The branch that Yi Ha-eung's family belonged to was an obscure line of descendants of the Yi clan, which survived the often deadly political intrigue that frequently embroiled the Joseon court by forming no affiliation with any factions. Yi Ha-eung himself was ineligible for the throne due to a law that dictated that any possible heir had to be part of the generation after the most recent incumbent of the throne, but his second son Yi Myeongbok was a possible successor to the throne.
