The dramatic story of Christianity from its origins to the present day, told through more than one hundred stunning color maps.

With over two billion practicing believers today, Christianity has taken root in almost all parts of the globe. Its impact on Europe and the Americas in particular has been fundamental. Through more than one hundred beautiful color maps and illustrations, Christianity traces the history of the religion, beginning with the world of Jesus Christ. From the consolidation of the first Christian empire—Constantine’s Rome—to the early Christian states that thrived in Ireland, Ethiopia, and other regions of the Roman periphery, Christianity quickly proved dynamic and adaptable.

After centuries of dissemination, strife, dogmatic division, and warfare in its European and Near Eastern heartland, Christianity conquered new worlds. In North America, immigrants fleeing persecution and intolerance rejected the established Church, and in time revivalist religions flourished and spread. Missionaries took the Christian message to Latin America, Africa, and Asia, bringing millions of new converts into the fold.

Christianity has served as the inspiration for some of the world’s finest monuments, literature, art, and architecture, while also playing a major role in world politics and history, including conquest, colonization, conflict, and liberation. Despite challenges in the modern world from atheism and secularism, from scandals and internal divisions, Christianity continues to spread its message through new technologies while drawing on a deep well of history and tradition.

“How has unbelief come to dominate so many Western societies? The usual account invokes the advance of science and rational knowledge. Ryrie’s alternative, in which emotions are the driving force, offers new and interesting insights into our past and present.”
—Charles Taylor, author of A Secular Age

Why have societies that were once overwhelmingly Christian become so secular? We think we know the answer, pointing to science and reason as the twin culprits, but in this lively, startlingly original reconsideration, Alec Ryrie argues that people embraced unbelief much as they have always chosen their worldviews: through the heart more than the mind.

Looking back to the crisis of the Reformation and beyond, he shows how, long before philosophers started to make the case for atheism, powerful cultural currents were challenging traditional faith. As Protestant radicals eroded time-honored certainties and ushered in an age of anger and anxiety, some defended their faith by redefining it in terms of ethics, setting in motion secularizing forces that soon became transformational. Unbelievers tells a powerful emotional history of doubt with potent lessons for our own angry and anxious times.

“Well-researched and thought-provoking…Ryrie is definitely on to something right and important.”
—Christianity Today

“A beautifully crafted history of early doubt…Unbelievers covers much ground in a short space with deep erudition and considerable wit.”
—The Spectator

“Ryrie traces the root of religious skepticism to the anger, the anxiety, and the ‘desperate search for certainty’ that drove thinkers like…John Donne to grapple with church dogma.”
