Aegon I Targaryen

Aegon I Targaryen was the dragonlord who conquered most of Westeros and founded the Targaryen monarchy there. His rule turned victory into a durable political settlement: he demanded obedience to a single crown, yet preserved much of the local order and drew former enemies into its government. The contrast between the fire that won his realm and the compromises that kept it is central to his legacy.

Origins and the Dragonlord

Aegon was born on Dragonstone in 27 BC, the only son and second child of its lord and Lady Valaena of House Velaryon, who was herself half Targaryen. His elder sister was Visenya Targaryen; his younger sister was Rhaenys Targaryen. In keeping with Valyrian custom, he married both sisters. Taking two wives was unusual even by that tradition, which would ordinarily have paired him with Visenya alone. Some accounts attributed the first marriage to duty and the second to desire, but Aegon remained faithful to both sisters.

All three had established themselves as dragonriders before their marriages. Balerion, the Black Dread, was the sole survivor of the five dragons brought from Valyria by Aenar the Exile; Vhagar and Meraxes had hatched on Dragonstone. Balerion later carried Aegon in war and on swift journeys, but the king did not use his dragon for display or sport. Though counted among the greatest warriors of his age, Aegon avoided tournaments and melees and took no pleasure in feats of arms. He wielded the Valyrian steel sword Blackfyre, yet his military reputation rested less on a taste for personal combat than on the power he could command.

Aegon’s interest in Westeros preceded the invasion. The Painted Table, carved at his command as a great map of the continent, showed its woods, rivers, towns, and castles. Accounts also place him and Visenya Targaryen at the Citadel in Oldtown in their youth, and report that he went hawking on The Arbor as a guest. The claim that he first set foot on Westerosi soil when he sailed to conquer it is therefore contradicted by the record of his earlier attention to the kingdoms he would later unite.

Conquest and the Making of a King

When Aegon called his allies to Dragonstone, his following was small. On the seventh day, ravens carried a single declaration across Westeros: there would henceforth be one king. Those who submitted would retain their lands and titles; those who resisted would be defeated. Aegon then landed with his sisters and a modest force at the mouth of the Blackwater Rush, where the settlement that became King’s Landing stood among wooded hills and old ruins.

The submission he demanded was backed by the capacity to destroy resistance. At Harrenhal, Aegon warned the ironborn king who ruled there that his line would end with the setting sun. Aegon then took Balerion high above the clouds and descended within the castle’s walls. The dragon’s fire consumed the fortress and killed the king and his remaining sons. The next day, outside the smoking ruins, Edmyn Tully swore fealty. Aegon made him Lord Paramount of the Trident, and the other riverlords paid homage to their new king and their new liege lord. The episode marked both the terrifying force of conquest and the swift creation of a replacement political order.

Aegon’s authority was made visible through public ritual as well as victory. At the Aegonfort, the crude stronghold on Aegon’s High Hill, defeated lords laid down their swords; Aegon restored their lands and titles, while granting new honors to loyal supporters. Orys Baratheon, his companion from youth, became his trusted right hand and the first King’s Hand. A red three-headed dragon on a black field served as Aegon’s battle standard, a heraldic emblem that made the dragonlords legible within Westerosi custom. Visenya Targaryen placed a ruby-studded Valyrian steel circlet on his head, and Rhaenys Targaryen proclaimed him king before the assembled lords, knights, and smallfolk.

The conquest’s religious and political recognition was consolidated at Oldtown. After Lord Hightower submitted without a fight, the High Septon anointed Aegon with the seven oils in the Starry Sept and proclaimed him king of the Andals, the Rhoynar, and the First Men, lord of the Seven Kingdoms, and protector of the realm. This second coronation drew hundreds of lords and the Citadel’s maesters and archmaesters; tens of thousands cheered Aegon as he rode through the city on Balerion. The Oldtown ceremony, rather than the first crowning at the Blackwater, became the accepted beginning of his reign. Dorne, however, had not submitted, despite the royal style claiming the Seven Kingdoms.

Governing a Conquered Realm

Aegon’s rule was not simply a continuation of conquest by other means. He relied on his small council and his sisters in the ordinary work of government, but took command when he judged it necessary. Former enemies who bent the knee could expect a different treatment from rebels who continued to resist: Aegon dealt harshly with rebellion, but confirmed submitted lords in their holdings. That combination made submission a route back into political life rather than permanent dispossession.

Reconciliation also shaped the composition of the court. Aegon encouraged former foes to send younger sons and daughters to serve there. Boys became pages, cupbearers, and squires; girls served as handmaidens and companions to the queens. In King’s Landing, these members of other regions’ noble households saw royal justice at close range and were encouraged to understand themselves as subjects of one realm, not only as people of their own kingdoms. The court thus offered both a practical means of securing loyalty and a setting in which a common political identity could be learned.

The royal family also used marriage to connect noble houses across regional and historic divisions. Ronnel Arryn married a daughter of Torrhen Stark, and the heir to Casterly Rock married a Redwyne girl. Rhaenys Targaryen arranged betrothals linking the daughters of the Evenstar of Tarth to House Corbray, House Hightower, and House Harlaw. Visenya Targaryen arranged a double marriage between House Blackwood and House Bracken, whose enmity stretched back centuries, to help secure peace between them. These matches extended the work of unification beyond the battlefield and into the next generation.

Aegon traveled to learn the kingdoms he governed. During royal progresses, feasts, balls, hunts, and hawking accompanied his visits, but he also held court wherever he was, from a lord’s castle to a stone in a farmer’s field. Six maesters traveled with him to advise on local laws, customs, and history and to record his judgments and decrees. His approach to law was generally conservative: existing systems of inheritance and succession, feudal structures, and local lordly powers remained in place. Rather than impose a single detailed code, he sought to make different legal traditions operate beneath one crown.

Peace, Revenue, and the Royal City

Aegon made the suppression of private warfare a central royal responsibility. Before his accession, conflicts between kingdoms and neighboring lords were frequent. Under his settlement, lesser lords and landed knights were expected to bring disputes to their liege lords, while the Crown adjudicated quarrels between great houses. Aegon declared the King’s Peace the first law of the land and treated any lord who waged war without royal leave as a rebel and enemy of the Iron Throne. The policy made royal authority a mechanism for settling disputes as well as a power to command armies.

He also regularized customs, duties, and taxes across the realm, where previously ports and individual lords could impose varying charges. At the same time, he exempted the holy people of the Faith and their lands and possessions from taxation, and affirmed the Faith’s own courts’ authority to try and sentence its religious members accused of wrongdoing. Aegon was not known as a particularly pious man, but he consistently sought the support of the Faith and the High Septon of Oldtown. His settlements therefore combined administrative standardization with accommodations intended to preserve the allegiance of an important institution.

The city around his court grew from the fishing village at the Blackwater mouth where he had landed. The first fort, the Aegonfort, expanded as the royal household outgrew its rough defenses: a tall wooden keep and longhall, a stone kitchen roofed with slate, stables, a granary, and a higher watchtower were added, followed by further defenses. The rise of King’s Landing gave the new monarchy a permanent center at the site of its founding conquest. Its growth also made visible how a temporary landing place and military camp had become the seat of a kingdom-wide government.

Dynastic Legacy

Aegon’s marriages joined the dynasty’s political future to the question of succession. Both queens bore him a son: Aenys, born to Rhaenys Targaryen, and Maegor, born to Visenya Targaryen. Aenys later married Alyssa Velaryon, the daughter of the Lord of the Tides, in 22 AC. Their marriage was described as happy and produced several children, including Rhaena, Viserys, Jaehaerys, and Alysanne. Those births continued the royal line while also renewing the close dynastic connection with House Velaryon.

The succession of Aegon’s descendants would prove contested. At the Great Council of 101 AC, the lords chose Viserys Targaryen by a lopsided margin over the claim advanced for Laenor Velaryon. Many thereafter treated the decision as a precedent against a woman inheriting the Iron Throne or transmitting a claim to her male descendants. That later rule was not itself a decree of Aegon’s, but it belonged to the political legacy of the dynasty he founded: the crown he had made a single institution remained powerful enough that its inheritance became a defining question for generations.

Aegon’s decisive achievement was to bind conquest to practices that could outlast the conqueror: submission with restored titles, royal arbitration, a court drawn from across the realm, marriages between rival houses, and shared symbols of kingship. His dragons could compel obedience, but his arrangements gave the conquered kingdoms ways to participate in the new order. The realm remained marked by unresolved divisions, above all Dorne’s refusal to submit, yet the crown and institutions established under Aegon gave later rulers a framework for treating the Seven Kingdoms as one political realm.
