Since the end of the Cold War, the phenomenon of forced displacement gained more global attention. Forced displacement involves the involuntary movement of people from their habitual place of residence to a location within their country of nationality; or across an internationally recognised border. This situation in most cases exposes the displaced people to some vulnerabilities. Among other classes of displaced people, the most notable groups of concern are refugees and internally displaced persons (IDPs). In contemporary time, conflict is identified to be the primary cause of forced displacement. Since 2009, the Boko Haram insurgency and the counter-insurgency by the Nigerian security forces turned northeast Nigeria into a conflict zone. The crisis has forced more than 2 million people to flee for safety within Nigeria as internally displaced persons (IDPs); while many crossed the border into countries neighbouring Nigeria from the Lake Chad region as refugees. This paper explored and discussed the suffering of the people internally displaced by Boko Haram conflict from the framework of forced displacement. It is found that, the IDPs in Nigeria suffered from multifaceted problems, ranging from the issues of inadequate life-saving assistance, protection related crisis, and the unclear prospect of achieving durable solutions. Moreover, the lack of a clear national policy, institutional, and legal frameworks in addressing internal displacement in Nigeria is found to be the prime cause of the intensification of the plight of IDPs. Thus, it is recommended that, there should be a legally backed national policy on IDPs, which should include punitive measures for corrupt humanitarian officers. Also, provision should be made for effective coordination among national humanitarian agencies. Lastly, a clear rule of engagement between the Government and the international humanitarian agencies should be clearly defined.
