OTL during the 1960s most Quebec cities had 3 distinct school boards: French Catholic, English Catholic and English Protestant.
French Catholics were mostly descended from the original Norman-French colonists (habitants) who settled 400 years earlier.
English Catholics were mostly Irish Catholics who fled the 1840s potatoe famines back in Ireland
Meanwhile English Protestants were a mixture of British, Scottish, Scots-Irish and United Empire Loyalists. There were even a few Orange Order Protestants from Northern Ireland. English Protestants dominated the upper levels of banking, shipping, industry, etc. while the majority of French-Canadians toiled in the middle and lower classes.
The Quiet Revolution started during the 1950s after old-school Premier Jeam Duplessis retired. Centuries of oppression by the Catholic Church and British Crown lifted off the shoulders of Québécois peasants.
Left-wing political groups, hippies and trade-unionists angrily demanded dozens of radical reforms. Some trade unions became almost Marxist, striking etc. in their campaigns for better pay, better equality and opportunities for advancement.
WI Quebec suffered a civil war similar to the Spanish Civil War pitting conservatives (Catholic Church, wealthy land owners and the Army) versus reformers (lower and middle-class French Canadians)?
