After the fall of the Srivijaya. it was divided into the cities Chaiya, Thatong and Khirirat Nikhom. While Chaiya was administrated directly from the capital, Thatong and Khirirat were controlled by the Nakhon Si Thammarat kingdom. In 1899 they were merged into one province named Chaiya. In 1915 also the court of the Monthon Chumphon was moved to Bandon, which received its new name Surat Thani on July 29, 1915 during a visit of King Vajiravudh (Rama VI). The monthon was renamed to Surat accordingly. In 1926 it was abolished and incorporated into monthon Nakhon Si Thammarat. In 1933 the monthon was dissolved, so the province became the first level administrative subdivision.
