Baramaraja

Baramaraja (Thai: บรมราชา), of mixed Siamese Mon–Chinese heritage,^[b] became the ninth monarch of Xiān at Ayodhya in 1310 following the death of his elder brother, Dhammaraja.^[3] His reign, extending from 1310 to 1344,^[3] was characterized by the revival of expansionist military activity, in continuity with the policies of his father-in-law, Suvarnaraja. In 1313, only a few years after his accession, Xian launched a protracted two-year campaign of invasion against Champa. This enterprise ultimately proved unsuccessful, as Champa later received military support from the emperor of Đại Việt.^{[4][5]: 122–123}

Baromarāja was the second son of a Chinese princess who married a mixed Mon–Chinese Dharmatriloka, king of Si Satchanalai. His principal consort was Sunandhadevī, the younger daughter of the 7th Ayodhya monarch Suvarnaraja.^{[2]: 69–71} Upon his death in 1344, he was succeeded by his only son, Varashreṣṭhakumāra (วรเชษฐกุมาร), who ascended the throne as Uthong V or Ramathibodi I, subsequently becoming the first king of the Ayutthaya Kingdom in 1351.^[3]

During the reign of Baromaraja, tributary missions were dispatched to the Yuan dynasty in 1314, 1319, and 1323.^[6]: 39 Subsequent embassies were recorded under the designations Xiānluó hú (暹羅斛) and Xiānluó 暹羅), appellations that referred to the polity later identified as the Ayutthaya Kingdom.^[6]: 40 In the period between 1334 and 1336, during the invasion of Ai Lao (later known as Sip Song Chau Tai) by the Trần dynasty, Xiān, together with other regional polities, rendered tribute to Đại Việt, as recorded in the Khâm định Việt sử Thông giám cương mục.^[7] Trade relations with China, Kula, Vilanda, Japan, India, and others, were recorded.^[8]
