The minor district (
king amphoe) was created on 1 April 1995, when the three
tambons Nong Hi, Sao Hae, and Duk Ueng were split off from
Phanom Phrai district. The Thai government on 15 May 2007, upgraded all 81 minor districts to full districts. With publication in the
Royal Gazette on 24 August, the upgrade became official. ==Administration==
