A crown represents the symbol of a king. Hence it should come as no surprise that royal families from all over the world put a lot of emphasis on crowns, which are often passed over generations.
One might question since it is a family heritage, why was it not seen or used earlier in House of The Dragon? Why is Viserys wearing a different crown? What happened to Aegon the Conqueror’s crown? Let’s have a look at the crown’s journey from Aegon I’s rule to the coronation of Aegon II in House of The Dragon.
During the time of his conquest, Aegon landed with his army on the eastern coast of Westeros at the mouth of the Blackwater Rush, where he constructed the wooden Aegonfort. Aegon I died in 37 AC on Dragonstone from a stroke at the age of sixty-four. After that, his crown and the Iron Throne were passed down to Aenys I Targaryen, his son with his sister/wife Rhaenys.
After Aegon I’s death in 37 AC, his son with Rhaenys ascended to the Iron Throne. He claimed his father’s throne amidst the rubble and mud of the torn-down Aegonfort and the foundations of the Red Keep.
Aenys I dies early in the year 42 AC, after which his half-brother Maegor I usurps the Iron Throne. Maegor hated the Faith of the Seven as they had scorned his second wife, Lady Alys Harroway, who they called “Maegor’s Whore”
Jaehaerys was third in line to rule after his older brothers, Aegon and Viserys, were killed by their uncle Maegor. He could only rise to the Iron Throne after his uncle’s death, such was his cruelty and influence.
