Gapyeong

Gapyeong lay on the boundary between two of Joseon Korea's provinces. In 1413 it was transferred from Gangwon to Gyeonggi, and a hyeongam, or local magistrate, was appointed. Its rank changed repeatedly during the dynasty: the hyeon was raised to a gun in 1507, reduced to a hyeon in 1697, and restored to gun status in 1707.

The name itself was older than Joseon. It had been adopted in 757 under Unified Silla, and in 1018 the district became subordinate to Chunju, today's Chuncheon. The early Joseon transfer therefore redirected an established district from the provincial system centred on Chuncheon into Gyeonggi, the province surrounding the royal capital.
