"Dance of the Dragons" refers to a civil war in the fictional world of Westeros, part of George R.R. Martin's A Song of Ice and Fire series. This conflict occurred between the Targaryen factions, primarily the supporters of Princess Rhaenyra Targaryen and Prince Aegon II Targaryen, over the Iron Throne. The war was marked by intense battles, political intrigue, and the use of dragons. The war began in 129 AC and lasted for several years, leading to significant losses on both sides. The conflict ultimately resulted in the weakening of the Targaryen dynasty and the near extinction of their dragons, shaping the future of Westeros and its ruling families.
