Aegon II (left) & Rhaenyra Targaryen (right)

The Targrayens were doing really good as rulers of the 7 Kingdoms despite having continuous conflict with Dorne. There was no one who could oppose them, and the dragons still used to live. However, during the reign of Viserys I Targaryen, there was a dispute between two potential heirs to the Iron Throne: Aegon II and his older half-sister Rhaenyra.

Rhaenyra was a brave woman and worthy of ruling Westeros. However, Aegon II despite being younger was made the Lord of Seven Kingdoms, and this led to a war- a civil war where brothers fought brothers, dragons fought dragons, nicknamed by the singers as the Dance of Dragons. Read why Robert's Rebellion wasn't House Targaryen's fall, this Civil War was here.

This war was the beginning of the end for House Targaryen and the Targaryens never truly recovered from the losses this Civil War bought with it. But who won this Civil War?

The Targaryen Civil War was won by Aegon II who killed his sister Rhaenyra with his dragon Sunfyre. Aegon II went on to be a good king afterwards, being one of the Targaryens who didn't go mad.
