Timeline of town creation in the Hudson Valley: The towns and cities of the Hudson Valley were created by the U.S. state of New York as municipalities, in order to perform the services of local government.  In 1683, prior to the creation of modern towns, the Province of New York was divided into twelve counties for administrative purposes by the Colonial Governor of New York.  In the Hudson Valley, these divisions included Dutchess, Orange, and Ulster counties.  Dutchess and Orange remained unorganized until 1713, with Dutchess administered from Ulster; Orange would be administered from New York County.  Future counties would be formed and towns exchanged over time, with Rockland County split from Orange in 1799, at which time the southern towns of Ulster were transferred to Orange as compensation for the loss; and Putnam County from Dutchess in 1812, these county's towns can trace their origins to towns and precincts that were formed in their parent counties.  Another change that occurred was the transfer of Dutchess County's northern section, the Livingston Manor, to Columbia County.  Greene County was formed in 1800 by the combination of the southernmost towns of Albany County with the northernmost towns of Ulster.  The history of the towns of Greene and Columbia counties can be found at the Timeline of town creation in New York's Capital District.
