The history of Briarcliff Manor 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 in North America|Archaic period]], but significant growth in the settlements that are now incorporated into the village did not occur until the [[Industrial Revolution]].<ref name="Changing Landscape"/>{{rp|page=5}}

In the [[Pre-Columbian era|precolonial era]], the area of present-day Briarcliff Manor was inhabited by a band of the [[Wappinger]] tribes of Native Americans, known as ''Sint Sincks'' (or "Sing Sings"). They owned territory as far north as the [[Croton River]].<ref name="pamphlet"/><ref name="Ossining"/><ref name="Hudsonnatives"/> In the 1680s, [[Frederick Philipse]] purchased about {{convert|156000|acre|km2|0}} from the Sint Sincks, and named it [[Philipsburg Manor]].<ref name="1939history"/> The Philipses lost their claim to the land because of the [[American Revolutionary War]]; the family, which was [[Loyalist (American Revolution)|Loyalist]], had its property confiscated in 1779.<ref name="FamilyAlbum"/>{{rp|page=4}}<ref name="1952history"/>{{rp|pages=2–3}} The area remained largely unsettled by colonists until after the war; in 1693, fewer than twenty families lived in the {{convert|50000|acre|km2|adj=on|0}} area of Westchester which included Briarcliff Manor.<ref name="Changing Landscape"/>{{rp|page=11}}
