The Newark arc of 1967 in Newark, New Jersey was a very radical and horrible time, the worst in American history. The riots occurred between African Americans and Caucasians, police and the National Guard. The riot was not unexpected. Tension between cities dramatically increased in the 1960s due to under-employment of black people, inappropriate housing, police brutality and the elimination of black politics by the government. In 1967, Newark police had 1,500 members, of which only 10% were blacks.
The most notable urban riot was the New Arc riot in 1967 and the Stonewall riot in 1969, which were caused by various reasons. Overall, between 1964 and 1971, about 752 voluntary riots occurred in the black community of 316 cities in the United States in particular. However, the media has exaggerated many of these conflicts, and only the major disputes that have been discussed are serious about violence, arson and physical damage. Many social scientists thought of various theories when exploring various causes of this urban riot. These reasons include race discrimination and competition in ethnic labor in the community. In addition, scholars often focus on a wide range of trends to find out why cities can experience varying degrees of racial turmoil.
