Chulalongkorn

Chulalongkorn, posthumously honoured as King Chulalongkorn the Great, was the fifth king of Siam from the Chakri dynasty, titled Rama V. Chulalongkorn's reign from 1868 until his death in 1910 was characterised by the modernisation of Siam, governmental and social reforms, and territorial concessions to the British and French empires. As Siam was surrounded by European colonies, Chulalongkorn, through his policies and acts, ensured the independence of Siam.
