Elias C. Boudinot was the son of Elias “I Don’t Have A Middle Name” Boudinot, who’d helped to establish and edit the first Amerindian newspaper, the Cherokee Phoenix. The senior Boudinot believed acculturation (assimilation into white culture) was the best hope for the survival and success of his people. He was assassinated in 1839 for his role in Indian Removal, having signed the Treaty of New Echota convinced that a move to Indian Territory was inevitable and the Cherokee should at least secure the best terms possible.
I don’t know what it must be like to have your father assassinated by members of your tribe over violations of sacred beliefs, but I can’t imagine it does much for your love of the people or their traditions and values. I’m just speculating.
