Overview of the Targaryen house
The Targaryens are a Valyrian dragonlord family that survived the Doom and founded House Targaryen in Westeros. Their narrative arc centers on the promise that their lineage would produce the prince that was promised, blending dragon power with claims to the Iron Throne. This explainer maps core ancestry, succession patterns, and pivotal events that shaped their enduring influence across the book series and television show.
Founders and Valyrian origins
House founding before the Doom
House Targaryen originates from the Valyrian Freehold, one of forty dragonlord families who settled the island of Dragonstone roughly a century before the Doom. Their survival of the Doom, combined with timely relocation to Westeros, positioned them as a unique repository of dragons and bloodline legacy.
- Origin: Valyrian Freehold, Dragonstone refuge
- Dragons: Their most distinctive trait and source of power
- Precursor status: Few bloodlines trace direct descent from pre-Doom dragonlords
Key members in the main succession line
The core succession runs from the Valyrian founders through Aegon I and his sister-wives, shaping the realm for centuries. Understanding this line clarifies claims to the throne, succession conflicts, and the promise central to Targaryen mythology.
| Name | Verified detail | Why it matters |
|---|---|---|
| Valyrian founders | Dragonlord family from Valyria | Source of bloodline and dragon legacy |
| Aegon I Targaryen | First Targaryen king, unified six kingdoms | Established the dynasty and dragon rule |
| Visenya & Rhaenys | Aegon’s sister-wives, queens in their own right | Enabled the Conquest and set precedents for female agency |
| Maegor I Targaryen | Aegon I’s son, known as Maegor the Cruel | Illustrates early succession strife and harsh rule |
| Jaehaerys I | Long reign, relative peace, council governance | Marked a stable period and matured institutions |
| Viserys I Targaryen | Divided succession led to civil war after death | His choices triggered the Dance of the Dragons |
| Aegon II Targaryen | Rival king during the Dance | Symbol of fragmentation and the cost of disputed succession |
| Rhaenyra Targaryen | Heir declared by Viserys I, claimant in the Dance | Her claim shaped legitimacy debates and succession precedents |
| Aegon III Targaryen | Firstborn of Rhaenyra post-Dance, ended the dragons | Marked the close of the dragon era |
| Daenerys Targaryen | Exiled princess who reclaimed dragons | Revived Targaryen power and fulfilled prophecy motifs |
| Viserys Targaryen | Brother of Daenerys, claimant until his death | Highlighted legitimacy issues and familial tension |
| Jon Snow | Claimant through Rhaegar and Lyanna Stark |
Significant cadet branches and relations
Several offshoots and marriage alliances extend the family tree and affect regional politics, especially in the Stormlands and beyond. They underscore how dynastic ties reshape power structures long after the main line fades.
Baratheon line (stormlands branch)
Orys Baratheon, rumored to be Aegon I’s half-brother, founded House Baratheon. This connection ties Stormlands governance closely to the Targaryen royal line for generations.
- Orys Baratheon: Founder, possibly Aegon’s brother
- Stannis & Renly: Key claimants during the War of the Five Kings
- Shireen: Child’s compassion humanized the family
Other houses tied by marriage or claims
- Velaryons: Close allies with marriage links
- Hightowers: Allied yet rival interests in King’s Landing
- Martells: Dornish independence and complex loyalties
- Tullys: Riverlands allies through strategic marriages
Notable patterns in Targaryen succession
Targaryen history shows repeated struggles over rightful rule, often triggered by ambiguous naming or contested capacity. Recognizing these patterns helps interpret conflicts from the Dance of the Dragons to the War of the Five Kings.
- Sibling marriage and polygyny to keep bloodlines controlled
- Declared heirs disrupted by father’s death without clear order
- Use of prophecies (prince that was promised) to frame legitimacy
- Dragons as both military advantage and symbolic authority
- Civil wars when succession is unclear or power centralizes too fast
Legacies and turning points
The family’s influence shifts from absolute rule to near extinction and symbolic revival. Each era reshapes perceptions of Targaryen legitimacy, whether through conquest, council governance, or prophecy-driven restoration.
| Period | Event | Why it matters |
|---|---|---|
| ~10,000 years before Aegon I | Valyrian dragonlord culture | Pre-Doom prestige and power base |
| ~259 years before Aegon I | The Doom of Valyria | Catastrophe that ended Valyrian dominance |
| 2 BC–1 AC | Aegon’s Conquest and coronation | Unified six kingdoms under dragon rule |
| 129–131 AC | Dance of the Dragons | Civil war over succession, loss of dragons |
| 283–284 AC | The War of the Usurper (Robert’s Rebellion) | |
| 298–300 AC | Daenerys’s return with dragons | |
| Post-300 AC | Show era aftermath and legacy debates |
Common questions and clarifications
- Are all Targaryens dragonriders? No; dragon affinity appears in specific individuals, not the whole family.
- Does the prince that was promised refer only to Daenerys? Interpretations vary; some link it to Jon Snow or broader themes of renewal.
- How reliable are the show’s genealogy visuals? They capture major relationships but omit some background branches and simplified naming in places.
- Is the Targaryen line functionally extinct? Biologically diminished after the Dance and Robert’s Rebellion, yet legacy and claims persist through survivors and revived dragons.
How to interpret these connections
When tracing the Targaryen family tree, prioritize primary in-world sources and corroboration across mediums. Treat prophecies and titles as in-universe beliefs that shape politics, not as external proof. Remember that exile, marriage, and contested legitimacy continuously redefine what it means to be Targaryen across centuries.
