Albany County was one of the original twelve counties created by the [[Province of New York]] on November 1, 1683.<ref>(N.Y. Col. Laws, ch 4/1:122)</ref> At the time, it included all of New York state north of [[Dutchess County, New York|Dutchess]] and [[Ulster County, New York|Ulster]] counties, all of what is now [[Bennington County, Vermont|Bennington County]] in [[Vermont]].<ref name="NYATLAS">Thorne, Kathryn Ford, Compiler & Long, John H., Editor: ''New York Atlas of Historical County Boundaries''; The Newberry Library; 1993.</ref>

On May 27, 1717, Albany County was adjusted to gain an indefinite amount of land from Dutchess County and other non-county lands.<ref>(N.Y. Col. Laws, ch 333/1:915).</ref>

On October 7, 1763, [[George III of the United Kingdom|King George III]], as part of his [[Proclamation of 1763]], created the new [[Province of Quebec (1763–91)|province of Quebec]], implicitly setting the northern limit of New York at the parallel of [[45th parallel north|45 degrees north latitude]] from the Atlantic-St. Lawrence watershed westward to the [[St. Lawrence River]], implicitly setting the northern limit of Albany County, but it was never mapped.<ref>(Cappon, Petchenik, and Long, 1, 77, 90; Shortt and Doughty, 119—120).</ref>

On July 20, 1764, King George III established the boundary between [[New Hampshire]] and New York along the west bank of the [[Connecticut River]], north of [[Massachusetts]] and south of the parallel of [[45th parallel north|45 degrees north latitude]]. Albany County implicitly gained present-day [[Vermont]]. Although disputes occasionally broke out later, this line became the boundary between New Hampshire and Vermont, and has remained unchanged to the present. When New York refused to recognize land titles through the [[New Hampshire Grants]] (towns created earlier by New Hampshire in present Vermont), dissatisfied colonists organized in opposition, which led to the creation of [[Vermont Republic|independent Vermont]] in 1777.<ref>(Slade, 13—19; Van Zandt, 63).</ref>

On July 3, 1766, [[Cumberland County, New York|Cumberland County]] was partitioned from Albany County to cover all territory to the northern and eastern limits of the colony, including [[Windsor County, Vermont|Windsor County]], most of [[Windham County, Vermont|Windham County]], and parts of [[Bennington County, Vermont|Bennington]] and [[Rutland County, Vermont|Rutland]] counties in present-day [[Vermont]].<ref>(N.Y.

On June 26, 1781, Bennington County, Vermont, attempted to annex a portion of Albany County that today includes portions of [[Washington County, New York|Washington]] and [[Rensselaer County, New York|Rensselaer]] counties to form what they called "The West Union".<ref>(Vt. State papers, 13:45–46).</ref> The fledgling United States – under the [[Articles of Confederation]] – arbitrated this annexation, and condemned it, resulting in Vermont ceasing the annexation on 1782-02-23.<ref>(Vt.
