The original name of Pathum Thani is Muang Sam Khok which was founded during the Ayutthaya era and was the settlement of Mon People migrating from Motama. When King Rama II made a royal visit to Muang Sam Khok, a lot of the inhabitants of Sam Khok offered him lotus. Thus he then gave to Sam Khok the new name of Pathum Thani which means The City of lotus.
