How long did John Bunyan actually spend in jail due to preaching without a permit?

John Bunyan spent a significant amount of time in prison because he was imprisoned for preaching without a license. The correct answer reflects that he was incarcerated for approximately 12 years, from 1660 to 1672. This lengthy imprisonment highlights the serious consequences that dissenters faced during that era for their religious beliefs and practices, especially when they contradicted the established Church of England. Bunyan's time in jail was also pivotal for his later works, including his most famous book, "The Pilgrim's Progress," which he wrote while imprisoned. This context not only illustrates the challenges he faced but also emphasizes the impact that his experiences had on his literary contributions and his advocacy for religious freedom.
