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.
At some point, Lord Tytos Lannister imprisoned Lord Walderan Tarbeck for disloyalty. In return, Lady Ellyn Tarbeck seized three Lannisters - two Lannisters of Lannisport, and Stafford, whose sister was betrothed to young Tywin Lannister. Tywin suggested that Lord Walderan should be sent back to his wife in three pieces, one for every Lannister taken, but Tytos returned Tarbeck unharmed.
A few years later, the Tarbecks rebelled again, together with House Reyne. 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 Castamere and Tarbeck Hall were put to the torch.
Tywin Lannister's actions to restore his family's power were immortalized in the song The Rains of Castamere. His ruthlessness also earned the attention of the recently crowned Aerys II Targaryen, who named him Hand of the King.
