Generic Ethnic Crime Gang

""The only native American criminal class is politicians.""

- Mark Twain

In fiction, gangs tend to share a few common traits:
 * Family oriented, and headed by a patriarch.
 * Talk of honor and loyalty (except when dealing with enemies, of course).
 * An organised crime outfit.
 * Majority is one ethnicity, we get some of the language and customs for color - they may be referred to as "The [Ethnicity/Nationality] Mafia". Contrast with Equal Opportunity Evil.

The second and fourth points are commonly played for drama, as combined they easily spark conflict. A common convention is to have gangs of different ethnicities compete with each other, such as The Irish Mob vs. The Mafia.

See Ruthless Foreign Gangsters. In terms of Alike and Antithetical Adversaries, these guys fall on the "homogenous" side of the scale.

The most common types of gangs are:
 * The Cartel - South/Central American
 * The Irish Mob
 * London Gangster
 * The Mafia - Italian or Italian-American
 * The Mafiya - Russian
 * The Triads and the Tongs - Chinese
 * Yakuza - Japanese
 * The Yardies - West Indian

Other ethnic gangs are:

Black Gangsters
The classier, more organized version of Gang-Bangers (who frequently despair at the latter and wish they'd Stop Being Stereotypical). Compare with The Yardies, who are British/West Indian.

Film

 * American Gangster: Real life drug lord Frank Lucas models his empire on the Italians' to create an African-American mafia, with him as the patriarch.
 * He is also probably aware that no one would take his gang seriously enough to investigate. He's wrong, though.
 * Gambol from The Dark Knight
 * Lottery operators such as those depicted in the film Hoodlum
 * Mr. Black (haha, get it?) from Darkman appears to be one of these, from the way he dresses, but it's hard to tell because he is almost immediately killed by Durant.
 * The Boss's gang in Lucky Number Slevin.
 * Nino Brown in New Jack City.
 * One of the Feuding Families from Romeo Must Die was this type of mob, the other being a Triad.

Film

 * Marrying the Mafia features a Korean mob family.
 * The Hmong Gang-Bangers from Gran Torino.
 * The protagonist in the 1991 film The Perfect Weapon fights a Korean mob.

Live-Action TV

 * Various versions of this appear in Magnum, P.I.; there are Chinese ones, Japanese ones, and Southeast Asian ones. Not inappropriate as Hawaii has long had a large Asian population and Honolulu is a port for illegal as well as legal goods and services.

Video Games

 * Grand Theft Auto has the Da Nang Boys (Vietnamese gangsters), and Korean mobs, in addition to the Triad.
 * Kiryu Kazuma fights Korean gangsters in Yakuza 2.

Eastern European Gangsters
These gangs take advantage of the instability in the Balkans and flourished after the fall of communism. Stereotypically linked to people-smuggling, heroin, and forced prostitution.

Comic Books

 * In The Punisher comic "The Slavers", the eponymous white slavers are these.

Video Games

 * Grand Theft Auto IV features the (very significant in Real Life) Serbian and Albanian Mafias.

Greek Gangsters
Greek Gangs seem to be the go-to Ethnic Crime Gang for antiquities smuggling and gun-running; illegal (non-casino) gambling is another favorite.

Film
"Cousin Nick: (in a very cheerful tone) Hey Ian, we're gonna kill ya! Opa!"
 * Nick "the Greek" in Lock, Stock and Two Smoking Barrels

 * The Philadelphia Greek Mob, mostly active in the 1970s and 1980s.

Jewish Gangsters
These guys are usually involved with the Italian Mafia and based on Bugsy Siegel or Meyer Lansky. More modern ones will typically be Israelis—sometimes presented as Ruthless Foreign Gangsters—and always portrayed as some form of terrifying badass and involved in some way with the Mossad. Historically, the Jewish Mob was a dominant force in the brief period between when White America started seeing Irishmen as "white" and the rise of the more numerous Italian Mob. During that period, they were involved in the regularization and "professionalization" of organized crime in the US, with the establishment of The Commission (the Italian-American Mafia's coordination/dispute-resolution body) and Murder, Inc. (organized, professional hitmen) being the brainchildren of Jewish mobsters (the Commission and Murder, Inc.'s parent organization, the National Crime Syndicate were specifically Lansky's ideas).

Comic Books

 * The first arc of DC Comics book Caper by Judd Winick was about two brothers in the Jewish Mafia in turn-of-the-century San Francisco.

Film

 * Bugsy Siegel himself was played by Warren Beatty in the semi-biographical film Bugsy.
 * Meyer Lansky, Bugsy Siegel and Arnold Rothstein appear in Boardwalk Empire, along with other, fictional Jewish Gangsters such as Manny Horvitz. The show largely averts this trope, though, as the generals consider personal loyalty more important than ethnicity.
 * Moe Greene from The Godfather is based on Siegel.
 * Meyer Lansky expies:
 * Hyman Roth of The Godfather Part II
 * Robert De Niro's character "Noodles" from Once Upon a Time in America
 * Sam "Ace" Rothstien (also played by Robert De Niro) of Casino
 * The Rabbi and co in Lucky Number Slevin. Complete with ex-Mossad bodyguards.
 * Frankie "Four Fingers" and Uncle Avi's gang in Snatch, although neither actor playing them is actually Jewish (they're played by Puerto Rican Benicio del Toro and Italian-American Dennis Farina, respectively).
 * Nino in Drive is a Jewish gangster who sets the events of the film in action with his plan to rip off the East Coast Mob, his associate Bernie is played by a Jewish actor and is heavily implied to be Jewish as well.

Literature

 * Wolfshiem of The Great Gatsby is a Meyer Lansky expy.

Live-Action TV

Video Games

 * Isaac's gang in Grand Theft Auto IV.
 * The Cohen Crime Syndicate in L.A. Noire.

Western Animation

 * Zalmie Belinksy in American Pop.

Latin American Gangsters
Some can overlap with The Cartel, but The Cartel tends to be strictly based on drugs and has a physical base in South America.

Film

 * In the 1983 version of Scarface, Tony Montana's gang is Cuban.
 * Carlito's Way: Carlito is Puerto Rican.
 * The first wish results in Brendan Fraser's character becoming a Colombian drug lord in the Bedazzled remake, thanks to the Literal Genie Devil.

Video Games

 * Ricardo Diaz in Grand Theft Auto Vice City and Grand Theft Auto Vice City Stories. Then Tommy (an Italian-American) takes over his drug business.

Live-Action TV

 * The Indigenous Australian (Torres Strait Islanders) crime syndicate in The Straits smuggles drugs in one of the most naturally beautiful parts of the world (North Australia and Papua New Guinea). They also deal with Asian and Papua New Guinean criminal franchises. In this case, one of the co-founders of the indigenous crime gang is of Maltese ethnicity, however.

Video Games

 * The Tsoo from City of Heroes are ethnically Hmong -- a Southeast Asian people who live mainly in Southern China, Vietnam and Laos.

Film

 * Star Wars gives us the Hutts.

Live-Action TV

 * The Tauron Ha'la'tha from Caprica fits all four points (family-oriented with an old patriarch—the Guatrau—honor and loyalty, very organized, and all Taurons), despite including some elements of The Cartel (tattoos and rap, plus Taurons are Space Mexicans).
 * The stoicism, use of tattoos to indicate rank and status, strong family ties, and preference toward edged/bladed weapons looks a lot like the Japanese yakuza. The ha'la'tha look like an amalgamation of every stereotype about organized crime ever invoked in the media.
 * The Ha'la'tha's transition from freedom-fighting organization to organized crime is reminiscent of the Irish mob's roots in "defense societies" in the old country.
 * The Orion Syndicate in Star Trek. While they have many operatives of various races, the whole thing is run by the Orions.

Video Games
"Garrus: "Don't be fooled. Illium is just like Omega, only with more expensive shoes.""
 * In Mass Effect, Ethnic Crime Gang seems to be the hat of the Vorcha. Pretty much all you ever get to meet seem to belong to street gangs.
 * Though they usually have multi-species organizations, the Blue Skinned Space Babe race of the Asari seems to run almost all major crime in the galaxy. The asari planet Illium is officially a "special economic zone", but in reality that means it's a primary hub for everything that is illegal to sell elsewhere.

Literature

 * The Breccia in Discworld are the Troll Mob. The name is something of a Genius Bonus, as breccia is a kind of rock made from fragments of smaller rocks cemented together.
 * Erewhon in Honor Harrington is run by the descendants of gangsters. More specifically they used a planet as a money laundering center and it evolved into a fairly ordinary nation. Traces of its origin still remain but the old gangsters are more like a fairly informal but more or less civilized aristocracy; about as civilized as any other at least. One trace remaining is that in interstellar Realpolitik they are more likely to use traditional gangster methods (such as bribery, subversion, and manipulation) to outright Gunboat Diplomacy.
 * It is implied in Crown of Slaves that the theoretical potential of blood feud is still a thing among the most distinguished families of Erewhon, but that in practice the main effect is not to take politics to far lest one's own be the underdog in the future. The result is that internal politics is a stylized contest of shifting factions who always maintain certain limitations
 * The Scrags are descendant from a Slavic-Supremist warrior cult of eugenic "superbeings". They always have as leader the fiercest and strongest among them. Effectively they are human space orcs.
 * In the Vorkosigan Saga, "Jackson's Hole" is a planet inhabited by gangsters. These vary from the "not nice but not exactly evil" variety (like Ivan Vorpatril's in-laws) to the positively perverted (like people who raise slaves to remove their brains to sell their bodies to rich offworlders who want immortality, and one who collects torture victims as a "hobby").

Tabletop Games

 * In Traveller, the planet Granicus is run by gangsters. There are three main syndicates, two of which consider it just business and have no particular ethnic associations. The third, however, is a Solomani-supremist cult.
 * The Assassin's and the Thief's guilds in Tredroy in Banestorm. They control the crime in town within their respective categories. They are given an ambiguous recognition by the town authorities: after a thief is captured and flogged(or whatever) he is dumped in the Thief's Guild's turf at night. If he was a dues-paying member they will bring him back to his own associates. If not they will deal with matters appropriately.
 * At one time long gone by when the town of Tredroy was under siege the Assassins made an alliance with the government and well, began assassinating people.
