The others are K.133 [I], a \"chief ship pilot\", mahanauvaha, in K.140 [K] a \"master of all elephants,\" or \"vassal king\", samantagajapati; in K.765 [T] a mahanukrtavi-khyata, \"celebrated for his great following\"; in K725 three such titles or names of functions, samantanauvaha, \"chief of the naval forces\", mahasvaptai, \"great chief of horse\", sahasravargadhiptai, \"chief of a group of a thousand\"; in K726 yuddhapramukha, military officer; and the latest in date a certain mahavikrantakesari, a name meaning \"great bold lion\", probably indicating a military person, who is mentioned 4 times in K1029 [R].]'§REF§(Vickery 1998,  125)§REF§ 'Jayavarman I was the great-grandson of Ishanavarman. His inscriptions indicate the tightening of central power and control over a considerable area, the creation of new titles and admin- istrators, and the availability of an army, the means of defense and destruction. A text described how King Jayavarman’s commands were obeyed by “innumerable vassal kings.” Jayavarman also strengthened the legal code: “Those who levy an annual tax, those who seize carts, boats, slaves, cattle, buffaloes, those who contest the king’s orders, will be punished.” New titles were accorded highly ranked retainers who fulfilled important posts in government. One lineage held the priestly position of hotar. Another functionary was a samantagajapadi, chief of the royal elephants, and a military leader; the dhanyakarapati would have controlled the grain stores. The king also appointed officials known as a mratan and pon to a sabha, or council of state. Another inscription prescribes the quantities of salt to be distributed by barge to various foundations and prohibits any tax on the vessels going up- or downriver. Thus Jayavarman I intensified royal control over dependent fiefs begun by his great-grandfather, Ishanavarman. Thereafter this dynasty loses visibility, although the king’s daughter, Jayadevi, ruled from a center in the vicinity of ANGKOR.§REF§(Higham 2004,  75)§REF§ 'Their contents inform us on two vital issues. The first is the use of official titles, such as President of the Royal Court, which was located at a centre called Purandarapura. Another prescribed punishment for those who disobey a royal order. Two brothers of high social standing were appointed to a variety of posts: officer of the royal guard, chief of rowers, military chief, and governor of Dhruvapura. Another highly-ranked courtier became chief of elephants, reminding us of the traditional role of elephants in warfare. A further text mentions a chief of the royal grain store. These high officials were rewarded with honorific symbols, such as a parasol embellished with gold. The trends already evident under Ishanavarman were greatly strengthened under his great grandson: with Jayavarman I, we can identify the establishment of a state. It was, however, ephemeral. Only one inscription of his daughter Jayadevi survives. Thereafter, the dynasty disappears from the historic record.'§REF§(Higham 2014b,  294)§REF§"
