What happened after the French revolution in Catholic religion?

Answer 1

Some priests survived, and Our Blessed Lord sent His Mother to speak to the people and offer them comfort and a way out of their difficulties, to quote the words of Our Blessed Lord, Jesus Christ, to Sister Lucia of Fatima:

"Make it know to my ministers that, given that they follow example of the king of France in delaying the execution of my request, they will follow him into misfortune."

He returned later in that same year, August 1931:

"They did not want to heed my request. Like the king of France, they will repent and do so, but it will be too late." Some did, most did not, and World War II followed on the heels of World War I, for a complete recounting of the story, please see that last chapter "1917 AD: Fatima and the Twentieth Century in Diane Moczar's book, Ten Dates Every Catholic Should Know.
