The history of Briarcliff Manor, a village in Westchester County, New York, can be traced back to the founding of a settlement between the Hudson and Pocantico Rivers in the 19th century. The area now known as Briarcliff Manor had seen human occupation since at least the Archaic period, but significant growth in the settlements that are now incorporated into the village did not occur until the Industrial Revolution. The village, which was incorporated with one square mile in 1902, has expanded primarily through annexation: of Scarborough in 1906 and from the town of Mount Pleasant in 1927 to its current area of 6.7 square miles (17 km2). The village has also grown in population; from 331 when established to 7,867 in the 2010 census. (Full list...)
