Game of Thrones Targaryen Family Tree
From the Mad King’s Reign to Jon Snow’s True Parentage — The Final Generation of Fire and Blood
The complete Game of Thrones-era Targaryen family tree — Aerys the Mad King, Rhaegar, Daenerys, and the Jon Snow reveal — explained in full.
The Dynasty Restructured
The Game of Thrones Targaryen family tree covers the final generation of the dynasty before its near-total collapse — starting with the Mad King’s reign and ending with the reveal that changed everything: Jon Snow’s true parentage. Here’s exactly how everyone connects.
Era Context
This is the last stretch of the full Targaryen dynasty — roughly 15 years before Robert’s Rebellion through the show’s ending.
The Last Stand
The Final Generation of Dragons
Following the fall of Aerys II, the blood of old Valyria dispersed across Westeros and Essos. These are the main actors of the core family line.
Aerys II Targaryen
The Mad King
Last Targaryen to sit the Iron Throne before the Rebellion. Increasingly paranoid and violent, killed by Jaime Lannister ‘The Kingslayer’ of his own Kingsguard.
Queen and Sister-Wife
Rhaella Targaryen
Aerys’s wife and sister, endured his cruelty. She died giving birth to Daenerys on Dragonstone during the Great Storm.
Aerys’s Eldest Son
Rhaegar Targaryen
Aerys’s eldest son, a melancholic prince obsessed with prophecy. Killed by Robert Baratheon at the Battle of the Trident.
The Beggar King
Viserys Targaryen
Aerys’s younger son, self-proclaimed king-in-exile. Cruel and entitled, killed by Khal Drogo’s molten gold crown.
Mother of Dragons
Daenerys Targaryen
Aerys’s youngest child, born on Dragonstone during a great storm. Rose from exiled princess to Khaleesi to Queen. Dragons: Drogon, Rhaegal, Viserion.
The Hidden Heir
Jon Snow
Rhaegar’s son with Lyanna Stark, raised in secret as Ned Stark’s bastard to protect him from Robert Baratheon. True name: Aegon Targaryen.
The Secret at the Tower of Joy
Rhaegar, Lyanna & The Jon Snow Reveal
Jon Snow is not Eddard Stark’s biological son. He is the son of Rhaegar Targaryen and Lyanna Stark, born in secret at the Tower of Joy and raised as Ned’s bastard to protect him from Robert Baratheon, who would have killed any surviving Targaryen heir.
This makes Jon Snow Daenerys’s nephew — and under Targaryen succession customs, arguably the one with the stronger claim to the Iron Throne.
“Promise me, Ned.” — Lyanna Stark’s final words to Ned Stark at the Tower of Joy.
The Stormborn Empress
Daenerys Targaryen — Mother of Dragons
The last child of Aerys II, born on Dragonstone during exile after the Rebellion. Her arc — from exiled princess to Khaleesi to Queen to the show’s devastating final twist — makes her the most individually iconic Targaryen.
Her marriage to Khal Drogo and later relationship with Jon Snow (her nephew, unknowingly) are frequent points of confusion, since Targaryen customs around close-relative marriage differ sharply from most norms.

Survivor of a hundred battles. Colossal she-dragon whose roar shook the Stormlands. Second only to Balerion in size.
