Aegon Targaryen in House of the Dragon is Aegon II, the eldest son of King Viserys I and Alicent Hightower, and a major claimant to the Iron Throne. He becomes central to the civil war known as the Dance of the Dragons, fighting against his half-sister Rhaenyra for the crown.

Quick Scoop

  • He is Viserys I’s firstborn son with Alicent Hightower.
  • His claim to the throne conflicts with Rhaenyra’s, who had already been named heir by Viserys.
  • In the story, he is crowned as Aegon II and becomes one of the key figures in the Targaryen civil war.
  • The show portrays him as morally flawed and politically volatile, not a simple hero or villain.

Why he matters

Aegon matters because his existence turns a family succession dispute into a full-scale war. His claim is backed by the faction later called the Greens, while Rhaenyra leads the opposing side.

Simple breakdown

  1. Born into the royal family.
  2. Chosen by his supporters as king after Viserys dies.
  3. Opposes Rhaenyra’s claim.
  4. Becomes one of the central causes of the Dance of the Dragons.

One important note

There are several Targaryens named Aegon across the franchise, but in House of the Dragon the main one is Aegon II, the son of Viserys and Alicent.

In short, Aegon is the disputed king whose claim drives the show’s main conflict.
