History
The Royal Guards were established by King Chulalongkorn (Rama V) of Siam in 1859, when he was still a young prince. Initially, the Royal Guards were servants with duties such as scaring crows, which led to commoners referring to them as the "Mahat Lek Lai Ka," roughly translated as "Scarecrow Corps."

When he succeeded his father in 1868, King Chulalongkorn took his Royal Guard and formed a 24-strong Royal Bodyguard, referred to as the "Thahan Song Lo" (Two-Dozen soldiers"). In 1870, the unit was upgraded into a full army regiment and was given the name the "King's Guard" and their duties included escorting the king while he travelled around the country. The king commanded the regiment himself until 1873, when he appointed Lieutenant General Chao Phraya Phasakornwongse as its first military commander.

The Royal Guards still exist down to the present and serve as protectors of the royal family of Thailand.

On 18 January 2019, the unit has renamed to 1st King's Own Bodyguard Regiment. Then, on 23 April 2019, The unit has renamed again to 1st Infantry Regiment, King's Close Bodyguard.
