Robert's Rebellion (282 AC-283 AC), also known as the War of the Usurper, was a rebellion against House Targaryen, instigated by the disappearance of Lyanna Stark. When her brother Brandon learned that she had been kidnapped by Prince Rhaegar Targaryen, he went to King's Landing to demand her return. He was arrested for threatening the life of Prince Rhaegar, and later executed along with his father, Lord Rickard Stark, and their traveling companions on the orders of King Aerys II Targaryen. Next, King Aerys commanded Lord Jon Arryn to send him the heads of his two former wards, Robert Baratheon, Lyanna's betrothed, and Eddard Stark, Brandon's younger brother, and, following the death of his elder brother and father, now the Lord of Winterfell. Jon Arryn refused, and raised his banners instead, starting the rebellion.

This led to a war which lasted close to a year, and which divided the Seven Kingdoms. Battles were fought in the Vale, the stormlands, the riverlands, and the Reach, and alliances were struck, resulting in the marriage between Eddard Stark and Catelyn Tully, and Jon Arryn and Lysa Tully. The result of the rebellion was the end of the Targaryen dynasty, which had lasted close to three hundred years, and the beginning of the Baratheon dynasty. The war included several major battles, including the Battle of the Bells, the Battle of the Trident, and the Sack of King's Landing. Read more....
