Throughout much of its history, the community was split into two separate municipalities: a township and a borough. The central borough was completely surrounded by the township. The borough seceded from the township in 1894 in a dispute over school taxes; the two municipalities later formed the Princeton Public Schools, and some other public services were conducted together before they were reunited into a single Princeton in January 2013. Princeton Borough contained Nassau Street, the main commercial street, most of the university campus, and incorporated most of the urban area until the postwar suburbanization. The borough and township had roughly equal populations. Other major streets include Harrison, Witherspoon, Nassau, Bayard, Washington, and Stockton.
