Ultramontanism was a word invented to describe the Roman Catholic church in France which taught that people owed a greater loyalty to the man on the other side of the mountains than to their own government. The man on the other side of the mountains was the Pope who resided across the Alps in Rome.
The French Revolution, beginning in 1789, severely limited the influence of the Pope in France. By this time Quebec had been separated from France for 30 years, due to the English conquest and ultramontanism continued to be the orientation of the Roman Catholic church of Quebec. After the conquest, it was able to pose as the sole defender of the French Canadian language and culture. They were aided in this by a tacit agreement with English Canadian business interests that left financial affairs in the hands of the English, while the church looked after the educational, health care, religious and social needs of the population.
After two centuries this came to an abrupt end with the election of 1960 which brought to power the Quebec Liberal Party, led by Jean Lesage. In a few short years the new government had turned education, health care and social services into government responsibilities. This era is known as the Quiet Revolution.
The Roman Catholic church, stripped of most of its power to control the people, also lost most of its religious influence. Church attendance in Quebec is now the lowest of any North American jurisdiction. Churches which used to hold three or four masses Sunday morning now have one service with the church half full. Many churches have closed. Evangelical churches have grown rapidly. So have groups with bizarre and esoteric beliefs.
The people of Quebec are still determined to maintain their cultural identity, which includes but is not limited to the French language. They see themselves as a unique nation, that is, a people sharing a common language, history and culture. Not all Québecois are of French ancestry, many are English, Scottish, Irish, German, Hispanic, Italian, etc. Not all Québecois believe that as a nation they need to be a separate country. Though some politicians still promote that idea, most Québecois are nationalists, not separatists.
One effect of Québec nationalism is that woke thinking which has become the only correct way of thinking in educational institutions, media and politics in English Canada has not been able to gain quite the same foothold in Quebec. Ultramontanism is dead, but respect for prominent persons and events of the past is an essential part of nationalism.
