Although it’s not typically what you would think of when the word “gang” comes to mind, the Irish Republican Army operates in a manner similar to many of the gangs on this list, with violence being their forte. As a paramilitary group the IRA is responsible for numerous deaths and terrorist attacks and has as its goal the eradication of Northern Ireland and a unified Irish government.
Known for wearing the color red and their intense rivalry with the Crips, the Bloods were originally a set, or faction of the Crips. After breaking off they were outnumbered 3:1 which caused them to resort to extreme acts of violence for which they are still known today.
A relatively smaller gang with few allies the Texas Syndicate is not to be underestimated. One of the gangs it is allied with, however, is Los Zetas (#4) and the Syndicate has been known, along with MS13(#2) for carrying out many of the Zeta’s contract killings within the United States.
This massive Chinese crime syndicate is actually a conglomerate of gangs that has over 2.5 million members all over the world. While each branch has its own customs and practices, the triads as a whole are known for their very organized structure and intense, bloody rituals.
Similar to Hell’s Angels and operating under similar philosophies the Mongols was actually started as an alternative to their more popular counterpart for people of other races. Not surprisingly the Mongols and Hell’s Angels are rivals and have been known to engage in violent confrontations.
It has been said that on average everyday someone in Los Angeles County is assaulted by an 18th Street Gang member.

One of the most powerful drug cartels in the world, Los Zetas is responsible for so much death and destruction that it would be hard to fully describe its magnitude.

Widely known for their practice of not only killing their rivals, but also all of their family members, the Russian Mafia brings new meaning to the word “cold-blooded”.

One of the most violent gangs in the world, MS-13 makes most other gangs look like high schoolers dealing marijuana. It was started in California in the 1980’s when a group of Salvadorians fled the civil war in their country. Since then it has grown to over 70,000 members with operations throughout North and Central America. They have been known for acts of extreme and unprovoked violence which often include gruesome dismemberments, even against women and children.
Operating in the slums of Nairobi this extremely violent gang syndicate stands at about 100,000 members strong. In the past its members have been known for their signature dreadlocks and a practice of bathing in blood.

Unlike most gangs who identify themselves by either clothes or body markings, the Mungiki have opted for something a little more representative of their ideals – a severed human head on a stick.
