Islamist militant group, Al-Qaeda, founded by Osama Bin Laden operates as a network of multi-national stateless armies and is responsible for instigating violence among fanatical Muslims. Since its inception, the group has been held responsible for a number of civilian and military attacks in different countries.

From scratch, Bin Laden has worked to build Al-Qaeda as a conspiratorial network whose characteristic techniques include simultaneous bombing in different locations and suicide attacks. Most of the financing for the group came from the personal accumulations of Bin Laden which was estimated to be around $300 million. However, other forms of support came from heroin trade and donations from supporters across the world.

One of the most notable attacks by the organization is the September 11 attacks on New York City and Washington D.C. in which around 3000 victims and firefighters lost their lives. As retaliation, the US launched an international military campaign called the Global War on Terror.
