The civil war that ended Targaryen rule, also called the War of the Usurper. Triggered when Prince Rhaegar Targaryen abducted (or eloped with) Lyanna Stark, and Mad King Aerys murdered Rickard and Brandon Stark, the rebellion united Houses Baratheon, Stark, Arryn, and Tully against the crown. Robert Baratheon killed Rhaegar at the Battle of the Trident, and Jaime Lannister slew the Mad King. Robert took the throne and married Cersei Lannister. The war's unresolved secrets - particularly the truth of Lyanna and Rhaegar's relationship - have consequences that echo throughout the series.
