Pú jiā yuè mó

Pú Jiā Yuè Mó (Chinese: 蒲伽越摩) is recorded in the Chinese leishu Cefu Yuangui and New Book of Tang as a Siamese ruler who governed the polity identified as Gē Luó Shě Fēn (哥罗舍分) during the late 8th to early 9th centuries,^[1]: 23 succeeding Pra Poat honne Sourittep pennaratui sonanne bopitra. His reign is believed to have been marked by a territorial expansion covering Si Thep, associated with Qiān Zhī Fú, and the western Menam valleys, a region that had earlier been under Dvaravati control. This expansion appears to have constrained Dvaravati political power to the eastern Chao Phraya basin, where authority was concentrated at Lavapura of Lavo.^[a] The designation Gē Luó Shě Fēn is generally regarded as a corrupted transcription of Jiā Luó Shě Fú (迦逻舍佛), which has been interpreted as Canasapura, a polity centered at Si Thep, with Mueang Sema functioning as an important eastern center.^{[2]: 38–9} His Chinese regnal name has not yet been systematically transliterated into local vernaculars.

The kingdom under his rule is thought to have engaged in commercial interactions with Srivijaya to the south. According to later accounts, a Siamese naval force led by Passara, identified as the son of the Siamese king, is said to have sailed toward Macassar on Sulawesi. The expedition reportedly failed after encountering a storm near Bali, and the fleet subsequently diverted to Java, where they founded the city of Passaraan around 800 CE.^[3]: xvi During this period, Gē Luó Shě Fēn is reported to have maintained a military force of approximately 20,000 elite soldiers, reflecting a considerable degree of political organization and regional power. The polity is also described as sustaining close relations with Xiū Luó Fēn, which is reported to have commanded a force of 30,000 personnel, and with Gān Bì, whose military strength is said to have comprised only 5,000 troops, suggesting the existence of wider networks of alliance or tributary interaction in the region.^[4] These three brother kingdoms are recorded as having dispatched embassies to the Chinese court during the Tang period.^[4]

Pú Jiā Yuè Mó was probably succeeded by Sikaraj, a figure described in tradition as a mythical king of Kamalanka at Nakhon Pathom, which came to be referred to as Sri Vijaya in local legends, reflecting the cultural and commercial influence of the Srivijaya empire through maritime trade networks.^{[5]: 14–5}
