Dusit Thani
Bangkok, Thailand · built 1918
Dusit Thani was a miniature city and micronation project created by King Vajiravudh (Rama VI) of Siam (Thailand) in Dusit Palace (later moved to Phaya Thai) in the 1910s–1920s. The project explored aspects of democracy, as members of the court were to be "citizens" owning property in the model city. Elections were held, a constitution written, and two newspapers regularly published for the fictional country. Although critics have dismissed the project as nothing more than the king playing with dollhouses, others regard it as the first trial of a constitutional government in Thailand.
