The World's Reformation: How Protestantism Became a Global Religion

By Alec Ryrie

A vivid history of how Protestantism was spread across the globe, from the sixteenth to the eighteenth century

Protestantism revolutionised early modern Europe. Radical theologians transformed the lives of thousands across the continent, irrevocably changing politics and society. But what about beyond Europe's borders? Was global Christianity just a Catholic endeavour?

Alec Ryrie explores the untold history of how Protestants tried to spread their religion abroad, from Lapland to Chile and Barbados to Taiwan. At the story's heart are the non-Christian people whom Protestants met more often than any others during this period: those they had enslaved in the Americas, Africa, and eastern Asia. We see how Protestants dealt with, or evaded, the moral failure of the slave trade, and how their missionary efforts were disappointments at best, utter fiascos at worst.

Their world Reformation, its failures, and its consequences for both good and ill, has largely been forgotten. This fascinating history makes the case for why it is worth remembering.
