The struggle for cultural supremacy is not only a fact of history but also an observable phenomenon of social existence. Perhaps, the frenzied defence of cultural identity is second only to the expression of territorial nationalism. Contemporary cultures of which Islam is a resilient part are engaged in a ceaseless war of survival. Following the 9/11 attack on the World Trade Centre in New York, Islam has come under intense scrutiny. What has followed is a feverish commitment to the obliteration of Islamic values at home and abroad and the intensification of the scheme to enthrone western culture. This raises many legal, constitutional and sociological questions as well as questions relating to the place of Islamic culture both on the international arena and within the Nigerian jurisdiction. The paper is dedicated both to defining the place of Islamic culture vis-a-vis freedom of conscience and the constitutional safeguards in place against the prejudices that confront Islamic civilisation.
