1628-1688. English author. A Baptist, he was imprisoned in Bedford 1660-72 for unlicensed preaching. During a second jail sentence in 1675 he started to write Pilgrim's Progress, the first part of which was published in 1678. Other works include Grace Abounding 1666, The Life and Death of Mr Badman 1680, and The Holy War 1682. At 16, during the Civil War, he was conscripted into the Parliamentary army. Released in 1646, he passed through a period of religious doubt before joining the Baptists in 1653. In 1660 he was committed to Bedford county jail for preaching, where he remained for 12 years, refusing all offers of release conditional on his not preaching again. During his confinement he wrote Grace Abounding describing his early spiritual struggles. Set free in 1672, he was elected pastor of the Bedford congregation, but in 1675 was again arrested and imprisoned for six months in the jail on Bedford Bridge, where he began The Pilgrim's Progress. The book was an instant success, and a second part followed in 1684.
