In this dazzling global history that charts five centuries of innovation and change, Alec Ryrie makes the case that Protestants made the modern world. Protestants introduces us to the men and women who defined and redefined this quarrelsome faith. Some turned to their newly accessible bibles to justify bold acts of political opposition, others to support a new understanding of who they were and what they could and should do. Above all, they were willing to fight for their beliefs. If you look at any of the great confrontations of the last five centuries, you will find Protestants defining the debate on both sides. Protestants have also fought among themselves. What unites them all is a passion for God and a vital belief in the principle of self-determination.
Protestants have set out for all four corners of the globe, embarking on courageous journeys into the unknown to set up new communities and experiment with new systems of government. They are resourceful innovators and are making new converts every day in China, Africa, and Latin America. Protestants created America and defined its special brand of entrepreneurial diligence. Whether you are yourself a Protestant, or even a Christian, you live in a world, and are guided by principles and ideas, shaped by Protestants.

Why have societies that were once overwhelmingly Christian become so secular? We think we know the answer, but in this lively and startlingly original reconsideration, Alec Ryrie argues that people embraced unbelief much as they have always chosen their worldviews: through their hearts more than their minds.
Looking back to the crisis of the Reformation and beyond, Unbelievers shows how, long before philosophers started to make the case for atheism, powerful cultural currents were challenging traditional faith. These tugged in different ways not only on celebrated thinkers such as Machiavelli, Montaigne, Hobbes, and Pascal, but on men and women at every level of society whose voices we hear through their diaries, letters, and court records.
Ryrie traces the roots of atheism born of anger, a sentiment familiar to anyone who has ever cursed a corrupt priest, and of doubt born of anxiety, as Christians discovered their faith was flimsier than they had believed. As the Reformation eroded time-honored certainties, Protestant radicals defended their faith by redefining it in terms of ethics. In the process they set 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 age.
