History
Linden was originally formed as a township on March 4, 1861, from portions of Elizabeth, Rahway and Union Township. Portions of the township were taken to form Cranford (March 14, 1871), Linden Borough (March 30, 1882) and Roselle (December 20, 1894). Linden was incorporated as a city by an act of the New Jersey Legislature on January 1, 1925, replacing both Linden Township and Linden Borough, based on the results of a referendum held on November 8, 1923. The city's name derives from linden trees brought from Germany.
