Of all the countries in the region, Cambodia is the one with the most painful recent history. When Pol Pot took control and began his shocking reign of terror, the country lost so much, so quickly. The Khmer Rouge took control of the country in April 1975 and what followed was genocide of almost previously un-witnessed proportions. Know as Year Zero, the Khmer Rouge began the systematic destruction of all culture and traditions. Teachers, musicians, intellectuals and artists were singled out and summarily executed. In the following three years possibly as many as three million people were executed. Up to 20,000 mass graves were discovered in the Killing Fields to the north of Phnom Penh.
The magnificent Angkor Temples are of course a huge bonus for any country trying to develop tourism. Once seen never forgotten they are the most important Buddhist temple site in the world and the largest temple site of any kind anywhere. However, Cambodia is much more than that. Phnom Penh, Siem Reap, Luang Prabang and many more destinations are now pulling huge numbers of tourists in.
