An Introduction to Frankism

The Hidden Messianic Movement That Challenged Judaism and Christianity

Most readers have never heard of Frankism—and that is precisely why this book is so hard to put down.

In the eighteenth century, a mysterious movement emerged that refused to fit neatly into any category. Its followers were Jewish. They followed Jesus. They accepted baptism. And yet they insisted on keeping the Law. To rabbis, they were heretics. To Christian authorities, they were deeply unsettling converts. To history, they became a problem best left unexplained.

An Introduction to Frankism finally tells their story—clearly, carefully, and without sensationalism—revealing one of the most provocative religious experiments of early modern Europe.

You’ll discover:
• How Jacob Frank transformed failed messianic hope into a radical theology of secrecy and rebellion
• Why mass conversion to Christianity strengthened the movement instead of ending it
• How Frankism used double identity, coded belief, and underground networks to survive
• The fierce reactions of Jewish and Christian authorities who struggled to contain it
• What Frankism reveals about charisma, power, and the psychology of belief

This book goes beyond dates and doctrines. It shows how religious movements actually work—how they spread, how they adapt, and why people follow leaders who promise redemption through rupture rather than comfort. Frankism is not treated as a footnote or curiosity, but as a serious challenge to authority, tradition, and identity at a turning point in Jewish and European history.

Written for curious beginners and serious readers alike, this book combines scholarly insight with clear, engaging storytelling. It sheds light on questions that still matter today: How far will people go in search of meaning? When does faith become rebellion? And what happens when belief refuses to stay within acceptable boundaries?

If you are drawn to forbidden histories, controversial religious movements, or the hidden forces that shape faith and identity, this book belongs on your shelf.
