2020 brings readers the 400th anniversary of the sailing of the Mayflower--the ship that took the Pilgrim Fathers to the New World. It is a foundational event in American history, but it began as an English story, which pioneered the idea of religious freedom.

The illegal underground movement of Protestant separatists from Elizabeth I's Church of England is a story of subterfuge and danger, arrests and interrogations, prison and executions. It starts with Queen Mary's attempts to burn Protestantism out of England, which created a Protestant underground. Later, when Elizabeth's Protestant reformation didn't go far enough, radicals recreated that underground, meeting illegally throughout England, facing prison and death for their crimes. They went into exile in the Netherlands, where they lived in poverty--and finally to the New World.

Historian Stephen Tomkins tells this fascinating story--one that is rarely told as an important piece of English, as well as American, history--that is full of contemporary relevance: religious violence, the threat to national security, freedom of religion, and tolerance of dangerous opinions.

This is a must-read book for anyone interested in the untold story of how the Mayflower came to be launched.
