Ingnyeong

Ingnyeong was an earlier name of the district later known as Yangyang on Korea's eastern coast. Its administrative standing changed repeatedly before and after the founding of Joseon. In 1397 the court promoted it because it was the home district of King Taejo's maternal family. The national reorganization of 1413 made it a protectorate, and in 1416 it received the name Yangyang.

Its rank remained vulnerable to political punishment. In 1618 events associated with a literati purge led to demotion to county status; its former standing was restored in 1623. A further demotion followed a rebellion in 1627, with restoration in 1637. These changes affected an established local administration rather than creating a new settlement each time. The early Joseon establishment included a magistrate, an instructor and subordinate officials assigned to the government offices. The district's history therefore includes both the enduring work of local institutions and the court's use of administrative rank to reward or punish places.
