The Alliance System of the Abu Sayyaf, 1993-2000

Unsettled conditions on Jolo and Basilan islands in the southwestern Philippines have seriously hampered efforts to obtain information about the Abu Sayyaf. The result has been a continuing ignorance over the most fundamental features of the group. In the attempt to broaden our understanding of its structure, this article examines data drawn from an array of sources in light of the authoritative work of Thomas Kiefer on the traditional Tausug alliance system on Jolo. It argues that the Abu Sayyaf consists of a system of alliance groups of the kind customarily found in Muslim Filipino societies.
