The Khmer kings
1. 802 is the date when the institution of the supreme Kher king was initiated. Kings bore the title of maharajadhiraja or maharajadhipati, 'supreme king of king'. When Angkorian inscriptions refer to earlier kings. they use the word kurung. a Khmer word which may be translated equally as kingdom or king.
2. Parentage is not mentioned when the relationship is very close. Khmer succession was largely matrilineal, but irregular successions were not unusual and the direct line was not necessarily the legitimate one due to the practice of polygamy.
3.the actual date on which a particular king died is never known with any precision. The dates given for the various reigns are approximate as we also do not known whether the accession date refers to when the monarch took power or tho the date of his consecration.
