U Thong is an ancient city. Archaeologists found many pre-historic instruments and human skeletons in many parts of the district. It was one of the center cities of Dvaravati culture. Later, it also became the origin of Ayutthaya kingdom, as the first King of Ayutthaya Ramathibodi was prince of U Thong before.
U Thong district was created with the name Chorakhe Sam Phan in 1905. In 1940, the government moved the central of district from Ban Chorakhe Sam Phan to the area of the ancient city. At the same time, they also changed the district name to U Thong.[1]
The district is subdivided into 13 subdistricts (tambon), which are further subdivided into 151 villages (muban). There are two townships (thesaban tambon) in the district - U Thong and Sa Yai Som each cover parts of the same-named tambon.
