What are the four biggest gangs in the world? Introduce their history in detail. Thank you!

Base: Chicago, new york.

Peak period: 1950s.

The American mafia is actually the egg laid by Italy's "our cause" on the other side of the Atlantic.

In the 1920s and 1930s, Italian dictator Mussolini severely suppressed "our cause", and "godfather" Don Vito also died in prison. In this environment, a large number of "our cause" members fled, and the preferred destination was new york, USA.

After nearly 20 years of development, the American mafia has gradually reached its peak. In new york, five mafia families (Bujano family, Kolobo family, gambino family, Genaux family and Luches family) control a large number of industries, and their influence has also penetrated into many trade unions, and they have taken this as a clue to expand to the whole country.

However, in the late 1970s and early 1980s, with the promulgation of the Law on Combating Corruption of Criminal Organizations and other similar laws, as well as the government's witness protection plan, it dealt a heavy blow to the five families. The American mafia is gradually declining.

At present, American mafia forces are limited to new york and Chicago. Years of government repression have left them a livelihood.

Main features: insufficient loyalty. Because the American government cracked down very severely, most mafia members chose the latter between imprisonment and betrayal. Regardless of the family reputation and tradition, the younger generation does whatever they want, which makes the internal contradictions of major families numerous.

Prospect forecast: At present, although the influence of American mafia is not as good as before, it still controls many gambling, drug trafficking and usury businesses. Some experts believe that if the government relaxes its crackdown on the mafia, it may revive it.

The Russian Mafia

Base: Moscow Far East

Peak period: late 1990s.

199 1 year, the Soviet union collapsed. Due to the political and economic chaos in successor Russia, the following year 10 became the golden age for the rapid growth of Russian mafia.

Unlike the Italian mafia, quite a few members of the Russian mafia have received complete military training. For example, in Central Europe, during the Cold War, the Soviet Union deployed the most elite troops in East Germany. After the disintegration of the Soviet Union, 300,000 troops lost their direction almost overnight, and these people soon became targets of the mafia. It is estimated that about 400 paramilitary units are directly involved in the activities of the Russian mafia. There are also hidden organizations in the army, which cooperate with the mafia to engage in drug trafficking and weapons smuggling. After Putin became president, Russia's political situation has gradually stabilized and its economy has been effectively restored, but it still takes more time to rebuild social and legal order. During this period, the momentum of the crazy development of the Russian mafia has been contained, but it is still growing.

Main features: ruthless. As soon as the Russian mafia entered the world, it left people with the impression of fear with its large-scale kidnapping, assassination and explosion. For a few kilograms of drugs, tanks will also become their means of transportation, and rocket launchers and other weapons are often used. Journalists, police and even senior government officials will be targeted. In September 2006, kozlov, deputy governor of the Russian Central Bank, was shot dead for leading the anti-money laundering campaign.

Prospect forecast: With the government stepping up the crackdown, in recent years, the Russian mafia is gradually getting rid of the invulnerable traditional mode, "bleaching" business, starting to engage in port trade, banking and other businesses, and putting more energy into collusion between officials and businessmen and behind-the-scenes transactions. In addition, the Russian mafia is still trying to infiltrate abroad and has established contacts with criminal gangs in many countries.

Yamaguchi formation of Japan

Base: Tokyo Osaka

Peak period: early 1990s.

The history of Japanese gangs can be traced back to17th century.

1604, Japanese general Tokugawa Ieyasu unified the whole country, ending centuries of civil war. Ordinary people can live a stable life, but thousands of warriors who once belonged to local governors are unemployed. These people are gradually marginalized and become ronin. They had nothing to do all day, so they began to attack the common people, and the common people also organized forces to resist the ronin.

Today's Japanese gangs say that these folk armed forces with samurai spirit are their ancestors.

Japan is the only country in the world that recognizes the legitimacy of gangs. There are nearly 3,000 gangs, large and small, and the Yamaguchi group is the largest, with nearly 40,000 members, accounting for 70% of the total number of Japanese gangs.

In addition to operating casinos and pornography, the most important "business" of the Yamaguchi group is to collect protection fees. They often threaten a scandal of a company or its responsible person to extort cash or a large number of loans that cannot be repaid. In the 1970s, when Japanese companies began to invest abroad on a large scale, the extortion activities of the Yamaguchi group reached a climax. Whether in London or Hawaiian beaches, Japanese companies have to pay protection fees as they do in Tokyo. Of course, these transactions are carried out behind the scenes, seemingly calm, and the host country is unaware of what happened, while the Japanese police usually regard the collection of protection fees as personal transactions and do not interfere.

Main features: open activities and tight organization. All members of the Yamaguchi group are well dressed, wearing famous brands and carrying business cards with them. Only tattoos on the back and hands without little fingers (members of the Yamaguchi group are required to cut off a little finger to show loyalty) will remind people of their true identity.

Prospect forecast: Since 199 1, Japan has promulgated a violent society countermeasure bill to restrict gang activities, and the fighting between gangs such as the Yamaguchi group has also broken the public's fantasy of the gangster "Robin Hood". According to the police, in the eyes of young people who are not deeply involved in the world, the image of the Yamaguchi group has been greatly reduced, and it is even difficult to recruit. In June 5438+10 last year, Hongdao, the largest faction of the Yamaguchi group, was targeted by the police. At present, 33 leaders of Hongdao Association have been arrested. Japanese police officials said that they would launch an all-out war with Hongdao News Agency.

Mexican mob

Base: US-Mexico border

Peak period: 2006

Mexican mafia, belonging to Italian mafia, consists of six families: Culiacan, Guadalajara, Juarez, matamoros, Sonora and Tijuana.

In Latin America, the Colombian mafia was once rampant, but it gradually declined under the joint attack of the United States and the Colombian government and was replaced by Mexican gangs. Today, six families control the 3,200-kilometer-long US-Mexico border, engaging in drug trafficking, illegal immigration and arms smuggling.

In addition, kidnapping and extortion are also the "main business" of Mexican gangs, and the number of kidnappings here is second only to Colombia, ranking second in the world. Kallet, the most wanted man arrested in 2000, has committed more than 20 major crimes by himself. No one can escape from the owner of Chrysler Automobile Company to the president of Presidential Hotel Group as long as he is eyeing him. Sometimes, foreign ambassadors are not immune. In June 2002, King Carlos of Spain visited Mexico. On the way of the Spanish ambassador to Mexico to meet the king at the airport, the gang robbed the car with the Spanish flag and diplomatic license plate. Afterwards, the embassy said that they didn't intend to report the case to the police because "it's a waste of time and it won't work."

Because of the powerful gangs, it has seriously affected Mexico's tourism, economic development and even its international image. Mexican society generally believes that the corruption and inaction of the police department are the main reasons for the deterioration of social security.

Main features: Make full use of the network. Mexican gangs are not just barbarians who can only fight and kill. They know how to use the most advanced means to achieve their goals. Not long ago, a video of killing a rival gang member was posted on youtube. Before that, gangs used video clips to recruit members online.

Prospect forecast: At the end of 2006, Felipe Calderon was sent to the presidential palace by voters who held high the campaign promise of "completely improving social security". In solving the increasingly serious problem of "cracking down on evil", the biggest feature of Calderon's government is the use of troops. Over the years, Mexico has regarded "cracking down on evil" as a military action, sending troops to cities where violent crimes are rampant and setting up special commandos to "crack down on evil". By the beginning of 20 10, there were as many as 50,000 soldiers in Mexico who participated in "cracking down on evil".

For Mexico, if the "strike hard" campaign can't be persistently continued, the continued revenge of the gang forces may put the whole country in danger.
