The literary tradition of Birmingham originally grew out of the culture of religious puritanism that developed in the town in the 16th and 17th centuries. Birmingham's location away from established centres of power, its dynamic merchant-based economy and its weak aristocracy gave it a reputation as a place where loyalty to the established power structures of church and feudal state were weak, and saw it emerge as a haven for free-thinkers and radicals, encouraging the birth of a vibrant culture of writing, printing and publishing.
