Philipsburg Manor (sometimes referred to as Philipse Manor) was a manor located north of New York City in Westchester County in the Province of New York. Netherlands-born Frederick Philipse I and two partners made the initial purchase of land that had been part of a Dutch patroonship owned by Adriaen van der Donck. Philipse subsequently bought his partners out and added more land before being granted a royal charter in 1693 for the 52,000 acres (21,000 ha) estate, becoming its first lord.
After his death, the manor was split between his son and grandson, both of whom continued its development. Among the family's numerous enterprises, the Philipses engaged in the slave trade, using their own slaves to construct most of the buildings on the Philipsburg property. The tenant farmers on the manor represented a diverse population of Europeans.
The manor's property was confiscated during the American Revolution when Loyalist Frederick Philipse III, its third and final lord, was attainted for treason by New York's revolutionary government in 1779. The estate's land was used as collateral to raise money to fund the rebellion and later sold at auction. Some of the original structures still stand, including the Philipsburg Manor House in Sleepy Hollow, Philipse Manor Hall (the family seat) in Yonkers, and the Old Dutch Church of Sleepy Hollow, all of which are National Historic Landmarks.
