Jayavarman IV

Jeyavarman IV (Khmer: ជ័យវរ្ម័នទី៤) was an Angkorian king who ruled from 928 to 941 CE. Many early historians thought that he was a usurper. However, recent evidence shows that he had a legitimate claim to the throne.

He was the son of king Indravarman I's daughter, Mahendradevi, and was married to his aunt, a half-sister of king Yasovarman I. Because there were no clear rules of succession, his claim for the throne through a maternal line seemed to be valid. He contested the reigns of Yasovarman I's sons at Angkor since the death of their father. In 921 he set up his own capital at Koh Ker: an inscription dated 921 states, "Jayavarman IV left the city of Yashodharapura to reign at Chok Gargyar taking the Devaraja with him." The rivalry lasted from 921 until the death of Ishanavarman II in 928, after which Jayavarman IV reigned supreme.

Famous for its ancient ruins, Koh Ker can be reached more easily then in recent past thanks to a toll road. This old capital city of Jayavarman IV remained abandoned for over a thousand years before French scholars, like Louis Delaporte and Étienne Aymonier, had been visiting and studying at the end of 19th century. During his reign the capital city was known as Chok Gargyar (the Island of Glory) or Lingapura. There was a walled city of about 1200 m², but subsidiary temples are scattered on a surrounding area of 35 square kilometers. The main zone encompasses the Rahal baray (1,188 x 548 m) and Prasat Thom complex, with its seven-tiered pyramid 30 metres high. The summit of the temple housed a colossal linga, now disappeared, probably made of metal casing as high as almost 5 metres. Inscription K.187E designates the Old Khmer name for this linga as kamrateṅ jagat ta rājya, “the god who is the king”. "Jayavarman IV's inscriptions boasted that his constructions surpassed those of previous kings." A large number of the best and largest Angkorian sculptures were made during his reign, e.g. the Garuda standing in the entrance of National Museum of Cambodia. A royal highway lead to Beng Mealea at south and to Angkor at west.
