A timely publication when the need for greater understanding between Islamic and Western cultures is sharper than ever, the papers in this book are the result of an international conference entitled 'the Shari'ah debate and the shaping of Muslim and Christian identities in Northern Nigeria'. The conference was convened by the University of Jos in northern Nigeria in the wake of the religious/civil strife in the area in 2001 and 2002. The conference, which brought together scholars from Nigeria and overseas considered recent developments in law and religion, and shari'ah from local and global perspectives. The publication is intended to serve as an example of constructive dialogue in an academic setting between Muslims, Christians and those of neither religion, and as a permanent contribution to the literature on law and religion in Nigeria.

An unprecedented overview of anthropological and political science research on vigilantism in Africa which makes an important and innovative contribution to current discussions on the relationship between violent self-justice andstate and non-state agencies. Self-justice and legal self-help groups have been gaining importance throughout Africa. The question of who is entitled to formulate 'legal principles', enact 'justice', police 'morality' and sanction 'wrongdoings' has increasingly become a subject of controversy and conflict. These conflicts focus on the strained relationship between state sovereignty and citizens' self-determination. More particularly, they concern the conditions, modes and means of thelegitimate execution of power, and in this volume are seen as a diagnostics as to how social actors in Africa debate and practise socio-political order. State agencies try to bring vigilante groups under control by channelling their activities, repressing them, or using them for their own interests. Vigilante groups usually must struggle for recognition and acceptance in local socio-political spheres. As several of the contributions in the volume show, legal self-help groups in Africa therefore 'domesticate' themselves by, among other things, seeking legitimation, engaging in publicly acceptable non-vigilante activities, or institutionalizing what often began as a rather unrestrained and 'disorderly' social movement.

When democracy was introduced to Nigeria in 1999, one-third of its federal states declared that they would be governed by sharia, or Islamic law. This work argues that such a break with secular constitutional traditions in a multireligious country can have disastrous consequences
