Rhaenyra Targaryen was a key figure in the history of the Seven Kingdoms of Westeros, featured prominently in George R.R. Martin’s “A Song of Ice and Fire” book series and the subsequent television adaptation, “Game of Thrones.” However, there is no indication that Rhaenyra was a stillborn baby.

Rhaenyra was born in 97 AC, the first child of King Viserys I Targaryen and his first wife, Queen Aemma Arryn. Viserys was the fourth Targaryen king to sit the Iron Throne, and his reign was marked by a number of conflicts and struggles for power, including the Dance of the Dragons, a civil war between Rhaenyra and her half-brother Aegon II.
According to Martin’s novels, Rhaenyra was a healthy and lively baby, and she quickly became the apple of her father’s eye. Viserys was deeply devoted to his daughter, and he even named her his heir despite the fact that he had a son, Aegon, by his second wife, Queen Alicent Hightower. This decision would have far-reaching consequences, as it set in motion the events that led to the Dance of the Dragons.
There is no mention in Martin’s books or the “Game of Thrones” television series that Rhaenyra was stillborn. In fact, there are numerous references to her birth and childhood, including descriptions of her beauty, intelligence, and fiery temperament. Rhaenyra’s mother, Queen Aemma, died when she was only six years old, and her father later married Alicent Hightower, who gave birth to several sons. This led to a bitter rivalry between Rhaenyra and her stepmother, who schemed to have her own sons named as Viserys’ heirs instead of Rhaenyra.
The question of Rhaenyra’s birth status may have arisen from confusion with another Targaryen character, Daenerys Targaryen. Daenerys was the daughter of King Aerys II Targaryen and his sister-wife Rhaella. According to the Targaryen family tree, Daenerys had an older brother named Rhaegar, who was born in 259 AC, but there is no mention of any other siblings between Rhaegar and Daenerys. However, in the television adaptation of “Game of Thrones,” Daenerys has a vision of her brother Viserys as a baby, which some viewers may have mistaken for a stillborn Rhaenyra.
In conclusion, there is no evidence to suggest that Rhaenyra Targaryen was a stillborn baby. On the contrary, the books and television series depict her as a vibrant and significant character in the history of Westeros, whose birth and upbringing were instrumental in the events that led to the Dance of the Dragons. While there may be some confusion with other Targaryen characters, such as Daenerys, there is no reason to believe that Rhaenyra’s birth was anything other than a healthy and joyous occasion for her family.
