History
Fairfield was originally settled as part of the broader Caldwell Township area before being incorporated as its own township in 1798, reflecting the gradual population growth and civic organization of northern New Jersey during the late 18th century. Throughout the 19th and early 20th centuries, the area transitioned from a largely agricultural landscape into a more developed community as railroads and roadways expanded access across Essex County. By the mid-20th century, post-war suburban growth transformed Fairfield into the residential and commercial township it is recognized as today.
