History

Prior to the creation of the ministry, much of the country's foreign relations were handled by the absolute monarchs of the day. During the Kingdom of Ayutthaya foreign relations were handled by the "Krom Phra Khlang" ( (or the Treasury Department). The head of the department was known as "Phra Khlang" ( and occasionally referred to as "Berguelang" or "Barcelon" by foreign authors. A notable Phra Khlang Kosathibodi during the reign of King Narai was Kosa Lek, who was the elder brother of the famous 17th-century Siamese ambassador to France Kosa Pan. Kosa Pan also became a Phra Khlang Kosathibodi upon the reign of Petracha. Soon after, a sub-department called "Kromma Tha" (, "Port Department") was created to deal with foreigners. During the Bangkok Period most of these features were retained. For instance, the Chau Phaya-Phraklang in his capacity as Minister of State on behalf of Jessadabodindra negotiated the Siamese–American Treaty of Amity and Commerce of 1833 with Edmund Roberts in his capacity as Minister of the United States on behalf of President Andrew Jackson. In 1840, King Mongkut, the next king, founded the Ministry of Foreign Affairs of the Kingdom of Siam, which was administered directly by the king. The responsibilities and roles of the old "Krom" were shifted to this ministry. Chao Phraya Bhanuwong became the first Foreign Minister of Siam in 1871, appointed by King Chulalongkorn. In 1881 Prince Devavongse Varoprakarn was appointed to replace him. Known today as the "father of Thai diplomacy" he reorganized and modernized the ministry to meet 19th century standards. The ministry was then permanently established at Saranrom Palace, east of the Grand Palace. The ministry was divided into seven divisions:
