GreaterHarlem, in the northern section of theNew York Cityborough ofManhattan, has historically had highpoverty andcrime rates.[1]Crime in Harlem is primarily related to illicit activities such astheft,robbery,drug trafficking andprostitution. Criminal organizations such as streetgangs are responsible for a significant portion of crime, particularlyviolent crime. The leading cause of death among young black males in Harlem ishomicide.[2] According to a survey published in 2013 byUnion Settlement Association, residents of East Harlem perceive crime as their biggest single concern.[3] Greater Harlem has one of the highest violent crime rates in New York City despite significant declines from historic highs.

Greater Harlem was seen as sophisticated in the later part of the nineteenth century. Over the years, however, organized crime by gangsters ofItalian, andIrish origin, such as colorful personalities asLucky Luciano, began to rise in Harlem. This gradually built its notorious reputation.[4]
Since the 1920s, greater Harlem has been known as a major African-American residential, cultural and business center. Black residents began to arrive en masse in 1905, with numbers fed by theGreat Migration.[5][6] In the 1920s and 1930s, Central and West Harlem were the focus of the "Harlem Renaissance", an outpouring of artistic work without precedent in the American black community and it even came to be known as "the capital of black America". However, with job losses in the time of theGreat Depression and thedeindustrialization of New York City afterWorld War II, rates of crime and poverty increased significantly.[6]
In Italian Harlem an organization titled "the Black hand" had emerged between 1901 and 1921 in Second Avenue which indulged in blackmail. There were unsuccessful attempts by the Italian residents of Harlem in the 1930s to improve their housing situation. They failed, resulting in their migration out of Harlem; highly unhealthy slums contributed to this.[7] The Italian community living in Harlem who were seen in the streets as much as in their houses even established a "boys club" (started in 1927) in their midst to divert attention and to wean away the boys from the influence of the gangs. The Italian part of the Harlem constituted immigrants of 64 regional societies in 1934 and many of them observed festivals in the church of mount Carmel. They were also segregated from the Spanish part of the Harlem.[7]
In 1931,Dutch Schultz, a mobster, exercised control over the wealth of Harlem residents with perpetration of violence and blackmail involving banks, restaurants, and clubs, taking advantage of his political and police contacts. After he was killed in 1935, the mantle of control fell on theGenovese Crime Family, who ruled the roost for the next 50 years.[8]
DuringWorld War II, newspapers likeThe New York Times sensationalized the crime situation and claimed that it was going up. However, the ground situation did not reflect this view, because in 1942, there was a reduction in crime rate.[9]

Like in Chicago, New York City during the mid 20th century saw a dramatic increase in organized criminal rackets and the gangsters of Harlem have been among the most notorious in American history. Gangsters such asFrank Lucas, hailed as the "baddest dude on the mean streets of Harlem", operated a gang that smuggledheroin into the states from Vietnam in US warplanes in the late 1960s and early 1970s.[10] Major riots broke out in Harlem in 1964, violently suppressed by the police.[11]

Cheapcrack cocaine in East Harlem, which became a major issue in the 1980s, as author Russell Leigh Sharman puts it was "largely responsible for the devaluation of human life in East Harlem: it radically affected the economy of violence in relation to the illegal drug trade."[12]
Since New York City's revival in the late 20th century, greater Harlem has been experiencing social and economicgentrification. However, Harlem still suffers from many social problems. Large portions of the population receive a form of income support from the government, with 34.9%, 43.3%, and 46.5% of the populations of West, Central, and East Harlem receiving aid.[13]
There are many gangs in Harlem, often based in housing projects, such as 4thBlocc/9Blocc (Carver Houses); 1040 (Jefferson Houses); ChicoGang (Wagner Houses); EastArmy (East River Houses); BroadDayShooters (Washington Houses); TrainedToGo (Douglass) Houses);WuskiGang (Johnson Houses); TaftGhanistan (Taft Houses); and Las Vegas (Lehman Houses). When one gang member is killed by another gang, revenge violence erupts, which can last for years.[14] TheEast Harlem Purple Gang of the 1970s, which operated in East Harlem and surroundings, was anItalian American group of hitmen and heroin dealers.[15]
There are six subcommittees dealing with the key issues in greater Harlem. These are "crime and police, health and hospitals, housing and recreation, education, discrimination in employment, and discrimination in relief."[16] Harlem is patrolled by five precincts of theNew York City Police Department.[17] Manhattanville and Hamilton Heights are covered by the 30th Precinct.[18] while East Harlem South is patrolled by the 25th Precinct.[19] Central Harlem North is covered by the 28th Precinct[20] while Central Harlem South is patrolled by the 32nd Precinct.[21] East Harlem North is covered by the 23rd Precinct[22] while East Harlem South is patrolled by the 25th Precinct.[19]
The Harlem Community Justice Center identifies problems and seeks solutions for a variety of crimes and disputes in East and Central Harlem. The multi-jurisdictional civil and family court offers programs in conflict resolution, financial support, at-risk youth, and re-entry for ex-offenders. Its goal is to work together with a community in order to facilitate neighborhood renewal.[23]
Y.U.N.G Harlem is a non-profit organization that advocates for the area's youth while also providing leadership resources. The organization's leaders were honored atBlack Entertainment Television's 3rd annual "Black Girls Rock" awards.[24]
Likethe Bronx, Harlem and its gangsters have a strong link tohip hop,rap, andR&B culture in the United States, and many successful rappers in the music industry came from gangs in Harlem.[25]Gangsta rap, which has its origins in the late 1980s, often has lyrics that are "misogynistic or that glamorize violence", glamorizing guns, drugs and vulnerable women in Harlem and New York City.[26][25] In 2022, drill music, a subgenre of rap music flourishing in New York City, was blamed by MayorEric Adams for glorifying and even contributing to increased violence in communities like Harlem.[27][28]
