The French government.
After the Revolution secular education was begun in France.
It had dislodged the old social order, overthrown the monarchy, and brought the church under state control.
It was the French citizen who was opposed by the Royalty and the Catholic Church.
The political power of France after the French Revolution was in the hands of the Republican Government, the Military, the Catholic Church and the Peasants who had created the Revolution. There was also a Royalist minority that always pushed for a restoration.
Many were sacked and looted. Some were converted into warehouses and markets.
They confiscated all of the Catholic Church property and sold it to help ease the French debt.
The First Estate.
There is only one Catholic Church, and all ordained priests were members of it before the revolution.
The French revolution was extremely hostile to the Catholic Church. They guillotined priests, nuns, and sisters by the hundreds, desecrated Churches, and destroyed priceless relics; leaving the common people bereft of spiritual guidance and solace.
Ummm... you've heard of the French Revolution, right? The terror, the guillotine, etc? that is the effect anticlerical sentiment had on France.
Because it was a declaration by the people of France that they were in control and the days of the Ancient Regime, special treatment of nobles because of the accident of birth and the power of the Catholic Church were relics of the past.
During the French Revolution, the monarchy lost their heads. France became a Republic for the First time. France is now in the fifth republic.
