Uiryeong County has a population of 27,550 and is one of the least populated counties in South Korea. No presence of Neolithic artefacts have been confirmed, however Bronze Age artefacts such as tombstones have been found in the region. The region is thought to have been in the domain of Aragaya and the Bisabeol region, during the Three Kingdoms period in Korea, and is thought to have been under the influence of the Kingdom of Silla, after the province of Haju was installed in the region of Changnyeong in 555. The region was also known as Jangham prefecture under Silla, but the prefecture's name was changed to Uiryeong in 757, and became kind of a subprefecture under Haman prefecture. The Sinban region, then also known as Sinui prefecture, Juo township or Cheoncheon prefecture, became the subprefecture in the domains of Gangyang County with the new name "Uisang prefecture".
