This paper considers the educational policy of the Church Missionary Society in Egypt in the above-mentioned period in an attempt to understand the mission's social impact in the light of, and in spite of, its lack of converts. It examines the Mission's goals for evangelizing among Muslim girls and the influence of the CMS on the development of girls' education, on religious and social identities. The main questions of the study may be stated as follows: (i) How and under what conditions do the CMS lady missionaries work on education in Cairo in the above-mentioned period? (ii) What was the educational policy of the Girls' Boarding School and to what extent did the missionaries reach their aims? (iii) How far and in what ways did this school affect the Christianising of Egyptian girls? (iv) What was the value of this school as a Mission training centre in a Muslim land? Furthermore, the purpose of this study is to determine on the one hand the substance of educational aims for Muslim girls from the standpoint of Christian values, and on the other hand to demonstrate that the Egyptian girls could have eventually been adaptable to the sceptical and materialistic European way of life.
