History

The command of King Chulalongkorn formed the division in 1905 on the recommendation of the Prince Chirapravati Voradej, the director of operations of the Ministry of Defence. The Prince wanted to organize the Siamese army on European lines, comprising at least ten army divisions. By 1906, the 1st Division became fully recruited and garrisoned in Bangkok. In 1908, the army was once again reorganized, by this date the division was made up of five units. The 1st Division was then given the responsibility of protecting the king, his Grand Palace, the royal capital and the surrounding Menam basin.
In the early hours of 24 June 1932, a revolution broke out in Bangkok. The Khana Ratsadon staged a coup d'état to replace the absolute rule of King Prajadhipok with a constitutional monarchy. The conspirators began by arresting key military personnel in the capital, including the Commander of the 1st Infantry Division; Phraya Saena Sonogram at his private residence. A scuffle ensued and an unnamed Lieutenant shot and wounded the resisting commander. Sometime later, a Major Luang Kraichingrit of the King's Own Bodyguards ordered a company of troops towards the Makawan bridge to resist the coup; however, by that time the revolution was a fait accompli and the troops were ordered to return to their barracks. Other than this one incidence of violence, the revolution was carried out smoothly without further bloodshed. The King complied with the Khana Ratsadon's demands and Siam was granted its first Constitution in December of the same year. As a result of the coup, the new administration temporarily dissolved all formations above battalion level, including the 1st Infantry Division.
During the Franco-Thai War of 1940-1941, the division's former components incorporated the Burapha Army on the orders of Field Marshal Plaek Phibunsongkhram. The division took part in the army's objectives of retaking the French Indochinese provinces of Sisophon and Battambang. After this brief conflict, the Burapha Army formation disbanded and the 1st Infantry Division commenced in 1942.
In 1948, the division moved into a permanent headquarters next to the Suan Kularb Mansion of the Dusit Palace. In 1956, the Royal Thai Army reorganized and the 1st Infantry Division came under the command of the First Army Area. In 1958, the division, in full, took part in the Royal guards parade to celebrate the birthday of King Bhumibol Adulyadej. Since that year, the division have taken part in the organizing and performing of the ceremony until the present day. On 2 April 1973, Royal Command designated the 1st Infantry Division as a King's Guard unit and changed its name to '1st Division, King's Guard', the first of its kind.
On 1 October 2019, 1st Infantry Regiment and 11th Infantry Regiment was put under the command of the Royal Security Command.
