# Ratchasakun

Ratchasakun (Thai: ราชสกุล) refers to the surnames indicating royal descent from a Thai monarch of the Chakri Dynasty, first established in 1912 after King Rama VI enacted a series of laws granting surnames to the Thai people, with the laws expressly stating that all Thai citizens must have a "surname" indicating who they are related to, or whom they are descended from, with those who are direct members of the royal bloodlines to be called ratchasakun, those who have marital ties to the royal family to be referred to as ratchanikun (ราชนิกุล), and those descended from a Chakri Front Palace to be called bowon ratchasakun (บวรราชสกุล).

## Ratchatrakul

Ratchatrakul (ราชตระกูล) are the royal houses which are descended directly from the siblings of King Rama I. This refers to those not of the immediate royal family, meaning those of the rank of Serene Highness (Mom Chao) or below. Untitled ratchasakun or spouses of ratchasakun shall take the suffix of na Ayudhya (modern alternatives: Na Ayutthaya) behind the surname as well, to signify royal heritage.
