TukuâÂÂaho was the 14th TuâÂÂI Kanokupolu of Tonga, reigning approximately from 1793 to 1799. He was considered the âÂÂstrong manâ of the Tupou family despite coming from a lower lineage, and he used his power to depose the 12th TuâÂÂI Kanokupolu, Tupoumoheofo, who was of the higher line. TukuâÂÂaho placed instilled his own father, Mumui, as the 13th TuâÂÂI Kanokupolu and then took the title for himself upon Mumui's death. TukuâÂÂaho reigned Tonga as a tyrant, for which he was assassinated by a team of high chiefs. His death sparked a civil war that lasted for nearly a half century.
Around the year 1792, when MukuihaâÂÂameâÂÂa vacated his title of TuâÂÂi Kanokupolu, the recently deceased TuâÂÂi Tonga's high ranking wife Tupoumoheofo declared herself the replacement. Historians debate the appropriateness of her action as a female, but the immediate result was to incense TukuâÂÂaho, who hoped for and expected the title to pass on to his father. From âÂÂEua where he was now governor, TukuâÂÂaho began publicly denouncing Tupoumoheofo. He further instigated conflict by seizing some of her estates.
Tupoumoheofo would not step down. Mumui, TukuâÂÂaho, and Tupoumoheofo all shared ancestry through MaâÂÂafuâÂÂotuâÂÂitonga, the 6th TuâÂÂI Kanokupolu, but TupoumoheofoâÂÂs branch was of higher rank, which helped give her support among many of the Tongatapu chiefs.
With Tupoumoheofo in power for less than a full year, probably around the year 1793, TukuâÂÂaho attacked her supporters with an army, chasing her into the protection of the powerful chiefs of Hihifo. In the face of overwhelming force, the chiefs negotiated her exile to HaâÂÂapai, leaving TukuâÂÂaho to implant Mumui as the 13 TuâÂÂI Kanokupolu and MaâÂÂulupekotofa as TuâÂÂI Tonga.
The exiled Tupoumoheofo made one last attempt to reclaim her title by raising an army and attacking Tongatapu, but she was repelled and chased back to Kauvai Island in northern HaâÂÂapai, where her army was slaughtered. Tupoumoheofo survived and returned to VavaâÂÂu. She made no more attempts to regain power.
Mumui helped bring stability after a brief period of war. By 1795 the three main chiefly titles of TuâÂÂi Kanokupolu, TuâÂÂi HaâÂÂatakalaua, and TuâÂÂi Tonga had been restored to âÂÂmen with solid traditional claims of descent and fitness. Just before he died, he tried maintaining stability by trying to pass his TuâÂÂI Kanokupolu title on to MulikihameâÂÂa, who was the next most âÂÂpremierâ chief on Tongatapu and came from a more superior branch of the family lineage. He had also previously held the title as the 11th TuâÂÂi Kanokupolu before he was likely forced to resign in 1790 or 1791. The choice of MulikihameâÂÂa was in line with the Tongan tradition of adelphic succession and was unlikely to cause any political problems. Some surmise that Mumui passed over his own son because he anticipated TukuâÂÂaho's "excesses and cruelties" of power.
Though Mumui could strongly suggest his own replacement, the decision of the next TuâÂÂi Kanokupolu was made by election of the chiefs of Ngata in Hihigo. TukuâÂÂafo felt indignant by being passed over for the title, having most likely placed his father as TuâÂÂI Kanokupolu to improve the power of their lineage and receive the title in the future. As the âÂÂstrong manâ of the Tupou family, TukuâÂÂaho convinced the chiefs to elect him as the 14th TuâÂÂi Kanokupolu. The action steered power towards a lesser lineage and angered many chiefs.
TukuâÂÂaho behaved as a tyrant. He waged war against HaâÂÂapai and VavaâÂÂu, spreading âÂÂhavocâ and âÂÂfearâ throughout Tonga. A European eyewitness described TukuâÂÂaho tying enemies to trees and burning them alive. Other missionaries said he cut off the hand of a man who had committed a misdemeanor. Another was âÂÂbound with stretched arms and two women were made to put burning torches under his armpits. He had the left arm of twelve of his cooks amputated not to punish any crime but as a âÂÂpersonal reminder to make clear that they were his.âÂÂ. One woman was sawed in half while still alive. William Mariner, a British sailor stranded in Tonga from 1806 to 1810 described TukuâÂÂaho's reputation as âÂÂof a vindictive and cruel turn of mind, taking every opportunity to exert his authority; and frequently in a manner not only cruel but wantonâÂÂ, though it must be said that Mariner's host was TukuâÂÂaho's enemy, Finau Ulukalala II.
TukuâÂÂaho earned many enemies due to his tyranny and ignorance of traditional succession. The April 1799 ritual reburial of 18th TuâÂÂi HaâÂÂatakalaua, Toafunaki, brought chiefs from many Tongan islands, and a group of them decided to assassinate TukuâÂÂaho. They were led by Tupouniua who felt particularly oppressed by TukuâÂÂaho's reign. He was joined by many power men such as Finau âÂÂUlukalala II, MulikihaâÂÂameâÂÂa, and Fatafehi Fuanunuiava. Finau âÂÂUlukalala was avenging his father, Finau âÂÂUlukalala I, who was not given the governorship of VavâÂÂu by TukuâÂÂaho that he thought he deserved. MulikihaâÂÂameâÂÂa was still angry at not receiving the TuâÂÂi Kanokupolu title years earlier. Fatafehi Fuanunuiava, the son of the 36thTuâÂÂI Tonga Paulaho, also felt eligible for the TuâÂÂi Kanokupolu title.
William Mariner describes the assassination in detail:
<blockquote>âÂÂAbout midnight they again repaired to [TukuâÂÂahoâÂÂs] house with [the plotters], whom they placed around it as watchful guards, ready to despatch all who might attempt to escape from the place. Of these Finow [Finau] took the command, whilst Toobo Nuha [Tupouniua] entered, armed with his axe, and burning with desire of revenge. As he passed along, on either hand lay the wives and favourite mistresses of the king...He sought the mat of his destined victim, where he lay buried in the profoundest sleep. He stood over him for a short moment, but willing that he should know from whome he received his death, he struck him with his hand upon the face. Togoo Ahoo [TukuâÂÂaho] started up, -âÂÂTis I, Toobo Nuha that strike!â and a tremendous blow felled him, never to rise again.âÂÂ</blockquote>
The solidarity of the conspirators did not last long. Contests for power devolved into chaos in Tongatapu with Finau âÂÂUlukalala becoming ruling warlord over HaâÂÂapai and Tupouniua his deputy in VavaâÂÂu. Thus began the civil wars that wouldn't end until the 1845 unification of Tonga under TaufaâÂÂahau (a grandson of TukuâÂÂaho).
