Christianity has transformed many times in its 2,000-year history, from its roots in the Middle East to its presence around the world today. From the mid-twentieth century onward the presence of Christianity has increased dramatically in Asia, Africa, and Latin America, and the majority of the world’s Christians are now nonwhite and non-Western. The Encyclopedia of Christianity in the Global South traces both the historical evolution and contemporary themes in Christianity in more than 150 countries and regions. The volumes include maps, images, and a detailed timeline of key events. The phrases “Global Christianity” and “World Christianity” are inadequate to convey the complexity of the countries and regions involved—this encyclopedia, with its more than 500 entries, aims to offer rich perspectives on the varieties of Christianity where it is growing, how the spread of Christianity shapes the faith in various regions, and how the faith is changing worldwide.

In 1838, William Ellis of the LMS published a History of Madagascar―considered a key primary source for nineteenth-century Malagasy history. Four years later, David Griffiths, longest serving member of the Madagascar Mission, published Hanes Madagascar (“History of Madagascar”) in Welsh. Campbell’s study explores the intriguing relationship between these works and their authors. It analyses the role of Griffiths; presents evidence that much of Ellis’ History derived from Griffiths’ research; and presents the first ever translation of Hanes Madagascar (with extensive annotations). This study suggests that the tensions arising from the different cultural perceptions of Welsh and English missionaries moulded the destiny of the Madagascar mission. It will hopefully inspire re-evaluation of other missions and their relationship to British imperial policy.
