King Jaehaerys I Targaryen, also known as Jaehaerys the Conciliator, Jaehaerys the Wise, and the Old King, was the second son of Aenys I who rose up against his uncle Maegor I the Cruel after the death of his brother Aegon, who had usurped the Iron Throne. Jaehaerys took the crown from his uncle and married his younger sister, Alysanne. He had thirteen children, and his descendants continued to ascend the throne, although Jaehaerys outlived any of his sons. He was officially referred to as Jaehaerys of House Targaryen, the First of His Name, King of the Andals and the First Men, Lord of the Seven Kingdoms and Protector of the Realm.

He generally wore fine white clothes, richly ornamented with gold. His own crown was golden and bore the Targaryen sigil in the center and those of other Great Houses around it, made to represent the harmony he brought to the realm as the fourth to sit on the Iron Throne.[2]

The youngest son of Aenys I and Queen Alyssa, Jaehaerys was born near the time of the Faith Militant uprising, an event that caused succession problems when his uncle Maegor usurped the throne from Jaehaerys' older brother, Aegon, after Aenys I died on Dragonstone due to the stress of the recent revolts. Having remained hidden and out of reach along with his sister Alysanne during the conflict, Jaehaerys would witness the unfolding of the war from afar and the ascension of his uncle, much to the discontent of the kingdom.¹

Reign of Maegor I and ascension
When Aegon died, Maegor I married Rhaena Targaryen, Aegon's widow and also Jaehaerys' older sister. She was forced to become one of Maegor's Brides in Black as he was having trouble bearing an heir. When the Faith Militant rose again, several noble lords began to support not only its revolts, but also Jaehaerys' ascension in place of his uncle, who had earned the nickname "the Cruel". Rhaena managed to escape with her dragon Dreamfyre and joined Jaehaerys and Alysanne's dragons, Vermithor and Silverwing respectively.[3]
When Maegor I was found dead on the Iron Throne, Jaehaerys I ascended the throne and made peace with the Faith of the Seven, disarming the Faith Militant once and for all and permitting incestuous marriages only within the Targaryen line.[1]
