Why Did Bran Become King
Bran Stark was chosen as king because the lords and ladies of the Great Houses needed a new leader after Daenerys Targaryen's death. They debated candidates and ultimately voted for Bran, who presented himself as a ruler with a unique perspective on history and impartiality.
What Made Bran a Candidate
Bran was the last known surviving son of Ned Stark. He had survived a fall, became a greenseer, and could access the collective memories of the world. His supporters argued that his knowledge made him a wise, detached choice who could guide the realm beyond the conflicts of the living families.
How Bran Was Chosen
The decision was made at a small council meeting in the Dragonpit, attended by key leaders including Sansa, Tyrion, and Jon Snow. Tyrion proposed an election rather than a conquest, and the assembled lords agreed to choose their ruler by vote, resulting in Bran's selection.
