During the Rattanakosin Period, the kingdom's administration was similar to that of the Ayutthaya Period. There were two chief ministers (: the first running military affairs or "samuhakalahom  (, and the second Samuhanayok" ( for civilian affairs. The civilian ministry was divided further into four "kroms" (, headed by a "senabodi" ( or 'minister'. This type of administration was called the "Chatusadom" ( : Rama V reforms. King Chulalongkorn (Rama V), who had received a European education and traveled widely, reformed the administration of the state. In 1875, he issued a royal decree to bring about this reform, dividing and creating many departments, and thereby preventing the archaic system from collapsing. The administrative reforms of Chulalongkorn created six ministries (, each headed by a minister of state or (, ): A further four were soon added: By  1900 the entire structure was formed. The ten ministries became the center of Siamese government and rule. After the 1932 Revolution, most of the ministries were retained by the Khana Ratsadon, however from then on the ministers were chosen by the prime minister and not the king.
