Portions of the township were taken on March 29, 1864, to form the town
Union Hill, which became part of
Union City in 1925.[1] A portion of Union Township was annexed by
Guttenberg in 1878.[1]
On July 5, 1898, the residents of the remaining portions of Union Township passed a referendum to incorporate the town of
West New York, which became effective as of July 8, 1898; With the creation of West New York, Union Township was dissolved.[1][2]
Two other municipalities in New Jersey are currently named Union Township. One is in
Hunterdon County and the other is in
Union County.
