Ilorin journal of sociology. 8(1): 149-167, Published by the Department of Sociology, Faculty of Social Sciences, University of Ilorin, Ilorin Nigeria.1117-9481https://uilspace.unilorin.edu.ng/handle/123456789/16332The role of youths in the development of a society cannot be over-emphasised. This is because youths in any polity forms the major part of the society meaning that the society is incomplete without the youths and as such they form the backbone of any nation in the sense that they can change the future of any nation for better with their courageous behaviour. This cannot however, be achieved with restive and violent youths. It is quite unfortunate that one of the characteristics of Nigeria's Fourth Republic is the increasing spate of youth violence and restiveness which has characterised its socio-political and economic processes. The paper discusses youth restiveness in Nigeria 's Fourth Republic pointing out the causal factors and the resultant effect of violence on Nigeria 's national security. The paper therefore argues that there is a strong relationship between violence and youth restiveness. Deriving largely from data gathered through secondary source, the paper adopted the frustration-aggression theory to explain the restive and violent nature of youths in Nigeria. Lastly, the paper suggests viable panaceas for reducing, if not totally. curbing restiveness and violence in the country.enyouths Restiveness. UnemploymentViolenceNational SecurityNiger-DeltaArticle
