Yommarat
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.
