Since the formation of the Irish Province in 1860, Irish Jesuits have undertaken three main overseas missions (Australia, Hong Kong and Zambia). More than 120 Irish Jesuits have worked in Zambia. The Vice-Province of Zambia was formed in 1969 and the Province of Zambia and Malawi was established in 1992. The Irish Jesuits' work in Zambia is complemented by other Jesuit Provinces such as: Canada; Croatia; Oregon; Poland and Slovenia. The papers of the Zambian Mission chronicle the life and work of Irish Jesuits since their arrival, in what was then Northern Rhodesia, in 1946. The files of correspondence between Irish Jesuits working in Zambia and their Irish Provincials in Dublin illustrate the areas of work that they laboured in: parish work, education and development. Geographically, this took place in the southern part of the country and in the capital, Lusaka. The impact of the Irish presence is seen especially in Canisius High School and Charles Lwanga College of Education in Chikuni, the parishes in the Monze Diocese, and development projects around the diocese.
