Administrative
reform of 1892[edit]
At the end of the 19th century King Chulalongkorn reformed the central government drastically. In 1892 the ministry, which previously had many overlapping responsibilities, was reorganized with clear areas as in western administrations. Prince Damrong Rajanubhab became minister of the Ministry of the North (Mahatthai), originally responsible for the northern administration. When the Ministry of the South (Kalahom) was dissolved in 1894, Prince Damrong became Minister of the Interior, responsible for the provincial administration of the whole country.
