Early Joseon Period


The Early Joseon Period (1392 - c. 1550 CE) in Korea was bookended by internal power struggles but witnessed major scientific and societal advances and prosperity. The Joseon (Choson) Dynasty ruled Korea from 1392 CE to 1897 CE, and scholars typically break this 500-year dynasty into three periods: the Early Joseon, the Middle Joseon, and the Late Joseon periods. This period in Korean history saw great strides in science, culture, literature, and education; long periods of peace peppered with invasions from neighboring China and Japan; and isolationist policies from the 18th through the 19th century CE.
