The name Briarcliff has also been applied to other municipalities, including the 470-person town of Briarcliffe Acres in South Carolina; in naming it, the town's founder had drawn inspiration from Briarcliff Manor's name.
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 high school opened in 1928, and in 1946, the People's Caucus party, an organization which calls out interested residents for candidacy, was created.
Briarcliff Manor celebrated its semicentennial celebration from October 10–12, 1952, publishing a book about the village and its history; that year, the Crossroads neighborhood of 84 houses was completed.
It still remains primarily residential and its population is still considered affluent by U. The village has seven Christian churches for various denominations and two synagogues.
The oldest church is Saint Mary's Episcopal Church, built in 1851.
Law developed the village, establishing schools, churches, parks, and the Briarcliff Lodge.
