Establishment of Baratheon Dynasty

Following the conclusion of the rebellion, Robert I Baratheon was successfully installed as the new Lord of the Seven Kingdoms. Robert named his foster father, Jon Arryn, as his Hand of the King, and he named his middle brother, Stannis, as Lord of Dragonstone.

Robert had no wish to marry following the death of his betrothed, Lyanna Stark, but Jon convinced him otherwise by informing Robert that the realm was in need of an heir. Jon suggested Lord Tywin Lannister's daughter, Cersei, as the marriage would ensure Tywin's support, should Viserys Targaryen ever attempt to win his throne back. Robert and Cersei married in 284 AC, Maester Yandel described the marriage as Robert's "first act" as king.
