What did William Lyon Mackenzie rebel against?
William Lyon Mackenzie rebelled against the Family Compact, which was a group of in-bred politicians that held all the political power in Upper Canada (now Ontario). They were distributing too much optimal land to the church, and their interests were for the businessmen instead of the farmers, as they should have been. Mackenzie and his followers wanted a more democratic government, like in the States. Unfortunately, their rebellion was smothered, and many men were either deported to Australia or had to flee to the States.
