Just a reminder that in Victoria missionaries must be treated in a totally different way from EU. In Africa missionary activity predated actual colonization by 30 to 50 years - and was very often the pretext for colonization. The activities of the Catholic White Brothers and the Church (or London) Missionary Society and Basel Missionary Society must be handled apart from the governments. Otherwise we'll have a "Swiss" empire in Tanganyika and Kenya - one of the places where the Basel mission was heavily involved.
Sponsoring missionary activity should of course increase the prestige of all nations involved, as should "humanitarian intervention" such as suppressing the slave trade.
