All Nations is the result of the merger in 1971 of three colleges, all of which prepared people to work in cross-cultural missionary service overseas: Mt Hermon Missionary Training College (founded 1911), Ridgelands Bible College (1919), and All Nations Bible College (1923). The last had changed its name to All Nations Missionary College in 1962, just prior to moving from Taplow, in Buckinghamshire, to Easneye Mansion near Ware in 1964. The first two exclusively trained women, while All Nations Missionary College trained both single men and married couples.
