The first Catholic Missionaries in what is now called Zambia were the international Society of the Missionaries of Africa, popularly called 'The White Fathers’ because of their white dress. They arrived from what is now called Tanzania in 1891, and established the first mission post called Mwambwe Mwela. They were hierarchically structured with Bishop Joseph Dupont firmly in charge , something that appealed to the Bemba overlords. One of the reasons that bloodshed was avoided was his reconciliation during one of their succession disputes. They settled down successfully in the North of what was then called Northern Rhodesia but did not follow those who migrated to the copper mines and the capital Lusaka during the 1930s. This practice was changed in 1965, after the Second Vatican Council, when a younger group of White Fathers responded to the national requirements of the apostolate.
