The establishment of educational institutions and indeed, education and the instructor are the factors that assist humankind to have both knowledge and an open mind. In this context, Africa was viewed by the Europeans as an appropriate place for missionaries' educational work and an ideal area for the spread of Western education. Christian missions were very active in Colonial West Africa. It was through their establishment to educational institutions that people had access to Western education. Effectively, their work bore a great success in Sierra Leone, which had certain significance in the sense that it was the first land on which the British missionaries set foot. The establishment of schools and the spread of Western education were the factors that accelerated the rate of change in Sierra Leone, particularly in the Colony. Western education fell upon the receptive ears of Sierra Leoneans, who were ready to pay the price to absorb the secrets of the white power.This book attempts to examine the missionaries' educational work in Sierra Leone, and its effects. It aims at providing the reader with some information about how Sierra Leoneans had access to Western education.
