He was the eldest son of the 10th king Bunseo, who was assassinated in 304.
[1] The Samguk sagi records that "he was naturally hard and brace, and skilled with horse and bow.
When Bunseo died, Gye was too young to succeed him, so Biryu (younger brother of the 7th king Saban) succeeded him, dying in the 41st year of his own reign.
[2][3] His rule indicated the continued the rivalry between two royal lines, that of the 5th king Chogo and that of the 8th king Goi, from whom Gye descended.
The Goi line ended with Gye's 2-year reign, as he was succeeded by Biryu's son Geunchogo.
