Goryeo military regime
The Goryeo military regime (Korean: 무신 정권; Hanja: 武臣政權) refers to a period in Goryeo history when military generals wielded considerable power, overshadowing royal authority and disrupting Goryeo's system of civilian supremacy and severe discrimination against military personnel. It spanned roughly 100 years from a coup d'état in 1170 to the Sambyeolcho Rebellion of 1270.
