Yommarat (Thai: ยมราช) is a Thai noble title historically given to the minister of the Krom Mueang or Nakhonban, one of the four ministries under the chatusadom system, which was responsible for maintaining peace and order in the capital. Holders of the title were typically granted the high rank of phraya or chaophraya. The title "Yommarat" is derived from "Yamaraja," the name of the Hindu god of death, Yama, who is believed to govern the underworld. The term "Yommarat" is thus a reflection of the minister's role in overseeing law and order, often in a manner that could involve matters of life and death, similar to the figure of Yamaraja in traditional beliefs.
Known historical holders of the title include:
During the Ayutthaya period:
During the Thonburi period:
During the Rattanakosin period:
Following the death of Chaophraya Yommarat (Choei), the title was left vacant, as the government was undergoing structural reforms abolishing the chatusadom system. A committee of four officials was established to oversee its functions in the interim period, before a modern ministry was re-established, named Krasuang Nakhonban or the Ministry of Metropolitan Affairs, in 1892. Prince Nares Varariddhi was named the first minister. In 1907, he was succeeded by Phraya Sukhumnaiwinit, who was named Chaophraya Yommarat (Pan Sukhum) the following year. He was the last holder of the title; the ministry was subsumed into the Ministry of Interior in 1922.
