New Jersey in the twentieth century underwent many changes. New Jersey's position along the Atlantic Ocean made it a prominent part of both of the World Wars. Despite rising in the Roaring Twenties, New Jersey's economy slowed with the start of the Great Depression. It also became a site for Nike missile batteries during the Cold War. In the 1960s, several race riots occurred following the start of urban decay. Through the 1970s, urbanization increased again, and these problems slowed.
