It is true that my Beloved Blackhawks (originally Black Hawks) were named for a WWI military unit, that had adopted it's name from a defeated Sac and Fox tribal member, who was viewed as a brave war leader. So, indirectly, the team is named, not for a people or a race, but for a single historical figure,
Ma-ka-tai-me-she-kia-kiak (Be a large black hawk).
Through the years, I had read many opinions from Sac and Fox members that are glad that the team name keeps some of their history alive.
The 'Hawks themselves have, through the years, made an effort to reach out to the peoples from whom the team name derived...
