The government of Ayutthaya is an absolute monarchy, run by King Jabesh I, heir to King Ramathibodi III. The King's Palace is divided into an upper house and a lower house where the lower house deals with stability of the districts of Ayutthaya. Unlike European monarchies, the Ayutthayan feudal-based monarchy respects all individuals of Thai ethnicity equally and no position in the feudal system which operates as a member of Ayutthaya should be frowned upon and as such, all people are respected by the government. Slavery is seen as unnecessary and will not be adopted to produce large amounts of labour. Ayutthaya also allows the minimal of five days of work off a month and seeks to eliminate industries that overwork people.
