House of the Dragon Family Tree: Complete Guide to the Targaryen Bloodline

The house of the dragon family tree is one of the most fascinating and complex family lineages in fantasy television. Based on the works of author George R. R. Martin, House of the Dragon explores the rise and internal conflicts of House Targaryen nearly 200 years before the events of Game of Thrones. The story centers on royal succession, dragon-riding nobles, and a civil war that reshaped the history of Westeros.

As the series continues to attract viewers worldwide, understanding the Targaryen family tree has become essential for following the relationships, alliances, and rivalries that drive the story.

What Is House Targaryen?

House Targaryen is a royal dynasty that originated from the ancient civilization of Valyria. Known for their silver hair, purple eyes in the books, and ability to bond with dragons, the Targaryens conquered Westeros under the leadership of Aegon the Conqueror.

For generations, the family maintained power through strategic marriages, often marrying within the family to preserve their Valyrian bloodline. This tradition created an intricate web of relationships that plays a central role in House of the Dragon.

The Origins of the Targaryen Dynasty

The foundation of the family tree begins with:

Aegon I Targaryen (Aegon the Conqueror)

Aegon united the Seven Kingdoms and established the Iron Throne. He was married to both of his sisters:

  • Visenya Targaryen
  • Rhaenys Targaryen

Their descendants continued the royal line that eventually led to the events depicted in House of the Dragon.

King Jaehaerys I Targaryen and Queen Alysanne

One of the most important branches of the house of the dragon family tree comes from King Jaehaerys I, often known as “The Old King.”

Jaehaerys and Queen Alysanne had numerous children, creating multiple branches of the Targaryen dynasty. Their descendants became central figures in the struggle for succession that sparked the Dance of the Dragons.

Among their descendants were:

  • Prince Baelon Targaryen
  • Prince Aemon Targaryen

These lines ultimately led to the major characters featured in the television series.

King Viserys I Targaryen

At the center of the story stands King Viserys I Targaryen.

First Marriage: Queen Aemma Arryn

Viserys married Aemma Arryn and had:

  • Princess Rhaenyra Targaryen

Rhaenyra was named heir to the Iron Throne, a decision that would later divide the kingdom.

Second Marriage: Queen Alicent Hightower

After Aemma’s death, Viserys married Alicent Hightower. Together they had:

  • Aegon II Targaryen
  • Helaena Targaryen
  • Aemond Targaryen
  • Daeron Targaryen

The children from Viserys’ second marriage became rivals to Rhaenyra’s claim to the throne.

Princess Rhaenyra Targaryen’s Branch

Rhaenyra is one of the most significant figures in Targaryen history.

Marriage to Laenor Velaryon

Rhaenyra married Laenor Velaryon and had three sons:

  • Jacaerys Velaryon
  • Lucerys Velaryon
  • Joffrey Velaryon

Although questions surrounded their parentage, they were officially recognized as Velaryons.

Marriage to Daemon Targaryen

Following later events, Rhaenyra married her uncle Daemon Targaryen.

Their children included:

  • Aegon III Targaryen
  • Viserys II Targaryen

Both sons would eventually play major roles in the future of House Targaryen.

Prince Daemon Targaryen’s Branch

Daemon Targaryen, brother of King Viserys I, is among the most influential members of the family.

Marriage to Lady Rhea Royce

This marriage produced no children.

Marriage to Laena Velaryon

Daemon and Laena had:

  • Baela Targaryen
  • Rhaena Targaryen

Both daughters inherited strong Targaryen and Velaryon bloodlines.

Marriage to Rhaenyra Targaryen

This union strengthened Rhaenyra’s political position and expanded the royal family tree even further.

Alicent Hightower’s Family Line

Alicent’s children became leaders of the faction known as the Greens.

Aegon II Targaryen

Aegon II challenged Rhaenyra’s claim and became a central figure during the Dance of the Dragons.

Helaena Targaryen

Helaena married her brother Aegon II, continuing the Targaryen tradition of family marriages.

Their children included:

  • Jaehaerys
  • Jaehaera
  • Maelor

Aemond Targaryen

Aemond became one of the most feared dragon riders in Westeros and played a major role in the civil war.

Daeron Targaryen

Daeron contributed significantly to the Green cause during the conflict.

The Velaryon Connection

The Velaryon family is closely tied to the Targaryens.

Important Velaryon figures include:

  • Corlys Velaryon
  • Rhaenys Targaryen
  • Laenor Velaryon
  • Laena Velaryon

These marriages linked two of the most powerful Valyrian houses in Westeros.

The Dance of the Dragons and Family Divisions

The Targaryen civil war known as the Dance of the Dragons erupted because competing branches of the family claimed the Iron Throne.

The Blacks

Led by:

  • Rhaenyra Targaryen
  • Daemon Targaryen
  • Jacaerys Velaryon

  • Rhaena Targaryen

The Greens

Led by:

  • Alicent Hightower
  • Aegon II Targaryen

  • Daeron Targaryen

The conflict devastated the Targaryen dynasty and greatly reduced the number of dragons in Westeros.

How the Family Tree Connects to Game of Thrones

Generations later, the family produced notable figures such as:

  • King Aerys II Targaryen
  • Prince Rhaegar Targaryen

This direct connection makes House of the Dragon a crucial chapter in the larger history of Westeros.
