The 1837 Lower Canadian Rebellion was as close as the Canadian colonies ever came to revolution.  Edmund Bailey O’Callaghan – doctor, politician, and notable newspaper editor in Montreal – was Louis-Joseph Papineau’s right-hand man in the tense years leading to the battles between les patriotes and the British Army.  As the editor of The Vindicator, O’Callaghan became the most powerful Irishman in Montreal, trying to create a Canadian republic through the power of his printing press.
