Wang Thong was established in 1895 as Nakhon Pa Mak District, named after the central
tambon, the district office being located in
Ban Sam Ruen. However, the original location was difficult to reach and also flooded every year, and the district office was moved to the east side of the Wang Thong River, where the Wang Thong Municipal Market now stands. In 1928 the government created
Bang Krathum district, and tambons Phai Lom, Noen Kum, and Nakhon Pa Mak were assigned to it. Tambons Kaeng Sopha and Ban Klang of
Nakhon Thai district were reassigned to Wang Thong. When the buildings on the east bank of
Wang Thong River were washed away by a flood, the district office relocated to its present site. In 1931 the district name was changed to Pa Mak, finally designated as Wang Thong in 1939. ==Geography==
