The newly established, post-Revolutionary War state of New Jersey went through several stages setting out how its local governments would be structured. Townships were drawn that included villages and open land. Once boroughs became available in New Jersey as a form of local government after 1878, between 1889 and 1899 Chatham Township lost all but one of the villages drawn into it, including Chatham (settled in 1710), which had been drawn into the new township in 1806. They seceded as soon as the bourough form of government became available.
Only Green Village, another early town that, like Chatham, dates to colonial times, was left under jurisdiction of "Chatham Township".
