Every Aegon Targaryen In Game Of Thrones (From Aegon The Conqueror To Jon Snow)

by

HBO recently added another character named Aegon to the world of A Song of Ice and Fire in the third episode of A Knight of the Seven Kingdoms. With Jon Snow and other Targaryens throughout Westerosi history, there are now eleven in total, which can make it tricky to keep track of them all.

The latest book in the A Song of Ice and Fire series, A Knight of the Seven Kingdoms, revealed that a character named Egg is secretly Aegon Targaryen. This means that every book published so far in the series has included at least one character with the name Aegon Targaryen, as it was a popular name—particularly for firstborn sons—among Targaryens due to its connection to the original Targaryen conqueror.

This list covers every character named Aegon who appears in the world of Game of Thrones, from the very first Aegon the Conqueror to Jon Snow, drawing from both the TV series and George R.R. Martin’s books.

Every Aegon in the Game of Thrones Universe

Aegon the Conqueror

Aegon Targaryen, known as Aegon the Conqueror, earned his title by traveling to Westeros on a massive dragon and successfully conquering six of the seven kingdoms – though he never managed to take Dorne. This victory established him as the undisputed king. According to the stories, Aegon had a prophetic dream about the White Walkers and the coming Long Night, believing it was his duty to unite the land and prepare for battle against them.

As a huge fan of the series, it’s always fascinated me how the prophecies played out. While the big fight against the Night King and the White Walkers didn’t happen during Aegon the Conqueror’s time, his vision still came true. It turned out a Targaryen – Jon Snow, as we learned – would eventually bring most of Westeros together to battle the army of the dead. It’s a clever echo of history, really.

Aegon the Uncrowned

Aegon the Conqueror had a son named Aenys Targaryen, who later became king. Aenys’s first son was also named Aegon, but he never ruled. When Aenys died, his uncle, Maegor the Cruel, seized the throne instead of allowing Aegon to become king.

Aegon didn’t accept Maegor taking the throne without a fight. However, he was defeated, and Maegor ultimately killed him during a dragon battle. Because Aegon never actually ruled as king, he became known as Aegon the Uncrowned.

Aegon, Son of Jaehaerys I

Fans who watched the first episode of House of the Dragon Season 1 will likely recall King Jaehaerys I Targaryen. In that opening scene, Jaehaerys formally chose Paddy Considine’s Viserys Targaryen as his successor.

Jaehaerys had thirteen children, but sadly, many didn’t live long. One son, Aegon, died just three days after his birth. Interestingly, Jaehaerys’ brother was also named Aegon, meaning Jaehaerys had both a brother and a son with the same name. This other Aegon is known as Aegon the Uncrowned.

Aegon, Brother of Viserys and Daemon

The series House of the Dragon introduces Viserys I and Daemon Targaryen as brothers. Their father, Baelor, actually had three sons. After Daemon was born, Baelor had another son named Aegon Targaryen, but tragically, like the son of Jaehaerys, this Aegon died very young.

Aegon II Targaryen (Aegon the Elder)

Aegon II Targaryen is the oldest child of King Viserys Targaryen and Alicent Hightower. He became king and led the Greens during the events depicted in House of the Dragon. The series also showed that Viserys chose the name Aegon based on a vision he had just before he died.

This core belief was the root cause of the conflict known as the Dance of the Dragons, the Targaryen civil war depicted in House of the Dragon. In Season 3 of House of the Dragon, Aegon II will reappear and continue his battle with his half-sister, Rhaenyra, for control of the Iron Throne.

Aegon III Targaryen (Rhaenyra’s Son)

Rhaenyra notably named one of her sons Aegon Targaryen, and he too would eventually become king. As fans of Game of Thrones know, Aegon III was forced to witness a horrific event: Aegon II’s dragon, Sunfyre, killing Rhaenyra. This tragic moment is expected to happen in House of the Dragon as well.

As a huge fan of the Targaryen history, it’s always struck me how Aegon II actually let Aegon III live after the Dance of the Dragons. Because of that, when Aegon II finally died, the throne went to Aegon III. It was a tough break for him, though, because he then had the enormous task of rebuilding almost all of Westeros after the devastation of the war.

Aegon IV Targaryen (Rhaenyra’s Grandson)

Aegon IV Targaryen was the son of Viserys II, who was himself the son of Rhaenyra and Daemon. When Viserys died, Aegon became king, but he’s remembered as one of the most difficult and troublesome rulers in Westeros’ history.

Aegon IV wasn’t just corrupt and immoral – before he died, he also legally recognized all of his illegitimate children. This decision caused the Blackfyre Rebellions in the world of Game of Thrones, and it’s a conflict that Egg, a character in A Knight of the Seven Kingdoms, will eventually face.

Aegon V Targaryen (Egg)

In the third episode of A Knight of the Seven Kingdoms, it’s revealed that Egg isn’t just any boy – he’s actually a Targaryen prince. Because he’s a distant fourth son of a fourth son, his chances of becoming king were incredibly slim. This is why, when he eventually does become king, he’s known as Aegon the Unlikely.

Aegon V’s reign was marked by significant events, including the Blackfyre Rebellions, the births of key characters in Game of Thrones, and the devastating Tragedy at Summerhall. He’s generally considered a good king, particularly by common people, because his decisions as ruler often improved their lives.

Aegon Targaryen (Brother of Daenerys)

Most fans are familiar with Aerys Targaryen – often called the Mad King – and his children Rhaegar, Viserys, and Daenerys. However, it’s less well known that he had other children as well, including one named Aegon.

Like some of the other Aegons on this list, Aegon, son of Aerys, died while he was still an infant.

Aegon Targaryen (Young Griff?)

Do you remember the intense fight between Pedro Pascal’s Oberyn Martell and the Mountain in Season 4 of Game of Thrones? That fight was largely motivated by Aegon Targaryen. Elia Martell, Oberyn’s sister, was married to Rhaegar Targaryen, and they had a son named Aegon, as Rhaegar strongly believed in the prophecy of ‘The Prince That Was Promised’.

At the conclusion of Robert’s Rebellion, the Mountain tragically killed Aegon, along with his sister and mother, Elia. But that wasn’t the only son of Rhaegar to be called Aegon.

In George R.R. Martin’s novels, a character called Young Griff asserts he is Aegon Targaryen, the true heir to the Iron Throne. This storyline was completely left out of the Game of Thrones TV series. With Martin’s The Winds of Winter still unpublished, fans are left wondering about Young Griff’s fate and whether he’s actually who he claims to be.

Aegon Targaryen (Jon Snow)

A major surprise in Game of Thrones happened during the episode “The Winds of Winter.” Amidst a series of shocking events, the music dramatically built as the camera switched from a baby to Jon Snow. It was then revealed that the baby was the son of Lyanna Stark, Ned Stark’s sister, and Rhaegar Targaryen.

Jon’s true name, Aegon, wasn’t revealed until Season 7. It’s somewhat amusing that Rhaegar named two of his sons Aegon, but given his strong belief in the Prince That Was Promised prophecy, it actually fits his thinking.

With Daenerys dead, Jon Snow became the last Targaryen – unless you subscribe to theories about Tyrion Lannister’s parentage, or are still reading the books and haven’t discovered the identity of Young Griff. It’s somewhat poetic that the first significant Targaryen was named Aegon, and so was the last.
