In the booksEdit
In the A Song of Ice and Fire novels, Aegon III watched as his mother was devoured by the dragon of Aegon II, his uncle, during the civil war known as the Dance of Dragons. Due to the trauma of witnessing his mother's death, Aegon III developed a fierce hatred and terror of the creatures.
Aegon III ascended to the Iron Throne after Aegon II died without any males heirs. He married Aegon II's daughter (and only surviving child) Jaehaera to seal the peace between the two rival branches of House Targaryen. However, she later died without issue, ending Aegon II's line entirely. Aegon III then remarried to Daenaera of House Velaryon, who was the mother of all of his subsequent children.
Aegon III ascended to the Iron Throne when he was only eleven years old, making him the youngest king in history - until Tommen Baratheon ascended the throne at the age of eight (the TV series aged-up several child characters, so TV-Tommen is actually slightly older than eleven, though even so TV-Tommen came to the throne very young). The early years of his long reign, until he reached the age of majority at sixteen, were a tense period known as the Regency. A regency council was organized with members who fought on both sides in the civil war, a measure taken to ensure peace, given that neither side was truly victorious. Ser Tyland Lannister (who served his grandfather Viserys I as Master of Ships, and later as the Green Master of Coin under Aegon II) became Hand of the King. Tyland served for two years before dying of a winter chill. Lady Jeyne Arryn, ruler of the Vale and one of the core Black leaders, also served on the regency council. When Aegon III reached maturity he began to rule in his own right and named his brother Prince Viserys Hand of the King.
Aegon III ruled the Seven Kingdoms long and well, repairing the extensive damage wrought by the civil war. Aegon III is nonetheless often blamed for the death of the last dragon, for which he became known as "Aegon the Dragonbane", despite his later efforts to obtain Dragon eggs. At some point he had nine mages cross the sea to attempt to hatch his remaining cache of eggs. So few dragons had survived the civil war that they could not maintain a stable breeding population. Only four dragons had survived the Dance: Silverwing, the Cannibal, Sheepstealer (who was missing and presumed dead), and one other (who only hatched late in the war). The dragons were inbred to begin with, descending only from the original three brought to Westeros by Aegon I and his sisters. The final two dragons were hatched and then died during Aegon III's long reign: they were stunted, sickly creatures not much bigger than large dogs, and they did not live long. Some speculate that the Maesters poisoned the last dragons, because as men of science and learning they feared and hated the magical powers associated with the creatures. It is unknown if this was true, but the maesters certainly had no great love for the dragons and welcomed their demise when it came.
Aegon had two sons: Daeron, called the Young Dragon, and Baelor, called Baelor the Blessed. He also had three daughters, later known as the "Three Maidens in the Tower": Daena the Defiant, Rhaena and Elaena. Upon his death in 157AL, Aegon III was succeeded by his young son Daeron. Aegon was said to have always walked with a great grief, and the folly of his sons nearly tore the realm apart.
Both of Aegon III's sons ruled as king but both died without issue. Afterwards, due to the new succession laws Aegon III had enacted, his three daughters were skipped over, and his younger brother Viserys II was crowned king. Therefore later Targaryens such as Daenerys do not descend from him. However, his daughter Daena had a love affair with Viserys II's son King Aegon IV, which produced Aegon IV's bastard son Daemon Blackfyre. Aegon IV legitimized him on his deathbed, after which Daemon founded House Blackfyre. Thus the later Targaryens descend from younger brother Viserys II, while the Blackfyres illegitimately descend from older brother Aegon III (as well as, also illegitimately, from Viserys II's son Aegon IV).
