Quotation from: Manners, Custom and Dress During the Middle Ages and During the Renaissance Period

Written by: Paul Lacroix

The corporations and the citizens had great weight in restoring the
monarchical power, as well as in forming French nationality; but by far
the best influence brought to bear in the Middle Ages was that of
Christianity. The doctrine of one origin and of one final destiny being
common to all men of all classes constantly acted as a strong inducement
for thinking that all should be equally free. Religious equality paved the
way for political equality, and as all Christians were brothers before
God, the tendency was for them to become, as citizens, equal also in law.
