Restoration of Lannister dominance over the Westerlands
The Reyne-Tarbeck Rebellion was an uprising in the Westerlands. Houses Reyne and Tarbeck rose against their Lannister overlords due to the perceived weakness of the Lord of Casterly Rock, Tytos Lannister. However, Lord Tytos' eldest son, Tywin Lannister took upon himself the task of restoring his House's dominance. Taking command of the Lannister forces, Tywin marched against the upstart vassals and defeated them. By the end of the campaign both rebel houses were completely obliterated and their seats put to the torch.
Tywin Lannister's actions to restore his family's power were immortalized in the song The Rains of Castamere. His ruthlesness also earned the attention of the recently crowned Aerys II, who named him Hand of the King.
