How does "domination" present itself throughout the novel Invisible Man by Ralph Ellison?

Domination presents itself in numerous episodes throughout the novel. You might look at the exchange between the narrator and Dr. Bledsoe, the Battle Royal, the narrator's feeling of tokenism when he joins the mostly white Brotherhood, the narrator's manipulation of Sybil, and the ideological battle between the narrator and Ras the Destroyer.
The Battle Royal is the most salient example of domination in the novel, so I will focus on that. It is also a chapter in the book in which Ellison illustrates how both race and gender ensure the domination of white men and the subordination of everyone who does not share this identity.
During the battle, a group of black men are blindfolded and led into a ring where they are to beat each other senseless in exchange for gold coins—which, the narrator later realizes, are worthless tokens. The white men who have organized the battle and who are its spectators tempt the young black men with money they will never have. This act is symbolic of how white men control wealth and only provide others with the illusion that they can obtain a similar bounty.
The men also introduce a nude blonde white woman whose face is painted like that of a "kewpie doll." She dances, and the black men are forced to watch her while hiding their arousal. This is symbolic of the way in which white men have used white women and their sexuality to control both black men and white women, thereby ensuring white men's social and sexual dominance over both groups.
In the end, the narrator is left standing. He is allowed to give his speech, inspired by Booker T. Washington's politics of self-reliance and segregation, and receives a briefcase as well as a scholarship to a historically black college which Ellison modeled on his own alma mater, the Tuskegee Institute.
