The Manor of Rensselaerswyck was created as a district within the county in 1772, and later divided into two districts, one on each side of the Hudson River in 1779. The west district included all of what is now Albany County other than lands were in the city of Albany at the time. Though the Manor of Rensselaerswyck was the only district (along with the city of Albany) in what is today Albany County, it was not the only district in what was Albany County at the time. Pittstown in 1761, and Duanesburgh in 1764, were created as townships. But when districts were created in 1772, those townships were incorporated into new districts, Pittstown in Schaghticoke and Duanesburgh into the United Districts of Duanesburgh and Schoharie. Schenectady was also made from a borough to a district in 1772. Other districts established in 1772 were Hoosick, Coxsackie, Cambridge, Saratoga, Halfmoon, Kinderhook, Kings, Claverack, Great Imboght, and the Manor of Livingston.
