Targaryen family marriage custom

Targaryen family marriage custom joined two political purposes: marriages within the royal house preserved its distinctive dynastic practice, while matches with other noble families helped connect distant regions and secure alliances. The custom shaped the production of heirs, the negotiation of loyalty, and disputes over who could inherit the Iron Throne; it also met resistance from the Faith of the Seven, whose leaders never formally accepted the royal marriages between close kin as lawful.

Dynastic Practice and Religious Tension

Aegon I Targaryen took both his sisters, Visenya Targaryen and Rhaenys Targaryen, as wives. Each bore him a son, establishing the first generation of royal heirs through the family’s own marriage practice. The custom extended beyond sibling unions: the book describes Targaryens as marrying brothers to sisters and cousins to cousins, and notes that Prince Aenys married Alyssa Velaryon, a match regarded as one between cousins because both families had Valyrian ancestry.

The practice sat uneasily beside the Faith’s teachings. During Aegon’s reign, High Septons maintained courteous relations with the king but did not declare his marriages to his sisters lawful. Many ordinary members of the Faith continued to regard a brother’s marriage to his sister, or a man’s taking of two wives, as sinful. Royal practice therefore persisted without resolving the religious question, leaving a tension beneath the public accord between the Iron Throne and the Faith.

Marriage as an Instrument of Alliance

Royal marriage-making was not confined to the Targaryens. Aegon’s queens arranged matches intended to bind noble houses from different parts of the realm. Ronnel Arryn, Lord of the Eyrie, married a daughter of Torrhen Stark of Winterfell, while Loren I Lannister’s eldest son married a Redwyne girl from the Arbor. When the Evenstar of Tarth had triplet daughters, Rhaenys arranged betrothals linking them to House Corbray, House Hightower, and House Harlaw.

Visenya also used marriage to reconcile long-standing rivals. She arranged a double wedding between House Blackwood and House Bracken, matching a son of each family with a daughter of the other in an effort to seal peace between houses whose hostility stretched back centuries. Rhaenys’s intervention extended beyond great houses: when a girl from House Rowan serving her became pregnant by a scullion, the queen found the girl a husband in White Harbor and arranged for a knight in Lannisport to foster her child. These cases show marriage operating as a means of managing relationships across rank as well as territory.

The same alliance-making could be negotiated as a direct political exchange. At White Harbor, Desmond Manderly recalled an old promise linking his house to the royal family: Jaehaerys I Targaryen had offered his daughter Viserra to Manderly’s ancestor, but Viserra died and the promise was forgotten. In a later negotiation during the conflict over the crown, Jacaerys Velaryon agreed that his brother Joffrey would marry Manderly’s youngest daughter after the war. The marriage was prospective, but the compact made clear that dynastic ties could be offered to secure support.

Heirs, Betrothals, and Succession

Marriage also shaped the order of succession. When Aenys and Alyssa’s daughter Rhaena was born, Visenya proposed betrothing the infant to Maegor, who was eleven. Aenys and Alyssa opposed the match, and the High Septon warned Aegon that the Faith would not look upon it favorably. The proposal was thus entangled with two questions at once: whether Maegor stood ahead of Rhaena in the succession, and whether a close-kin marriage could be accepted by the Faith. Maegor instead married Ceryse Hightower in the Starry Sept, with the High Septon officiating.

Later, Aenys and Alyssa’s marriage produced a line of children that included Rhaena, Aegon, Viserys, Jaehaerys, and Alysanne. Aenys’s marriage to Alyssa was described as happy and fruitful; their daughter Rhaena’s birth brought public celebration, while also prompting renewed uncertainty over Maegor’s place in the succession. Under Jaehaerys, the death of Prince Aemon raised a related problem: Aemon’s daughter Rhaenys was married to Corlys Velaryon and was pregnant when her father died, yet Jaehaerys named Aemon’s brother Baelon heir. The king’s choice followed established practice favoring a male claimant, but it passed over Rhaenys and potentially her unborn son. Marriage connected the royal line to House Velaryon; it did not guarantee that a woman or her child would inherit.

The custom continued in the next generation. In 122 AC, Viserys married his son Aegon the Elder to his daughter Helaena, following the ancient Targaryen tradition. Their children, including twins Jaehaerys and Jaehaera and later Maelor, gave Aegon heirs of his own. In the succession crisis that followed Viserys’s death, Otto Hightower’s concern about the precedent of the Great Council of 101 reflected the continuing political force of male-preference succession: absent a trueborn son, the king’s brother could be held to precede his daughter. Royal marriage produced heirs, but inheritance customs and political decisions determined how their claims were ranked.

The Custom Beyond the Royal House

The evidence also connects the custom to the origins of the dragonseeds. On Dragonstone, Targaryen men sometimes sought relationships with the daughters or wives of smallfolk. The right of the first night had once been invoked there more often than elsewhere, and children born of such unions were regarded as dragonseed; after that right ended, some Targaryens continued to have relationships with innkeepers’ daughters and fishermen’s wives, leaving numerous seeds and descendants. These people became politically important when Jacaerys called on men of Targaryen blood to claim dragons, promising lands, wealth, knighthood, and elevated prospects for their children.

Across the generations, the custom was therefore more than a private household convention. Close-kin marriages sustained the royal line, marriages between houses offered ways to make alliances or reconcile enemies, and relationships beyond the nobility created descendants who could later be drawn into dynastic conflict. Those functions did not remove the custom’s costs or controversies: religious disapproval persisted, proposed matches could become succession disputes, and marriage alliances could make a family’s claim consequential without ensuring that it prevailed.
