Meanwhile, an aristocratic Buddhist monk leader, Gung Ye, declared a new Goguryeo state in the north in 901 CE, known as Later Goguryeo (Hugoguryo). Gung Ye was either the illegitimate son of Gyeongmun of Silla or Heonan of Silla depending on the account. He, too, had formed an alliance with Yanggil but proved rather more ruthless and killed the bandit, clearing the way to declare himself king in his own right. His capital was first at Songak (Gaesong) and then Cheorwon. He also twice changed the name of his kingdom – to Majin in 904 CE and Taebong in 911 CE – illustrative of his unstable character. One thing that never changed was Gung's hatred of Silla and his insistence that his subjects always refer to it as the 'nation of the damned.'
