Check le gars qui donne un coup d'épée dans l'eau parce qu'il pense qu'il détient la vérité à propos de notre histoire. lol
The basic principles of the rebellions were for responsible government with elected officials who represented with accountability vs the Colonial Style of Government with appointed leaders by a monarch that never stepped foot on the soil. Reasons very similar to what the US had fought for. While it's a complex subject and we can go on for hours with different subjects Political Reform was the largest cause.
The British could have ethically cleansed Upper and Lower Canada as they had done and did elsewhere. We need to look at why they didn't
1. Resources were stretched thin for the British. They were tangled up elsewhere in other ventures of colonialism or battling some other country. Stabilizing the "situation" here was paramount. At first they didn't budge but after the US gained or should I say announced independence they quickly Passed the Quebec Act. Which restored French Civil Law and religious freedom.
2. Money. The British after losing the USA was bleeding cash and suffering from lack of raw goods... Timber was a huge issue to the British... See Royal Navy. What did Canada have? Lots of Timber.. just one example of goods. Then just as today fighting wars across an ocean cost money,... Stuff like beaverpelts and junk were our of fashion and most didn't give a crap about. Timber, Iron Ore, copper and tin were the money makers...
Back then it took months to reinforce and supply. It would cost a ton of ton of cash and resources. The French population wasn't really causing headaches so why bother?
3. A loyal French population could be called upon to quell any invasion from the USA when needed. The British knew the USA would skirmish into Canada. The Americans were actually less trusted than the British by the French population . The French population defended brilliantly from Americans.
4. Just as today wars were somewhat unpopular. Who wants to die defending some place they never heard of or seen? Worse the British were paranoid about a possible rebellion on their own soil due to the all wars and social class system. For years France had been the natural enemy of the British and were defeated at Quebec... Why bother fighting another war there with a local population that outnumbered the British but as I said weren't causing too many problems... This isn't even taking into the account the Natives and their various wars or conflicts going on.
It gets to the point though where the people want to self govern and not want to be under the umbrella of a legislative assembly across an ocean.
The ramifications of the French Population accepting the status quo changed and built up into a full scale melt down by the end of the 60s. I don't think the English are solely to blame throughout the years. It certainly didn't help that guys like Duplessis for example ruled his population with an iron fist and kept most of the population in a miniature dark age... Then the Parti Quebecois having no real economic platform which didn't help matters.
The narrative most believe is that it's a language issue. However it's always been a political acceptance struggle or "Hey look at me" from not just Quebec but RoC.
