The Popes Against Modern Errors: 16 Papal Documents
In 1789, the French Revolution took place and launched a host of religious, political, and social errors which the Popes for over 160 years wrote and legislated against.

But almost from the beginning of these errors, the Popes spoke out as with one voice, inveighing against them.
