The Province of New York was an English colony that existed roughly within the current boundaries of the State of New York. The original boundaries also encompassed the current states of New Jersey and Vermont.
The province was granted to James, Duke of York, following the final acquisition of the New Netherlands colony from the Dutch in 1674, and was thereafter the possession of the holder of the title of the Duke of York. In principle, the form of government was absolutism, with the Duke of York holding supreme control. In practice, many decisions were carried out by provincial governor, appointed by the Duke of York, as well as a provincial legislature, which was elected among landholders.
Albany County: Contained all of the region that is now northern and western New York. Also contained the area that is now Vermont. In addition as there was no fixed western border to the colony (sea-to-sea grant), Albany County theoretically extended to the Pacific Ocean. Most of this land has now been ceded to other states and most of the land within New York has been divided into new counties.
