do they ever get into the past of the series? because I'm a bit confused about how things went down
like, how did Robert (?) become King when Jamie killed the previous one? sounds like the previous bloodline of white haired people, and the mad king (?) were all butchered. And Robert was a soldier with Ned, and some Starks were killed by the mad King or something?
The spark of the war happened at a tourney when Rhaegar Targaryen, Dany and Visery's older brother, won the jousting tournament and gave the winner's rose to Lyanna Stark instead of his own wife. At the time Lyanna was betrothed to Robert Baratheon, and he was sitting in the audience.
Some time after that Lyanna disappeared from King's Landing, and word spread that Rhaegar had kidnapped her. When Brandon Stark, Ned's older brother, heard the news he rode to King's Landing with some men to demand his sister be returned. The Mad King arrested them all, then sent letters to the north demanding their fathers come to court and explain themselves. When they came, including Ned's father, they were tortured and killed, as were the sons. Afterwards the Mad King sent letters to the Erie demanding John Aryyn arrest Robert Baratheon and Ned Stark, and hand them over to King's Landing. Aryyn had fostered them both through childhood and refused, instead calling his banners. The Starks and Baratheons eventually called their own banners, and the civil war broke out.
The rebellion won and Robert, who was a distant cousin to the Targaryens, was proclaimed king.
edit: here's the history of it including battles, if you want. No spoilers for future books
