FIRE AND BLOOD : The war of heirs I

The War of heirs or Dance of the Dragons was a civil war during Targaryen rule of the Seven Kingdoms. A war of succession between Aegon II and Rhaenyra over their father Viserys I's throne, the war was fought from 130 AC to 132 AC. Dragon for Dragon Aegon's claim was based on the fact that he was the first born male of King Viserys while Rhaenyra's claim was based on the fact that Viserys had named her heir to Dragonstone and the Iron Throne and that King had supported this decision until his last breath.

The birth of Rhaenyra's three daughters seemed to ease tensions, Visenya II Targaryen, first born, heir to the queen, pearl of the kingdom and ward of King Viserys. She was loved by everyone, from Queen Alice who voted for her and from Prince Aemond for whom she represented a debt in exchange for her eye. The princess had taken everything from her father Prince Daemon Targaryen, unstable and protective of her family.
Aemma II, the rebel princess, had everything her mother valued, she was the first female swordsman in Westeros, promised to Aegon (crazy in love with the princess) she had been sent by Visenya and daemon to sit on the green councils and monitor them, she had been called "black spy" during the dance.
Lyanna Targaryen, the People's Princess. She loved living in the lower world, abandoned herself to royal tasks and offered her possessions to the people, which had been a great advantage during the dance, she had been promised to Lord Cregan Stark.
For several years everything seemed to be going well, but in 129 Ac, the death of Ser Harwin Strong at the hands of Lord Gwayne Hightower deteriorated the relationship between green and black.
Gwayne was executed for treason by Visenya and Aegon with the help of Otto and Larys Strong usurped the throne. The dance took hold and the War of the Heirs began with the death of Prince Lucerys Targaryen.
