because due to print culture there religion was in danger. Print was making the people a revolutionary against the Catholics. The news which was against the roman Catholics was dominating over the people...

Print and popular literature encouraged many distinctive interpretations of religious faiths and ideas. In the 16th century, Manocchio, a miller in Italy began to read books available readily in his locality. He gave a new interpretation of the Bible, and formulated a view of God, and creation that enraged the Roman Catholic Church.
As a result, Manocchio was hauled up twice, and ultimately executed when the Roman Church began its inquisition, and to repress the therapeutical ideas. After this several control measures were imposed on publishers and booksellers. In 1558, the Roman Church decided to maintain an Index of prohibited books.
