The Church Roots of Censorship

The term imprimatur is a formal mark of approval required by the Catholic Church to print books. This practice began alongside the invention of the printing press to control the flow of new ideas and ensure theological accuracy.

Emerging in cities like Venice and across Germany, this system was an early form of state-sanctioned media oversight. While we often think of modern censorship as a political tool, it was once a standard way to verify that a book met religious standards. Many secular governments eventually adopted similar registration rules to manage information. Today, the term is used more broadly to describe any official stamp of endorsement.
