The Mafia (also known as Cosa Nostra or The Commission) is a real-life criminal secret society which first developed in the mid-19th century in Italy. An offshoot emerged on the East Coast of the United States during the late 19th century following waves of immigration. In America, the Mafia often refers to Italian American organized crime in general, rather than just Sicilian American organized crime. Each Mafia family is lead by a Don or Capo Crimine.
The Mafia had dominated organized crime in the United States until the latter decades of the 20th Century, when non-Italian criminal organizations and street gangs rose in prominence. Over the years, the mafia families has come into conflict with each other and with other gangs.
- In GTA San Andreas, every gang but the Mafia have three gang member models. The Mafia have one extra, making four.
- There is a glitch in GTA San Andreas, there is a way to gain more gang territory throughout the state of San Andreas. To exploit the glitch, fly a plane into the southwest or southeast corners of the map, and continue onwards in the respective direction; continue this for a long period (30 real-world minutes is suggested), then either fly back (which will take a long time), or drown oneself after the 30-minute mark. After returning or awaking at a hospital, a glitch will have occurred, and there will be gang territories visible all over San Andreas. The Italian Mafia can now be encountered in Las Venturas, usually wielding Pistols and Desert Eagles, and driving Feltzers, Sentinels, or Admirals.
