5. Influenced by the Meiji restoration in Japan, and following in his father King Mongkut's footsteps in continuing economic and political reforms in Thailand, which Thai king abolished slavery and established a modern civil service in Thailand?
From Quiz Modern Thai History
Answer:
Chulalongkorn
King Chulalongkorn (Rama V), the 5th king of the Chakri dynasty, also attempted to modernize Thailand's legal and administrative structures. In order to allieve the ethnic Chinese 'problem', he forced ethnic Chinese to take Thai family names. His reign, which lasted from 1868 to 1910, saw Thailand become an entirely different, and modern, country.
