The term "ultramontanism" was revived during the French Third Republic (1870–1940) as a pejorative way to describe policies that went against "laïcité" a concept rooted in the French Revolution. The French philosopher Jacques Maritain noted the distinction between the models found in France and the separation of church and state in the United States in the mid-twentieth century. He considered the US model of that time to be more amicable because it had both "sharp distinction and actual cooperation" between church and state, what he called "an historical treasure" and admonished the United States, "Please to God that you keep it carefully, and do not let your concept of separation veer round to the European one."
