The Westerlands were originally a sovereign nation known as the Kingdom of the Rock, until Aegon the Conqueror arrived in Westeros and united the Seven Kingdoms. House Lannister, the richest family in the Seven Kingdoms, have ruled as the Lords of Casterly Rock for hundreds of years.
Despite Tyrion Lannister being the heir to Casterly Rock since his elder brother Jaime is a knight of the Kingsguard, Lord Tywin has made it clear that he has no intention of allowing Tyrion to be the Lord of Casterly Rock following his death. It is therefore not clear who the heir to Casterly Rock currently is.
