The Taming of The Shrew by Shakespeare and Oroonoko by Aphra Behn show similarities of the use of power. In The Taming of The Shrew we see how Baptista uses his power to wed his daughters and have wealthy men bid for the opportunity to marry into the family while in Oroonoko we see how the prince Oroonoko along with others who have power mistreat those without.
We learn how Katherine is left with the choice of marrying or staying at home under her father’s control while in Oroonoko, although not in full detail, we learn about the abuse of slaves. Oroonoko who fights to prevent his child from becoming a slave takes part in the slave trade market himself.
The use and the misuse of power allows for individuals to be corrupt in order to get what they want.
When you say that Oroonoko mistreats those who have no power, you need to provide a specific citation from the text that supports that claim. There may indeed be a similarity between the way women are married to the highest bidder in The Taming of the Shrew and the depiction of the slave trade in Oroonoko, but you haven’t provided evidence of it.
