History North Caldwell was part of the Horseneck Tract, which was an area that consisted of what are now the municipalities of Caldwell, West Caldwell, North Caldwell, Fairfield, Verona, Cedar Grove, Essex Fells, Roseland, and portions of Livingston and West Orange. In 1702, settlers purchased the from the Lenape Native Americans for goods equal to $325. The explanation for the name "Horse Neck" lies in the language of its first Dutch settlers and not (as has been inaccurately reported) because of its irregular shape. This purchase encompassed much of western Essex County, from the First Mountain to the Passaic River.Hilltop Reservation, Essex County Department of Parks, Recreation, and Cultural Affairs.

In 1982, the borough was one of four Essex County municipalities to pass a referendum to become a township, joining 11 municipalities that had already made the change. Ultimately, more than a dozen Essex County municipalities reclassified themselves as townships in order take advantage of federal revenue sharing policies that allocated townships a greater share of government aid to municipalities on a per capita basis."Chapter VI: Municipal Names and Municipal Classification", p. 73.

"In 1978, South Orange Village was the first municipality to change its name to the 'township' of South Orange Village effective beginning in entitlement period 10 (October 1978 to September 1979). The Borough of Fairfield in 1978 changed its designation by a majority vote of the electorate and became the 'Township of Fairfield' effective beginning entitlement period 11 (October 1979 to September 1980).... However, the Revenue Sharing Act was not changed and the actions taken by South Orange and Fairfield prompted the Town of Montclair and West Orange to change their designation by referendum in the November 4, 1980, election. The municipalities of Belleville, Verona, Bloomfield, Nutley, Essex Fells, Caldwell, and West Caldwell have since changed their classification from municipality to a township."Narvaez, Alfonso A.

"Under the Federal system, New Jersey's portion of the revenue sharing funds is disbursed among the 21 counties to create three 'money pools.'
