English: # Ratchaphongsawadan Khamen ("Royal Khmer Chronicle"), aka Phongsawadan Khamen ("Khmer Chronicle") and Phongsawadan Khamen Choso Phan Song Roi Sipchet ("Khmer Chronicle, 1217 LE"), is a Thai translation of a royal chronicle of Cambodia originally written in Khmer. The original Khmer manuscript was presented by King Duong of Cambodia to King Mongkut of Siam in an unknown year. King Mongkut had it translated into Thai by a committee led by a Siamese nobleman titled Khun Sunthonwohan, assistant chief of the Scribal Department. The translation was done in the Year of the Rabbit, 1217 LE (2398 BE, 1855/56 CE). King Chulalongkorn of Siam had the Royal Printer publish the translation for the first time as this book. The translation was printed for the second time by Watcharin Borisat Printer in 2445 BE (1902/03 CE) and was printed for the third time by the Thai Printer in 2457 BE (1914/15 CE) as part of the Collection of Historical Archives: Volume 1.
