The Armed Forces Remembrance Day (AFRD), also simply known as Remembrance Day, is a public holiday in Nigeria celebrated observed on 15 January to commemorate the servicemen of the Nigerian Armed Forces. It also honors veterans of the World War I and II as well as the Nigerian Civil War. Being a former British colony, Remembrance Day was formerly celebrated on 11 November as Poppy Day in honor of the end of the First World War. Upon the government victory, against Biafran troops on 15 January 1970, the holiday was moved off the calendar of the Commonwealth of Nations and was changed to 15 January in commemoration of the conclusion of the Nigerian Civil War that sought to tear apart the unity of Nigeria.
