Aegon “the Dragon” usually refers to Aegon I Targaryen , better known as Aegon the Conqueror, from the Game of Thrones / A Song of Ice and Fire universe.

Who Aegon the Dragon Is

  • Aegon I Targaryen was the first Targaryen king to sit the Iron Throne and founder of the Targaryen dynasty in Westeros.
  • His epithets include “Aegon the Conqueror” and “Aegon the Dragon,” reflecting both his Valyrian dragonlord blood and his use of dragons in war.
  • He invaded and unified six of the Seven Kingdoms (all except Dorne) using three dragons: Balerion, Vhagar, and Meraxes, alongside his sister‑wives Visenya and Rhaenys.

Why He’s Called “the Dragon”

  • Aegon was a Valyrian dragonlord from House Targaryen, a family whose sigil is a three‑headed dragon and whose power came from riding dragons.
  • He personally rode the great black dragon Balerion the Black Dread, the most feared dragon of his age.
  • His conquest by dragonfire—most famously the Field of Fire and the burning of Harrenhal—cemented his reputation as “the Dragon.”

Other Aegons and Possible Confusion

There are multiple Aegons in the lore, which is why people sometimes ask “who is Aegon the Dragon?”

  • Aegon II Targaryen : a later king who fought his half‑sister Rhaenyra in the Dance of the Dragons; he rode Sunfyre.
  • Aegon V (“Egg”) : called “the Unlikely,” a different king known from Dunk & Egg stories, not usually called “the Dragon.”

But in fan discussions and most official references, “Aegon the Dragon” = Aegon I Targaryen, the Conqueror.
