Areopagitica is the most famous of Milton's prose works because it has outlasted the circumstances of its original publication. On June 14, 1643, the English Parliament passed a law called the Licensing Order, which required that all books be approved by an official censor before publication, and on November 23, 1644, Milton wrote Areopagitica, pleading for the repeal of the law. His arguments were not successful-official censorship of books in England lasted until the nineteenth century-but Areopagitica has long been an inspiration for those demanding a free press. In fact, its arguments against censorship are nearly as fresh and convincing today as they were in the middle of the seventeenth century.
