In the 1900's, radical political ideas and improvements in weapons gathered the small groups of "soon to be terrorists." Anarchists believed in "propaganda of the deed" produced some striking successes, assassinating heads of state from Russia, France, Spain, Italy, and the United States. However, their lack of organization and refusal to cooperate with other social movements in political efforts rendered anarchists ineffective as a political movement. In contrast, Communism's role as an ideological basis for political terrorism was just beginning, and would become much more significant in the 20th century.
There are two levels of organization, hierarchical and networked. The age of an organization is one of the determinations of whether it is likely to adopt a network or hierarchical structure. Newer groups tend towards organizing or adapting to the possibilities inherent in the network model. Ideology can have an effect on internal organization, with strict Leninist or Maoist groups tending towards centralized control and hierarchical structure. Within the larger structure, virtually all groups use variants of cellular organizations at the tactical level to enhance security and to task organize for operations.
Terrorist groups that are associated with a political activity or organization will often require a more hierarchical structure, in order to coordinate terrorist violence with political action. It also can be necessary for a politically affiliated group to observe "cease-fires" or avoid particular targets in support of political objectives. This can be difficult to enforce in networked organizations.
Money for the Terrorists
Ten years ago, the guesstimate for the value of money laundering was one trillion dollars
The first known terrorists were the Zealots and the Judeas. They were known as sicarii to the Romans or dagger-men. The group after the "dagger-men" were the assassins. Their leader was Hassam-I Sabbah, who held a cult in the mountains of Northern Iran. Together they were the forerunners of modern terrorists in aspects of motivation, organization, targeting, and goals. Secondly, although both were ultimate failures, the fact that they are remembered hundreds of years later, demonstrates the deep psychological impact they caused.
