CATEGORIES OF TERRORIST GROUPS
There are many different categories of terrorism and terrorist groups that are currently in use. These categories serve to differentiate terrorist organizations according to specific criteria, which are usually related to the field or specialty of whoever is selecting the categories. Also, some categories are simply labels appended arbitrarily or redundantly, often by the media. For example, every terrorist organization is by definition "radical", as terror tactics are not the norm for the mainstream of any group.
Separatist. Separatist groups are those with the goal of separation from existing entities through independence, political autonomy, or religious freedom or domination.
Revolutionary. Dedicated to the overthrow of an established order and replacing it with a new political or social structure.
Political. Political ideologies are concerned with the structure and organization of the forms of government and communities.
Religious. Religiously inspired terrorism is on the rise. While Islamic terrorists and organizations have been the most active, and the greatest recent threat to the United States, all of the major world religions have extremists that have taken up violence to further their perceived religious goals.
International or Transnational. International groups typically operate in multiple countries, but retain a geographic focus for their activities. Transnational groups operate internationally, but are not tied to a particular country, or even region.
