Po Tisuntiraidapuran (?–1793) was a ruler of the Panduranga Kingdom of Champa (in Vietnamese, Thuân Thành) who ruled from 1780 to 1781 or 1782, and again from 1786 to 1793. His Vietnamese name was Nguyá» n VÃÂn Tá (é®æÂÂä½Â). He ruled in a difficult time, when the Tây Sán wars ravaged Vietnam. He generally supported the Tây Sán rebels against Nguyá» n ÃÂnh and was later executed by ÃÂnh when he proved victorious.
The Cham chronicles say that Po Tisuntiraidapuran was not (closely) related to his immediate predecessors. He was however a descendant of the early 18th century king Po Saktiraydapatih. He was born in a Year of the Dog (1742, 1754, etc.) and was originally a Cham lord under king Po Tisuntiraydapaghoh, who followed Vietnamese forces in southern Vietnam (whether Tây Sán or Nguyá» n is not specified). Allegedly, he killed some envoys of the Tây Sán ruler Nguyá» n Nhạc. The blame for the murders was put on Po Tisuntiraydapaghoh who was deposed and executed by the Tây Sán. Instead, Po Tisuntiraidapuran was appointed ruler of Champa with the title cai cá by "the Vietnamese king" (either Nguyá» n Nhạc or Nguyá» n ÃÂnh). His position was extremely tenuous, since Champa was a badly afflicted victim of the Vietnamese civil war since 1771. The fate of the small polity was entirely dependent on the outcome of the strife between the Tây Sán dynasty and the Nguyá» n lords.
Po Tisuntiraidapuran is said by the Cham chronicles to have ruled for one year and then forced to flee in the year of the Buffalo (1781). It is not clear where he fled. Historical tradition explains that the old king left a son in Cambodia, Po Krei Brei, who managed to prove his father's innocence. Po Tisuntiraidapuram, however, found support from the mother of the Vietnamese ruler, and escaped punishment. However, the chronology of events is not clear: Vietnamese chronicles say that the Tây Sán rebels invaded Bình ThuáºÂn in 1782 and were approached by Po Tisuntiraidapuran who submitted to them. He offered the royal seals to the Tây Sán leaders and was later on regarded as a traitor by Nguyá» n ÃÂnh. Inconsistent with this, the Cham chronicles speak of an interregnum for two years (1781-1783). This was followed by the brief reign of Po Krei Brei (1783-1786) who was appointed by Nguyá» n Nhạc but fled from Champa after three years. Now Po Tisuntiraidapuran was appointed ruler for the second time by Nguyá» n Nhạc, in the Year of the Horse (1786).
According to the Cham chronicles, Po Tisuntiraidapuran managed to retain power over Champa for eight years. At the beginning, his rule was popular since forced deliveries of elephant tusks, rhinoceros horn, and wood were abolished. As he mainly thought of his own dignity and spent much time on hunting, he nevertheless soon fell in popular esteem. Moreover, Vietnamese sources suggest a more complicated political situation; they say that Nguyá» n ÃÂnh fought the Tây Sán in the region in 1790, and appointed Po Krei Brei (Nguyá» n VÃÂn Chiêu) as governor of the Cham lands with the title Khâm Sai Chuá»Âng Cá. At the same time another Cham notable, Po Ladhuanpuguh (Nguyá» n VÃÂn Hào) was instrumental in conquering the Phanri region for Nguyá» n ÃÂnh and was made governor of three highland districts. There were therefore a few competing Cham rulers at the time.
In 1793, Phanri was definitely secured by the army of Nguyá» n ÃÂnh. Po Tisuntiraidapuran was defeated and forced to flee with the Tây Sán general Hô Van Thá»±. He took shelter in the highland districts but was captured by the forces loyal to Nguyá» n ÃÂnh and Po Ladhuanpuguh. He was executed in ÃÂá»Âng Nai (adjacent to Gia ÃÂá»Ânh, present-day Ho Chi Minh City) "for his crimes". Since then, Champa rulers did not use the title ThuáºÂn Thành trấn phiên vðáng (é ÂÃ¥ÂÂé®è©çÂÂ, "Vassal king of ThuáºÂn Thành trấn"); Champa was regarded as a chiefdom under Vietnamese thá» ty system.
