Camden was founded in 1828 by American immigrants, primarily Hispanic and Black citizens. The city's barrios were poor after the Great Depression of the 1930s, and it never recovered. Crime rates went up as poverty struck in, as the poor people murdered for money. Some of the destitute people joined gangs there. Camden's influence spread to nearby Philadelphia, where the Greco crime family and the Bruno crime family became dangerous and murder rates went up in Philadelphia. Camden remains a hotspot for organized crime and for gang violence, becoming the second-most dangerous city in the United States in the year 2010, being brushed aside by St. Louis in Missouri.
