Family history:

The maternal ancestry can be traced back to the most legendary liar in the Age of Heroes: the clever Lenny, who is said to have cost him nothing. In one fell swoop, Casterly Rock was captured from the Casterly family with nothing more than cunning. The paternal bloodline comes from the Andal adventurers who established a powerful kingdom among the canyons and hills. Later, the Lannister family was the King of Casterly Rock for generations.

After Laurent Lannister, the last King of Casterly Rock, surrendered to Aegon after a disastrous defeat in the Battle of the Wilderness, the Lannister family has been hereditary guardian of the West and Lord of Casterly Rock. There is a branch in Lannisport. The gold mines produced at Casterly Rock and the Golden Tooth made the Lannisters the richest family in the Seven Kingdoms.

During the reign of Tytos Lannister, his weakness brought the reputation of House Lannister to its lowest point. The Tarbeck and Reyes families even openly rebelled, and their son Tywin Lannister led troops to suppress them and destroy the two families. "The Rains of Castamere" has since been spread. After Tywin Lannister came to the throne, he quickly restored his family's power and served as the Hand of Aerys II.

The former King of Casterly Rock Tommen II once took his Light Howling Sword to explore Valyria, but never returned, and the whereabouts of the Light Howling Sword have been unknown ever since. The Lannisters are always looking for replacements, such as Tywin Lannister, who repeatedly tried to buy the Valyrian swords of some impoverished houses for huge sums of money, but was rejected.

The Lannister family remained stationary during the Usurper's War. It was not until the outcome of the war was decided that they joined Robert Baratheon's side and used a strategy to invade King's Landing.
