The Disadvantages of Targaryens Marrying Their Relatives

The Gods flip a coin when a Targaryen is born

The Targaryen family, known for their vibrant past and dragon heritage, also suffered significant disadvantages due to their tradition of marrying close relatives. This practice was not without its drawbacks, affecting both their health and the stability of their realm, highlighting a number of profound risks and consequences.

The Tradition of Incestuous Marriages

The Targaryens' preference for inbreeding was a controversial and often criticized tradition. Many fans and scholars argue that this custom may have led to multiple miscarriages and natural abortions. For instance, there are theories that objections to Danaerys Targaryen bearing a healthy child might not only stem from her youth but also from the potential genetic issues resulting from inbreeding. This practice was so pervasive that it was perceived as a sin by Westerosi standards, considered a taboo by the First Men and the Andals alike.

Immediate Health Consequences

The saying, "The Gods flip a coin when a Targaryen is born," underscores the unpredictability and high mortality rates associated with Targaryen life. Aenys I, for example, suffered from numerous health issues attributed to the political and familial turmoil caused by his marriage to his sister, Rhaena. His reign was marked by both internal strife and external threats. Despite Jahaerys I's effort to establish a Doctrine of Exceptionalism to exempt Targaryens from the religious restrictions of Westeros, intermarriages continued to pose significant challenges.

Political and Social Consequences

The political ramifications of inbreeding were severe. Marriages between siblings not only undermined the cohesion of the Targaryen family but also weakened their alliances. If two siblings had instead married into noble houses, their father could have gained the support of two powerful houses, thereby strengthening his claim to the throne. Instead, such marriages led to the suppression of the Faith Militant uprising, ultimately resulting in further instability.

Mental and Physical Health Issues

The mental and physical health consequences of inbreeding were devastating. The practice of marrying relatives led to an increased likelihood of madness and other genetic disorders affecting the Targaryen family. Some Targaryen infants even exhibited symptoms like scales and wings, which were believed to be remnants of their dragon heritage. The inbreeding depression, similar to what is seen in other species, led to a weakening of the gene pool and a general decline in the health and prosperity of the Targaryen family.

Conclusion

The Targaryens believed that marrying close relatives would help maintain their power and prestige, yet history shows that this practice had significant negative consequences. The tradition ultimately weakened the Targaryen family, leading to political instability and physical and mental health issues. While their unique status as a dragon-descended family might have excused their deviation from conventional marriage practices, the evidence suggests that this tradition should be seen as a cautionary tale for any noble house contemplating such a risky and potentially disastrous practice.
