What is the length of time John Bunyan spent in jail after preaching without a license?

John Bunyan, a prominent English writer and preacher known for his work "The Pilgrim's Progress," was imprisoned for a significant period due to his nonconformist religious activities. After preaching without a proper license, he was arrested and faced severe penalties. The correct answer, which indicates that he spent 12 years in jail, reflects the historical context of the time when dissenting religious views were not tolerated in England. This lengthy imprisonment demonstrates the extent of the religious persecution that nonconformists like Bunyan faced in the 17th century. His time in jail was not only a personal trial but also pivotal in his literary career, allowing him the time to write some of his most important works.
