One of the most famous examples of a sisterly conflict in Shakespeare's plays is the rivalry between Goneril and Regan in *King Lear*. These two sisters are driven by their ambition and greed to betray their father and seize power for themselves. Their conflict is ultimately destructive, leading to the downfall of both sisters and the destruction of the kingdom.
Another notable sisterly conflict in Shakespeare's plays is the relationship between Bianca and Kate in *The Taming of the Shrew*. Bianca is the younger, more beautiful and gentle of the two sisters, while Kate is the older, more headstrong and independent sister. Their conflict arises from the fact that Kate is perceived to be a shrew by the men in their society, while Bianca is seen as the ideal woman. This conflict is eventually resolved when Kate is "tamed" by Petruchio, but the play suggests that the conflict between the two sisters is far from over.
Shakespeare's plays also feature conflicts between sisters that are driven by love and loyalty. In *Cymbeline*, the sisters Imogen and Cymbeline are separated when Cymbeline marries a new wife. Imogen's stepmother plots to have her killed, and Cymbeline is forced to choose between his daughter and his wife. This conflict is ultimately resolved when Imogen is reunited with her father and Cymbeline's new wife is revealed to be a villain.
These are just a few examples of the many complex and realistic conflicts that Shakespeare draws on between sisters. By exploring these conflicts, Shakespeare reveals the complexities of human relationships and the challenges of living in a patriarchal society.
