( 1292-1309) and that of his successer, Jayanagara ( 1309-28) were full of
disturbances, and Java did not interfere in the affairs of Sri Vijaya.
However, embassies to China were sent in 1297, 1298, 1300 and 1308
A.D.
1293 A.D. The Javanese forces sent to occupy Malayu (Central
Sumatra) returned home. They took back with them two princesses,
Dara Jingga and Dara Petak the younger of whom is said to have married
the new king Krtarasa, and was known as Indresvari; while the elder,
Dara Jingga, is said to have become the mother of a future king of
Malayu.
1295 A.D. Kublai Khan sent a messenger to the king of Sien to say
that "you should keep to the word you have given and stop killing the
people of Malaiur". Sien should mean Sukhothai, and the king was Ram
Kamhaeng. Malaiur was Nakorn and not Malayu in Sumatra (see under
Marco Polo 1292 (a) above). It bears repeating that the Thai were
landlubbers and there is no record of their interfering in the affairs of
Sumatra.
There seems to be a great deal of confusion over the Chinese
toponyms of the states in the Central Plain of Siam, so I will confound
the whole situation just a wee bit further. There were two states roughly
divided by the Menam Chao Phya (river). The Chinese called the eastern
state Lokok (Marco Polo's Locac). This was Lopburi or Lawo-kok if I
may call it that because Lawo was the old name of Lopburi. When the
capital moved to Ayodhiaj Ayudhia the name Lokok was still used.
The state on the western side was called Siemkok (Siam-kok). Early
in the Christian Era, Ptolemy called this place Samarade (an inland town),
which is tbe same as Samrattha, a name I understand the Indians still use
to call Siam. It would seem that when the Thai came from the north
into the Central Plain, they took over a Siam that had been occupied by
other races such as the Mons, and possibly some other races before the
Mons. The main locations of Sien were Nakorn or Lakorn Cbaisri (present
Nakorn Patbom) which the Chinese called Lang-ya-shu; Supanburi
