The Targaryen dynasty was a royal family in the fictional world of Westeros, created by author George R.R. Martin in his series, "A Song of Ice and Fire." They originated from the island of Dragonstone and were known for their distinctive silver hair and purple eyes. The Targaryens are famous for their dragons, which they used to conquer and rule the Seven Kingdoms of Westeros. The dynasty began with Aegon the Conqueror, who united the kingdoms and established the Iron Throne. Over the centuries, the Targaryens faced numerous challenges, including civil wars like the Dance of the Dragons and conflicts with other noble houses. Their reign ended with the Mad King, Aerys II Targaryen, who was overthrown during Robert's Rebellion.
