The present paper seeks to investigate the most influential social factors of crime in Ibn Khaldun's view through looking at the most important theories of criminology. On the one hand, Ibn Khaldun believes in man's will and admits the effect of environmental and social factors on man's acts by accepting his sociability, on the other hand. Therefore, he pays attention to different factors like luxury- orientation and interest conflict, rulers' oppression, weakness of social cohesion, and civil and foreign wars and considers these factors as the cause of many crimes including economic corruptions, murder, sexual offences, and social riots. Inb Khaldun's approach to analyzing the social factors of crime is more close to integrative and combinative theories. However, he considers luxury-orientation and conflict among city dwellers as the cause of many crimes, and, among all social factors, pays special attention to state and its political-economic corruptions.
