The Order of the Knights of St. Mulumba (KSM) was established in Nigeria on June 14, 1953, by the Late Reverend Father Abraham Anselm Isidahome Ojefua, a Catholic priest and monk from Illah Monastery in present-day Delta State, and was modelled after the Sacred Order of Catholic Knighthood.
Founded to promote Catholic faith, spiritual growth, charity, unity, and service to humanity, the Order has grown into one of the largest Catholic lay organizations in Africa, with a membership of over 20,000 men and women dedicated to serving both the Church and society.
The women's wing, known as the Ladies of St. Mulumba (LSM), was inaugurated on June 24, 1978, in Calabar (present-day Cross River State), providing Catholic women with an active platform to participate in the mission and apostolate of the Order alongside their husbands and families.
Since its inception, the Order has expanded beyond Nigeria by establishing the Knights of St. Matia Mulumba in Kampala, Uganda, in 2004, and the Knights of St. Mulumba in Mamfe, Cameroon, in 2008, reflecting its growing regional influence and commitment to spreading the ideals of Catholic knighthood across Africa.
