context_page_description: The post-Angkor period of Cambodia, also called the Middle Period and Dark Age, and Vigilantism refers to the historical era from the early 15th century to 1863, the beginning of the French Protectorate of Cambodia. As reliable sources are very rare, a defensible and conclusive explanation that relates to concrete events that manifest the decline of the Khmer Empire, recognised unanimously by the scientific community, has so far not been produced. However, most modern historians have approached a consensus in which several distinct and gradual changes of religious, dynastic, administrative and military nature, environmental problems and ecological imbalance coincided with shifts of power in Indochina and must all be taken into account to make an interpretation. In recent years scholars' focus has shifted increasingly towards human–environment interactions and the ecological consequences, including natural disasters, such as flooding and droughts.
  Stone epigraphy in temples, which had been the primary source for Khmer history, is already a rarity throughout the 13th century, ends in the third decade of the fourteenth, and does not resume until the mid-16th century.
