When the printing press was invented, German printers established themselves at various important centres of western Europe, where already numbers of copyists were employed in multiplying manuscripts.
In 1473 Louis XI granted letters patent (giving the right of printing and selling books) to Uldaric Quring (Ulrich Gering), who three years earlier had set up a press in the Sorbonne (the theological faculty of the university at Paris), and before long Paris had more than fifty presses at work.
In 1496 Pope Alexander VI began to be restrictive, and in 1501 he issued a bull against unlicensed printing, which introduced the principle of censorship.
Between 1524 and 1548 the Imperial Diet in Germany drew up various stringent regulations; and in France, prohibited by edict, under penalty of death, the printing of books, This was too severe, however, and shortly afterwards the Sorbonne was given the right of deciding, a system which lasted to the Revolution.
Repression of free discussion was regarded as so necessary a part of government that Sir Thomas More in his Utopia makes it punishable with death for a private individual to criticize the conduct of the ruling power.
