Background and detail

Background. King Mongkut, who reigned from 1851, died on 1 October 1868. His son, Chulalongkorn, ascended the throne in 1868. The Grand Palace in Bangkok, the official residence of Siamese kings since 1782, was the setting for these events. The term 'King of Siam' was formally adopted during Mongkut's reign, establishing the diplomatic context for Chulalongkorn's succession.

Transition of Rule. Chulalongkorn's accession followed the death of King Mongkut on 1 October 1868. The legacy date of 1 October 1868 corresponds to Mongkut's death, not to a separately sourced accession or coronation date for Chulalongkorn; the supplied passages state only that his reign began in 1868. The Grand Palace remained the official residence of the Kings of Siam during this period.

Grand Palace Context. The Grand Palace, located in the heart of Bangkok, has been the official residence of the Kings of Siam since 1782. When King Rama V (Chulalongkorn) ascended the throne in 1868, he decided to build a new group of grander throne halls to replace the old structures at the palace complex.
