Thailand observes Chulalongkorn Memorial Day on 23 October each year. The national public holiday commemorates King Chulalongkorn, also known as King Rama V, who died on 23 October 1910.
Known in Thai as Wan Piyamaharat, the day recognises one of Thailand’s most respected monarchs and his role in the country’s modernisation.
Why King Chulalongkorn Is Remembered
King Chulalongkorn ruled Siam, now Thailand, from 1868 until 1910. His reign brought significant changes to the country’s government, legal system, education, public administration and infrastructure.
He is particularly remembered for overseeing the gradual abolition of slavery and corvée labour. His government also expanded schools, introduced administrative reforms and developed railways, postal services and telegraph networks.
King Chulalongkorn maintained diplomatic relationships with international powers while working to protect Siam’s independence during a period of European colonial expansion in Southeast Asia. These achievements earned him the title “The Great Beloved King”.
How Chulalongkorn Memorial Day Is Observed
Commemorative ceremonies are held across Thailand, with government representatives, public organisations and community groups laying wreaths and floral tributes at statues and portraits of King Chulalongkorn.
The country’s principal ceremony traditionally takes place at the equestrian statue of King Chulalongkorn in Bangkok’s Royal Plaza. Provincial and local authorities may organise their own ceremonies at government buildings, monuments or other civic locations.
Visitors in Chiang Mai may see official commemorations or floral tributes during the day. These are respectful occasions rather than festivals, and local ceremony details can vary from year to year.
