Sakdina
Sakdina was a system of social hierarchy in use from the Ayutthaya to early Rattanakosin periods of Thai history. It assigned a numerical rank to each person depending on their status, and served to determine their precedence in society, and especially among the nobility. The numbers represented the number of rai of land a person was entitled to own—sakdina literally translates as "field prestige"—although there is no evidence that it was employed literally. The Three Seals Law, for example, specifies a sakdina of 100,000 for the Maha Uparat, 10,000 for the Chao Phraya Chakri, 600 for learned Buddhist monks, 20 for commoners and 5 for slaves.
