Siem Reap
The name "Siem Reap" can be translated to mean 'defeat of Siam' (siem in Khmer), and is commonly taken as a reference to an incident in the centuries-old conflict between the Siamese and Khmer kingdoms, although this is probably apocryphal. According to oral tradition, King Ang Chan (1516–1566) had named the town "Siem Reap" after he repulsed an army sent to invade Cambodia by the Thai king Maha Chakkraphat in 1549. Scholars such as Michael Vickery consider this derivation to be simply a modern folk etymology, and maintain that while the names Siem Reap and Chenla. the old Chinese name for Cambodia, may perhaps be related, the actual origin of the name is unknown.
