Targaryen and Valyrian Ancestry: Why This Lineage Matters
The Targaryen family tree is rooted in the ancient civilization of Valyria, making them one of the few surviving dragonblooded lineages in the world. As former dragonlords who conquered and ruled the Seven Kingdoms for nearly three centuries, their ancestry shapes the politics, claims, and conflicts of the realm. Understanding the Valyrian foundation, key marriages, and surviving branches helps explain the legitimacy of heritage claims and the enduring mystique of house sigils, relics, and prophecies tied to their bloodline.
Defining Valyrian and Targaryen Heritage
What Makes a House Valyrian or Dragonblooded?
Valyrian freehold was an ancient superpower built around dragons, with noble families intermarrying to preserve bloodlines. A dragonlord is traditionally someone who can bond with and ride a dragon. The Targaryens are the best-known surviving dragonblooded house, but other cadet branches such as the Velaryons and Celtigars also claim Valyrian descent. Key markers include documented descent from original dragonlords, retention of dragon artifacts or eggs, and strong interfamilial marriage practices intended to keep the bloodline pure.
Core Targaryen Genealogy and Major Branches
The main Targaryen line descends from Aenar Targaryen, who relocated his family and dragons from Valyria to Dragonstone centuries before the Conquest. From Aenar and his sibling-spouses came the direct ruling kings, ending with the death of King Daeron II and the destabilizing War of the Usurper. Important cadet branches include the Targaryens of Pentos, descendants of Maekar I’s younger son, and various exiled claimants who married into other noble houses. Houses that regularly intermarried with Targaryens include the Velaryons, Celtigars, Hightowers, and certain Reach and Storm lord families.
Key Figures and Marriages in the Family Tree
Aenar the Exile and the Founding of the Dragonlord Line
Aenar Targaryen, also known as Aenar the Exile, moved his family from Valyria to Dragonstone with five dragons, establishing a lineage that would eventually produce Aegon I. By consistently marrying brother to sister or cousin to cousin, the family preserved their dragonblood. The union of Aegon I with his sisters Visenya and Rhaenys bound the three dragons to the throne and created a clear patrilineal and matrilineal descent that shaped future claims.
Notable Marriages, Alliances, and Bloodline Blending
Strategic marriages linked the Targaryens to other dragonblooded or influential houses, blending Valyrian ancestry with regional power bases. Maegor I’s multiple wives illustrate the importance of securing loyalty through family ties. Later generations saw marriages into Stormborn houses and Reach houses, introducing non-Valyrian blood while still maintaining recognized legitimacy through paternal descent. The union of Rhaenyra Targaryen with Laenor Velaryon and later with Daemon Targaryen exemplifies how alliances reinforced both dragonblood claims and naval strength.
Comparison of Major Dragonblooded Houses
| House | Primary Region | Claim to Dragonblood | Notable Intermarriage with Targaryens |
|---|---|---|---|
| Targaryen | Westeros (capital in King’s Landing) | Direct dragonlords from Valyria; ruled the Seven Kingdoms | Primarily intrafamily marriages (sibling-cousin) |
| Velaryon | Driftmark, Crownlands | Valyrian descent through mother of the first queen | Rhaenys Targaryen married Corlys Velaryon |
| Celtigar | Crownlands (Claw Isle) | Valyrian dragonlords, sworn to Dragonstone | Married into Targaryen branches in past centuries |
| Hightower | Oldtown, Reach | No direct dragonblood; allied through service and marriage | Marriages to Targaryens for political alignment |
| Estermont | Storm’s End region | No dragonblood; minor house with strong Stormlands ties | Marriage alliances with smaller Targaryen cadet branches |
Interpreting the Family Tree for Claims and Conflicts
Legitimacy in the Seven Kingdoms often hinges on both paternal descent and historical precedent. A ruler may claim the throne through Targaryen blood on the father’s side while also seeking alliances through non-Valyrian mothers. The survival of dragon eggs and the occasional emergence of new dragons can reset expectations about who is considered a true dragonlord. Recognized heirs, bastardy, and proximity to the main branch influence which factions rally around a given claimant, making the family tree more than a genealogical curiosity—it is a map of potential power.
Cadet Lines, Exiles, and Succession Scenarios
Pentos, Exiles, and Relocated Branches
Branches such as the Targaryens of Pentos and the Exiled Targaryens preserved the name and sometimes dragonblood outside the royal line. These lines often married into Free Cities nobility or other Westerosi houses, creating hybrid claims that rarely threaten the sitting ruler but can offer safe harbors for heirs or plots. Because they lack a direct hold on throne lands or dragons, their influence is generally cultural and financial rather than military.
Modern Representation and What Survives Today
By the time of the main series, the primary Targaryen line is represented by a small number of descendants, most notably Daenerys and her siblings. The deaths of Viserys and later Daenerys leave the continuation of the main line dependent on distant cousins, rumored bastards, and possible new heirs yet to be revealed. Cadet branches, combined with rumored hidden descendants, keep the question of rightful succession alive and fertile for long-term narrative speculation.
Evaluating Legacy, Influence, and Bloodline Strength
Valyrian blood correlates strongly with resistance to fire, dragon affinity, and historically higher rates of magic, though these traits are neither guaranteed nor fully understood. The Targaryen emphasis on keeping the bloodline pure increased the visibility of their lineage but also concentrated vulnerabilities. Dragon eggs, swords, and crowns are tangible symbols that convert ancestry into political currency, while the persistence of the house name ensures that even fragmented branches remain significant in the larger story of Westeros.
