A number of Shakespeare's plays display incidences of sibling rivalry. King Lear provokes rivalry among his three daughters by asking them to describe their love for him; in the same play, Edmund contrives to force his half-brother Edgar into exile. In The Taming of the Shrew, sisters Kate and Bianca are shown fighting bitterly. In Richard III, the title character is at least partially motivated by rivalry with his brother, King Edward. In As You Like It, there is obvious sibling rivalry and antagonism between Orlando and Oliver, and also between Duke Frederick and Duke Senior.

Jacob tricks his brother Esau out of his inheritance; sisters Leah and Rachel compete for the love of Jacob; Joseph's brothers are so jealous that they effectively sell him into slavery.
In East of Eden (John Steinbeck) the brothers Cal and Aron Trask are counterparts to Cain and Abel of the bible story.
