This chapter discusses Christian missions from 1500-1900 during the age of European exploration and colonial expansion. It covers the growth of Catholic missions under royal patronage in places like India, China, and the Americas. It also discusses the beginnings of Protestant missions with pioneers like Lutherans in Suriname and Anglicans in North America. The late 18th century saw a renewed focus on missions with the founding of groups like the Baptist Missionary Society and growth of missionary societies in the "Great Century" of 1800-1914 when thousands of missionaries were sent worldwide.
