 Issue Date:



To commemorate the 50th Anniversary of the Royal Institute, which was initially established on 19 April 1926 AD (2469 BE) as the Royal Society of Siam, but that was dissolved and split into the Fine Arts Department and the Royal Institute, in Thai called Racha Bandit Tayasathaan (ราชบัณฑิตยสถาน), on 31 March 1933 AD (2476 BE). In 2015 AD, the name changed to the Royal Society, in Thai referred to as Racha Bandit Thayasapha (ราชบัณฑิตยสภา). Though 31 March 1933 AD is the official date on which the Royal Society of Siam was disbanded, the foundation of the Royal Institute of Thailand was not officially enacted until 24 April 1934. For this reason, this postage stamp was issued on 31 March, yet in the year 1984 AD (2527 BE).
