In the 1960s, race riots erupted in many of the industrial cities of North Jersey. The first race riots in New Jersey occurred in Jersey City on August 2, 1964. Several others ensued in 1967, in Newark and Plainfield. Other riots followed the assassination of Martin Luther King Jr. in April 1968, just as in the rest of the country. A riot occurred in Camden in 1971. As a result of an order from the New Jersey Supreme Court to fund schools equitably, the New Jersey legislature passed an income tax bill in 1976. Prior to this bill, the state had no income tax.
