Mackenzie was born in Dundee and emigrated to Upper Canada (now Ontario) in 1820, where he became a newspaperman and radical politician. In 1834 Mackenzie became first mayor of Toronto, but in 1836 reformers were routed in Assembly elections. During 1837 Mackenzie organized armed demonstrations, but lost control of events. Rebellion broke out on 4 December. Mackenzie escaped to the USA, but an amnesty enabled him to return to Canada in 1849.
