History

edit

Chai Badan was an ancient town in the Pa Sak River valley, controlled from Nakhon Ratchasima. In 1914 it was upgraded to be a district of Phetchabun province. In 1918 it was moved to be part of Saraburi province. Finally it became part of Lopburi province on 1 November 1941.[1]

In 1943 the district office was moved from Chai Badan Sub-district to Bua Chum Sub-district,[2] which was undone one year later.[3] In 1960 it was again moved to Bua Chum.[4] The area around the district office was made the new Sub-district Lam Narai in 1970.[5]

Geography

edit
