betrayed Gyeon Hwon. Later Goguryeo Taebong (901–918), also known as Majin or Later Goguryeo, was established by Gung-ye, an outcast prince of Silla. Gung-Ye joined General Yang-Gil's rebellion, and rose through the ranks. He eventually assassinated Yang-Gil and established a new kingdom, naming it Later Goguryeo. Gung-Ye turned out to be a tyrant, and was overthrown by his generals, opening the way for General Wang Geon, who established Goryeo. Goryeo dynasty Goryeo (918–1392) was ruled by the Wang Dynasty. The first ruler had the temple name Taejo, which means "great progenitor", and was applied to the first kings of both Goryeo and Joseon, as they were also the founders of the Wang and Yi Dynasties respectively. Starting with Gwangjong, rulers of Goryeo styled themselves emperors, with the first three rulers elevated to that title posthumously. With the Mongol conquest, however, the title of the ruler was demoted to a king, or "Wang." The next twenty-three kings (until Wonjong) are also referred to by their temple names, ending in jong. Beginning with Chungnyeol (the twenty-fifth king), all the remaining kings of Goryeo had the title Wang ("King") as part of their temple names. Era names are in bracket where available. Joseon dynasty Joseon (1392–1910) followed Goryeo. In 1897, when Joseon became the Korean Empire, some of the Joseon kings were posthumously raised to the rank of emperors. Joseon monarchs had temple names ending in jo or jong. Jo was given to the first kings/emperors of new lines within the dynasty, with the first king/emperor having the special name (Taejo), which means "great progenitor" (see also Goryeo). Jong was given to all other kings/emperors. Two kings, Yeonsangun and Gwanghaegun, were not given temple names after their reigns ended. Each monarch had a posthumous name that included either the title Wang ("King"), Hwangje ("Emperor"), Daewang ("King X the Great"), or Daeje ("Emperor X the Great"). For the sake of consistency, the title "King/Emperor" has been added to each monarch's temple name in the list below. * see Korean Empire section Korean Empire In 1897, King Gojong proclaimed Joseon to be the Korean Empire, which lasted until 1910. Technically, the emperors can be referred to by their era names rather than their temple names, but the latter are commonly used.
