is organized as 37 counties of New York State. The county was named forWilliam 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 theAmerican Revolutionary War, the name of Tryon County was changed toMontgomery County, for GeneralRichard Montgomery, who had captured several places in Canada and died attempting to capture the city ofQuebec, thus replacing the name of the hated British governor.
On March 28, 1806, Broome County was formed by splitting several towns off from Tioga County.[3] At the time, this included all of Broome County's current area, as well as the then-namedtown of Tioga (renamed the town of Owego in 1813) and thetown of Berkshire. Small portions of land were lost toCortland County andTompkins County in 1815 and 1817, respectively.[4] The towns of Owego and Berkshire were returned to Tioga County on March 21, 1822, establishing the present-day boundaries of Broome County.[4][5]

Broome County lies on the southern line of New York. Its southern border abuts the northern boundary of the state ofPennsylvania. TheSusquehanna River flows southward through the eastern part of the county, entersSusquehanna County in Pennsylvania, then re-enters Broome and flows northwestward to meet theChenango River at Binghamton. The combined flow moves west-southwestward intoTioga County to the west. TheWest Branch Delaware River flows southward along the lower portion of the county's east border, delineating that portion of the border between Broome andDelaware counties.[6]
The county's western portion is hilly, with wide valleys that accommodate Binghamton and its suburbs. In the northern portion,Interstate 81 traverses a wideglacial valley. The eastern part of the county is much more rugged, as the land rises to theCatskill Mountains. The terrain generally slopes to the west.[7] The county's highest point is in the southeast of the county, aU.S. National Geodetic Surveybenchmark known as Slawson atop an unnamed hill in the Town of Sanford. It is approximately 2,087 feet (636 m)[8] above sea level.[9] An area due east on the Delaware County line inOquaga Creek State Park also lies within the same elevationcontour line. The lowest point is 864 feet (263 m) above sea level, along the Susquehanna River, at the Pennsylvania state line.
The county has a total area of 716 square miles (1,850 km2), of which 706 square miles (1,830 km2) is land and 9.7 square miles (25 km2) (1.4%) is water.[10]
