Korean era names were titles adopted in historical Korea for the purpose of year identification and numbering. Era names were used during the period of Silla, Goguryeo, Balhae, Taebong, Goryeo, Joseon, and the Korean Empire. Various Korean regimes officially adopted the era names of Chinese dynasties.
Era names originated in 140 BCE in China, during the reign of the Emperor Wu of Han. Since the middle of the 6th century CE, various Korean regimes started to use era names.
