H.R.H. Mahisara is regarded as the father of Thai banks. The son of King Mongkut (Rama IV) and his queen, Huang, H.R.H. Prince Mahisara was born on Monday, the 13th night of the waxing moon, in the 3rd month of 1865.
In his youth, he served as a royal guard before moving to the Office of His Majesty’s Principal Private Secretary.
His talents were soon recognized and he was promoted to successively higher offices, ultimately becoming Minister of the Royal Household.
His great intelligence and capability led to his being raised to the rank of Royal Prince in 1895, when he was only 30 years old. His name was recorded in the gilded royal records as “Phrachao Nongyather Prince Mahisara Musikkanam, with a land status of 150,000” i.e. holding 150,000 rai (0.4 acres) of land bestowed by the king. He was also made a Colonel of the Royal Guard. After his promotion, he was elevated to serve as Minister of the Royal Treasury, the equivalent of Finance Minister. In 1897, he was selected to accompany King Chulalongkorn on the first royal state visit to Europe by a Siamese monarch.
