Viserys I Targaryen was king of Westeros from 107 to 130 AC, a reign defined by efforts to secure a smooth succession in a dynasty built on blood marriage and fragile lines. This guide explains his immediate family, his place in the broader Targaryen tree, and how his choices shaped the future of House Targaryen. We trace his marriage, his children, and the rival claims that emerged after his death, focusing on genealogical facts and relationships rather than speculation. The text below clarifies how Viserys I connects to major figures such as Aemma, Aegon II, Rhaenyra, and Daemon, and why those links matter to the long arc of Targaryen history.
Immediate Family of Viserys I
Viserys I belonged to the main Targaryen branch that ruled from Dragonstone to King’s Landing after Aegon I’s conquest. His parents were both Targaryen, preserving the family’s tradition of controlled marriages to maintain "the blood" believed to protect their dragons. His marriage to Aemma of House Arryn produced a daughter, and later marriage to Alicent Hightower added more heirs. Understanding these unions helps clarify competing claims to the throne after Viserys I died.
Marriage to Aemma Arryn
Viserys I’s first wife was Aemma Arryn, a union meant to secure a reliable heir. Their only surviving child was Princess Rhaenyra, born late in Viserys I’s reign. Aemma died in childbirth, a loss that pushed Viserys I to seek a new marriage to produce additional heirs. The circumstances of Rhaenyra’s birth and status as a lone daughter from this marriage made her pivotal to succession planning.
Marriage to Alicent Hightower
After Aemma’s death, Viserys I married Alicent Hightower, bringing the Hightower influence into the core of the Targaryen court. From this marriage came three sons—Aegon II, Aemond, and Daeron—as well as a daughter, Helaena. These children created a rival line to Rhaenyra’s claim and contributed directly to the fractures that led to open conflict after Viserys I’s death.
Children of Viserys I
The children of Viserys I form the next generation of Targaryen rulers and claimants. Rhaenyra, Aegon II, Aemond, Daeron, and Helaena each played major roles in the mid-century conflicts known as the Dance of the Dragons. Their legitimacy, order of birth, and the impact of their parents’ marriages are central to understanding how the Targaryen civil war unfolded.
- Rhaenyra Targaryen: Daughter of Viserys I and Aemma Arryn; designated heir and later claimant crowned in opposition to Aegon II.
- Aegon II Targaryen: Elder son of Viserys I and Alicent Hightower; crowned king immediately after Viserys I’s death, rivaling Rhaenyra.
- Aemond Targaryen: Younger son of Viserys I and Alicent Hightower; known for his aggression and role in the Dance of the Dragons.
- Daeron Targaryen: Son of Viserys I and Alicent Hightower; his early death removed him from succession disputes.
- Helaena Targaryen: Daughter of Viserys I and Alicent Hightower; later Queen Consort to King Aegon III after the war.
Ancestry and Broader Lineage
Viserys I was the grandson of King Jaehaerys I and Alysanne, a long-reigning pair whose policies shaped the realm. His father, Aenys I, and mother, Alyssa Velaryon, continued the direct line. This ancestry matters because it situates Viserys I within a generational framework of Targaryen governance, dragonlord identity, and the customs that bound family and rule together. His siblings and cousins further populated the court and expanded the family’s reach across the Seven Kingdoms.

The Lineage Tree Structure
Viserys I sits between the long reign of his grandfather Jaehaerys I and the civil war of his children. His brother, Prince Daemon, was a key military figure whose marriages also added complexity to succession claims. On his mother’s side, the Velaryons brought naval strength and their own network of influence. Mapping these connections shows why so many houses and individuals had stakes in who would follow Viserys I after 130 AC.

Succession and the Dance of the Dragons
The question of who would inherit the throne became a direct result of how Viserys I organized his family. His initial designation of Rhaenyra as heir conflicted with the later-born sons from his Alicent marriage, leading to competing claims, oaths, and ultimately war. The dance of dragons was not only a succession crisis but also a family crisis, pitting parent against child, spouse against spouse, and blood against law in a struggle that reshaped the realm.
Legacy and Historical Assessment
Viserys I’s legacy is tied to his attempt to balance dynastic continuity with practical succession. By securing a daughter as primary heir and then fathering multiple sons, he created conditions for fracture. His reliance on oaths, betrothals, and public recognition could not fully overcome the political and personal ambitions within his own family. The long-term impact of his choices is evident in the decades of conflict that followed, as descendants of both Rhaenyra and Aegon II fought over the Iron Throne.
