Defining the Targaryen Succession Line
The Targaryen succession line begins with Aegon I Targaryen, who conquered and unified the Seven Kingdoms three centuries before Robert’s Rebellion. As the first king, he established the royal bloodline and defined inheritance customs that shaped centuries of conflict. Over generations, the line produced pivotal rulers such as Jaehaerys I, the Long Peace, and the turmoil of Aerys II, whose weak rule precipitated the dynasty’s collapse. This guide explains how the succession operated through male-preference primogeniture, the impact of dragons and faith, and how each claimant’s legitimacy influenced the fate of Westeros.
Core Lineage and Legal Succession Customs
Targaryen succession followed modified male-preference primogeniture: elder sons and their male descendants typically inherited before younger brothers and their lines. In practice, the throne passed from father to son whenever possible, but civil wars and regencies exposed ambiguities when heirs died or legitimacy was questioned. The Faith of the Seven and Valyrian customs both influenced claims, with marriage customs, polygamy, and sibling unions shaping who was considered a lawful heir. Stability depended on clear recognition by lords, the Small Council, and the broader realm; when recognition faltered, claimants turned succession into a contest of force and legitimacy.
Foundations: Aegon I and the Dawn of the Line
Aegon I forged the succession line by claiming Westeros as his birthright and legitimizing his rule through conquest and divine favor. He named his eldest son as heir, embedding the expectation that Targaryen kings would pass to the eldest surviving son. This precedent endured through multiple peaceful successions, embedding the idea that the Iron Throne should pass within the bloodline. Customary practices such as coronation by the High Septon and formal homage from the realm reinforced legal and symbolic continuity across generations.
Middle Period: Stable Succession and the Long Peace
Under Jaehaerys I and Alysanne, the Targaryen succession stabilized with a clear, predictable line from king to prince to grandson. Their reforms and long reign minimized succession crises, as heirs were publicly acknowledged and prepared for rule. The realm benefited from strong councils and peaceful transitions, demonstrating how legitimacy, preparation, and broad acceptance could sustain orderly succession. This era stands as a benchmark for stable hereditary rule in Westerosi history.
Key Succession Crises and Contested Claims
Several pivotal episodes reveal how succession disputes can destabilize a realm. The Dance of the Dragons showcased the dangers of ambiguous designations, with Rhaenyra and Aegon II both claiming the throne. Robert’s Rebellion reframed succession through conquest and popular revolt, casting Aerys II as a tyrant and elevating a foreign claimant. Later, the Sons of the Harpy and Daenerys’s campaigns illustrated how fragmented legitimacy and external support shape perceived rightful rule during prolonged uncertainty.
The Dance of the Dragons: Heirs and Civil War
King Viserys I named his daughter Rhaenyra heir, but upon his death, Westeros fractured. A faction crowned Aegon II, Viserys’s son by his second wife, arguing male heirs should precede sisters. The resulting civil war devastated the realm and eroded faith in Targaryen succession. Neither side could secure universal recognition, demonstrating how unclear succession laws invite rival claimants and prolonged violence. The aftermath reshaped inheritance norms and caution around ambiguous designations.
Robert’s Rebellion and Aerys II
When Aerys II alienated the realm, Robert Baratheon’s rebellion ended the Targaryen rule through conquest. By killing Aerys and displacing his son Viserys, Robert reframed legitimacy via victory rather than lineage. This created a contested succession where the rightful heir under Targaryen law—young Prince Viserys—lacked the power to enforce his claim. The shift from dynastic to conquest-based legitimacy endured until Daenerys reasserted the old claims, highlighting how succession theories compete with de facto power.
Verification and Historical Records
Reliable details on Targaryen succession come from maesterly histories, royal decrees, and trial records compiled across centuries. Contradictions exist, especially around claims of insanity, marriage validity, and the legitimacy of certain heirs. Cross-referencing texts from different houses, along with timelines of coronations and councils, helps distinguish widely accepted facts from regional bias or propaganda. Treating contested moments as areas of uncertainty ensures a fact-first understanding of what can be verified and what remains disputed.
Fact Summary: Select Succession Milestones
| Date or Period | Event | Why It Matters |
|---|---|---|
| DC 1 | Aegon I conquers Westeros; coronated as king | Establishes the Targaryen succession line |
| DC 37–52 | Jaehaerys I and Alysanne’s reign | Long Peace; orderly succession sets precedent |
| 129–133 AC | Dance of the Dragons | Heirs Rhaenyra and Aegon II both claim throne; civil war |
| 283–298 AC | Robert’s Rebellion; Aerys II deposed | Conquest overthrows dynastic succession; Viserys becomes claimant |
| 300–303 AC | Daenerys asserts claim across Essos and Westeros | Restores Targaryen legitimacy through conquest and dragons |
Heirs, Claimants, and Their Legal Arguments
- Aegon I: Chose heir through conquest and explicit designation, founding dynastic continuity.
- Jaehaerys I: Long-reigning, stable succession established peaceful norms and minimized challenges.
- Rhaenyra Targaryen: Designated heir by Viserys I; contested by Aegon II on grounds of male precedence.
- Aegon II Targaryen: Ascended by acclamation of Kingsguard and lords; fought half-sister for recognition.
- Prince Viserys: Legitimate heir under Targaryen law after Robert’s Rebellion, but lacked resources to enforce claim.
- Daenerys Targaryen: Reasserted ancient claim with dragons and foreign support, briefly restoring dynastic aspirations.
How Inheritance Customs Shaped the Line
Targaryen inheritance blended Valyrian traditions with Westerosi expectations, often allowing princesses to rule when no competent brother existed. Marriages—occasionally between siblings—were used to consolidate bloodlines, while the Faith’s influence encouraged anointment and coronation as sacred acts. When multiple heirs emerged, regional loyalties, military support, and propaganda determined who was recognized. The flexibility of these customs explains why succession outcomes varied and why seemingly weak claims sometimes prevailed through force and persuasion.
Enduring Lessons from Targaryen Succession
The Targaryen succession line offers timeless insights into how legal theory, legitimacy, and power intersect. Clear rules, recognized heirs, and peaceful transitions promote stability; ambiguity invites contestation and civil strife. The repeated impact of dragons, foreign alliances, and popular revolt demonstrates that succession is as much about perception and capability as it is about blood. Modern readers can draw parallels to any hereditary or institutional succession, where designations, customs, and enforcement shape outcomes for generations.
