Abstract
As for the origins of Kharijites, many of Islamists have laid strss on their fanaticism and a narchy, and have attrbuted, in relaton to the effects of tue First Civil War, their origins, to the relization of the nomadic Arabs' inclination for the anarchy. Aocording to their opinions, the First Civil War was causeb by the clash of interests among vorious faction, but it's basic impulse was the reclamation of nomadic tribalism, and the outbreak of Kharijites movement should be considered as an expression of anarchistic tribalism. My opinion is that the origions of Kharijisnom was a form of Islamization of nomadic Arabs (“The First Civil Wat and the Kharijites”, World of Islam, VI, Tokyo, 1968, pp. 11-34). Many treatises on the Kharijites discussed the problem from the viewpoint of Itlamic Government. But in the present monograph I like to amplify my opinion in the former article on the tignificance of the First Civil War and the origins of Kharijites as examined from the nomadic Arabs' viewpoint, so as to find that the basic impulse of the First Civil War was not the tribalism, but the economic motives, and that the origins of Kharijism was based on the Islamization of nomadic Arabs.
