A Song of Ice and Fire contains numerous examples, such as that between Stannis Baratheon and Renly Baratheon. After their eldest brother Robert Baratheon's death they contend for the Iron Throne, Stannis finally killing Renly through dark magic, though it is left unclear whether he is aware of his role in their death. The history of Westeros also contains "The Dance of the Dragons", in which Princess Rhaenyra Targaryen and her half-brother Aegon II Targaryen fought over the Iron Throne after their father Viserys I Targaryen's death, Aegon eventually killing Rhaenyra, but being poisoned shortly after, leading to Rhaenyra's son Aegon III becoming King.
