It use to be the Milwaukee Braves, and before that the Boston Braves - named after - what for it - the Brave “Indians” in the Boston tea party. Sorry, this is about patriotisms, not Indians.
For a while, they were the Boston Bees. Before that, the Beaneaters.
BTW, part of Braves Field in Boston still stands. it’s Nickerson Field at BU. The old Braves ticket office is the BU Police Station.
