Westchester County is located in southern New York, also known as Downstate.
Dutch settlers began arriving in the 1620s, followed by settlers from England in the 1640s.
Westchester County was one of the original twelve counties of the Province of New York, created by an act of the New York General Assembly in 1683.
In 1788, five years after the end of the war, the county was divided into 20 towns.In 1874, the western portion of the present Bronx County was transferred to New York County, and in 1895 the remainder of the present Bronx County was also transferred to New York County.These would later split from Manhattan to form their own county.In 1798, the first federal census recorded a population of 24,000 for the county.Two developments in the first half of the 19th century – the construction of the first Croton Dam and Aqueduct, and the coming of the railroad – had enormous impacts on the growth of Westchester.
