The crises rocking the foundations of this world and threatening its existence have assumed a horrifying dimension. This situation is compounded by the increasing drift by young people into radicalized violent extremist militant groups. This paper attempts a conceptual analysis of the term radicalisation, the processes involved in it, its components, as well as the rationale behind the influx of young ones into radicalized violent extremist groups. It also highlights the implications of radicalisation for education in Nigeria, and finally suggests ways to assist in deradicalising the youths.
