The American Mafia is a large criminal group. 



The American Mafia is a large and organized group of criminals. 

The group grew as people moved to the United States. Many immigrants came from Sicily and Southern Italy in the late 1800s. They often lived in poor neighborhoods in New York City. These areas included East Harlem, Brooklyn, and the Lower East Side. 
History shows how these groups became very powerful. In the late 1860s, newspapers reported gang wars in New Orleans. These gangs were named after the Sicilian cities they came from. One man named Giuseppe Esposito was an early member. He moved to New York and was later arrested in 1881. In New York, a man named Paul Kelly led the Five Points Gang. 
A major change happened during a time called Prohibition. In 1919, a new law made it illegal to sell alcohol. 
Today, the Mafia is still active in many different places. They are very busy in the Northeastern United States. You can find them in New York, Philadelphia, and New Jersey. They are also active in cities like Chicago and Detroit. 
The American Mafia is a highly organized criminal society based in North America. It is often called the Italian-American Mafia, the Mob, or Cosa Nostra. The term Cosa Nostra is used by its members, while the American government uses the term La Cosa Nostra (LCN). The name comes from the original Sicilian Mafia.
The organization is built upon a specific structure of units called "families." Despite the name, these are not groups related by blood. Instead, each family is a distinct criminal organization that operates within its own specific territory. To manage these different groups, a body known as the Commission provides nationwide coordination. The Commission consists of the bosses from the most powerful families. 
In New York City, the organization is divided into five main families. These are known as the Five Families: the Gambino, Lucchese, Genovese, Bonanno, and Colombo families. 

The history of the American Mafia began with waves of Italian immigration. During the late 19th and early 20th centuries, many people moved from Sicily and Southern Italy to the United States. They often settled in impoverished neighborhoods in New York, such as East Harlem, the Lower East Side, and Brooklyn. 
One of the earliest recorded instances involved Sicilian gangs in New Orleans in the late 1860s. These gangs were named after their home cities: Palermo, Trapani, and Messina. Another early figure was Giuseppe Esposito, the first known Mafia member to immigrate to the U.S. In New York, Paul Kelly founded the Five Points Gang in the 1890s. This gang was very powerful in the Little Italy section of the Lower East Side. Kelly recruited several men who became famous crime bosses, including Al Capone and Lucky Luciano. 
A major turning point for the Mafia was the era of Prohibition. In 1919, the 18th Amendment made it illegal to manufacture or sell alcohol. This created a massive demand for illegal liquor. Criminals found they could make huge fortunes by shipping alcohol from Canada, the Caribbean, or the Midwest. 
Today, the Mafia continues to operate alongside other organized crime groups. It maintains connections with Italian groups like the Sicilian Mafia, the Camorra, and the 'Ndrangheta. While many other crime groups have increased in number, the Mafia remains a dominant force in organized crime. It has a significant presence in the Midwest, including Chicago, Detroit, and Kansas City. It is also active in places like Florida, Las Vegas, and Los Angeles.
