Tuku'aho
Tuku’aho was the 14th Tu’i Kanokupolu of Tonga, ruling around 1793 to 1799. Though he came from a lesser branch of the Tupou family, he was the strongman of the group and used his power to push out Tupoumoheofo, the 12th Tu’i Kanokupolu who came from a higher line. Tuku’aho put his father Mumui in as the 13th Tu’i Kanokupolu and then took the title for himself after Mumui died. He ruled Tonga as a harsh leader, and his cruelty made many enemies. He was eventually assassinated by a group of high chiefs, and his death sparked a civil war that lasted for about fifty years.
Background before the murder
Around 1792 the recently deceased Tu’i Tonga’s wife Tupoumoheofo declared herself the replacement for the throne. Some historians question whether a woman should hold the title, but the immediate result was to anger Tuku’aho. He hoped the title would pass to his father Mumui. From his base on ‘Eua, Tuku’aho spoke out against Tupoumoheofo and even seized some of her lands. Tupoumoheofo’s supporters were strong on Tongatapu, especially among Ha’apai chiefs, and Tupoumoheofo kept power for a short time.
The fall of Tupoumoheofo and rise of Tuku’aho
Tuku’aho’s forces attacked Tupoumoheofo’s supporters and chased her to the protection of powerful chiefs in Ha’apai. The chiefs arranged her exile to Ha’apai, while Mumui was made the 13th Tu’i Kanokupolu and Ma’ulupekotofa was made Tu’i Tonga. Tupoumoheofo tried to reclaim the throne with an army from Kauvai in Ha’apai but was defeated. She survived and eventually returned to Vava’u, but she never regained power. Mumui helped bring a period of stability.
Later events and Tuku’aho’s rule
By about 1795 the three main titles—Tu’i Kanokupolu, Tu’i Ha’atakalaua, and Tu’i Tonga—were held by men with strong traditional claims. Before he died, Tuku’aho tried to pass his title to Mulikihame’a, a respected chief from Tongatapu who had previously held the title. The plan to choose Mulikihame’a was supported by many, but the decision was ultimately made by the Ngata chiefs in Hihigo. Tuku’aho felt left out and angry, having helped his father gain power, and he pressed his claim to be the next Tu’i Kanokupolu.
Tuku’aho’s tyranny and death
As a strongman, Tuku’aho ruled harshly. He fought wars in Ha’apai and Vava’u and was described by outsiders as cruel and fearsome. He is said to have burned enemies tied to trees, cut off a man’s hand, and even ordered brutal acts to intimidate people. William Mariner, a British sailor who later told stories about Tonga, described him as vindictive and cruel, though Mariner’s view came from a rival side.
In April 1799 a conspiracy led by Tupouniua and joined by other powerful figures, including Finau ‘Ulukalala II, Mulikiha’ame’a, and Fatafehi Fuanunuiava, assassinated Tuku’aho. The plot surrounded his house at night and ended his reign. The exact details are told in many accounts, but the result was clear: Tuku’aho was dead, and his death set off a long period of fighting.
Aftermath and the long civil wars
After Tuku’aho’s death, Tongatapu and the surrounding islands fell into chaos as different leaders vied for power. Finau ‘Ulukalala II became a powerful ruler in Ha’apai, and Tupouniua took a leading role in Vava’u. These rivalries sparked a civil war that did not end until 1845, when Taufa’ahau, a grandson of Tuku’aho, united Tonga. The era that began with Tuku’aho’s rise and death thus led to decades of struggle before the country was finally unified.
