When the Black Death swept across Europe in the 14th century, it did more than decimate populations-it shook the very foundations of belief.

Plague of Faith explores the profound spiritual and institutional crisis that followed one of history's deadliest pandemics. As millions perished and entire communities vanished, the Medieval Church-long regarded as the unshakable pillar of divine order-found itself unable to answer the most urgent question of all: Why?

Through vivid storytelling and rigorous historical insight, this book traces how fear, doubt, and disillusionment spread alongside the disease. Clergy died in staggering numbers, religious authority fractured, and desperate populations turned to radical movements, superstition, and even open defiance of the Church. What had once been a unifying force began to splinter under the weight of its own limitations.

From abandoned parishes to the rise of heretical sects, from desperate acts of piety to growing skepticism, Plague of Faith reveals how the pandemic didn't just transform society-it permanently altered the relationship between people and their faith.

A gripping account of crisis and transformation, this book offers a powerful reminder: when certainty collapses, belief itself must evolve.
