Hawaii Island Kamehameha was raised in the royal court of his uncle Kalaniʻōpuʻu. He achieved prominence in 1782, upon Kalaniʻōpuʻu's death. While the kingship was inherited by
Kīwalaʻō, Kalaniʻōpuʻu's son, Kamehameha was given a prominent religious position as guardian of the Hawaiian god of war,
Kūkaʻilimoku. He was also given control of the district of
Waipiʻo Valley. The two cousins' relationship was strained after Kamehameha made a
dedication to the gods instead of allowing Kīwalaʻō to do that. Kamehameha accepted the allegiance of a group of chiefs from the
Kona district. The other story took place after the prophecy was passed along by the high priests and high chiefs. When Kamehameha was able to lift the
Naha Stone, he was considered the fulfiller of the prophecy. Other ruling chiefs, Keawe Mauhili, the Mahoe (twins) Keoua, and other chiefs rejected the prophecy of Ka Poukahi. The high chiefs of Kauai supported Kiwalaʻo even after learning about the prophecy. The five Kona chiefs supporting Kamehameha were
Keʻeaumoku Pāpaʻiahiahi (Kamehameha's father-in-law/grand uncle),
Keaweaheulu Kaluaʻāpana (Kamehameha's uncle), Kekūhaupiʻo (Kamehameha's warrior teacher), and
Kameʻeiamoku and
Kamanawa (twin uncles of Kamehameha). They defended Kamehameha as the unifier Ka Naʻi aupuni. High Chiefs Keawe Mauhili and Keeaumoku were by genealogy the next in line for aliʻi nui. Both chose the younger nephews Kīwalaʻō and Kamehameha over themselves. Kīwalaʻō was soon defeated in the first key conflict, the
Battle of Mokuʻōhai. Kamehameha and his chiefs took over Konohiki responsibilities and sacred obligations of the districts of Kohala, Kona, and Hāmākua on Hawaiʻi. The prophecy included far more than the island of Hawaiʻi. It went across and beyond the Pacific Islands to the semi-continent of
Aotearoa (New Zealand). He was supported by his most political wife
Kaʻahumanu and father, High Chief Keeaumoku. Senior counselor to Kamehameha, she became one of Hawaiʻi's most powerful figures. Kamehameha and his council of chiefs planned to unite the rest of the Hawaiian Islands. Allies came from British and American traders, who sold guns and ammunition to Kamehameha. Another major factor in Kamehameha's continued success was the support of Kauai chief Kaʻiana and Captain William Brown of the
Butterworth Squadron. He guaranteed Kamehameha unlimited gunpowder from
Qing China and gave him the formula for gunpowder:
sulfur,
saltpeter, and
charcoal, all of which are abundant in the islands. Two westerners who lived on Hawaiʻi island,
Isaac Davis and
John Young, married native Hawaiian women and assisted Kamehameha.
Olowalu Massacre In 1789,
Simon Metcalfe had been captaining a
fur-trading vessel, the
Eleanora, while his son,
Thomas Humphrey Metcalfe, captained the ship along the Pacific
Northwest Coast; the two parties were to rendezvous in the
Hawaiian Islands.
Fair American was held up when it was captured by the Spanish at
Nootka Sound and taken to
San Blas, Nayarit, where it was soon released. The
Eleanora finally arrived in 1790, where it was greeted by Chief
Kameʻeiamoku. During their interactions, the chief allegedly offended or insulted Captain Metcalfe, who then struck the chief with the end of a rope. Sometime later, while docked in Honolua,
Maui, a small boat—which was tied to the larger ship, and had a crewman inside—was stolen by native islanders. When Metcalfe discovered where the boat was taken, he sailed directly to the village of
Olowalu. There, he confirmed that the boat had been broken apart and the shipmate murdered. Previously, Metcalfe had resorted to violence when he fired
muskets into another village near where he had been anchored, ultimately killing some of the residents. This time, furious, Metcalfe took aim at Olowalu, ordering all
cannons aboard the ship to be moved to one side, facing the island. As the captain initiated his trading calls and greetings to the locals, hundreds of people—men, women, children and elderly—ventured down to the beach to trade, on foot and by canoe. When the islanders were within range, Metcalfe ordered
broadsides to be fired on the Hawaiians, killing over 100 of them. Six weeks later,
Fair American was stuck near the
Kona coast of Hawaii, where Chief Kameʻeiamoku was living, near
Kaʻūpūlehu. Kameʻeiamoku had decided to attack the next foreign ship to avenge the strike by the elder Metcalfe. He canoed out to the ship with his men, where he killed Metcalfe's son and all but one (Isaac Davis) of the five crewmen. Kamehameha took Davis into protection and took possession of the ship.
Eleanora was at that time anchored at
Kealakekua Bay, where the ship's
boatswain had gone ashore and been captured by Kamehameha's forces because Kamehameha believed Metcalfe was planning more revenge.
Eleanora waited several days before sailing off, apparently without knowledge of what had happened to
Fair American or Metcalfe's son. Davis and ''Eleanora's'' boatswain, John Young, tried to escape, but were treated as chiefs, given wives and settled in Hawaii.
Invasion of Maui In 1790, while the aliʻi
Kahekili II was on Oʻahu, Kamehameha's army invaded Maui with the assistance of John Young and Isaac Davis. Using cannons from the
Fair American, they defeated Maui's army led by Kahekili's son
Kalanikūpule at the bloody
Battle of Kepaniwai . In 1791, Kahekili, supported by his brother
Kāʻeokūlani, aliʻi of Kauaʻi, reconquered Maui and also acquired cannons. In April or May 1791, Kahekili tried to invade the island of Hawaiʻi, but was defeated in a naval battle called Kepuwahaʻulaʻula near
Waipiʻo.
Death of Keōua Kuahuula In 1790,
Keōua Kūʻahuʻula, who came to rule the districts of Kaʻū and
Puna, took advantage of Kamehameha's absence in Maui and began raiding the west coast of Hawaii. He also advanced against the district of Hilo, deposing his uncle
Keawemaʻuhili. In a series of skirmishes, Kamehameha's forces pushed Kalanikūpule's men back until they were cornered on the
Pali Lookout. While Kamehameha moved on the Pali, his troops took heavy fire from the cannon. He assigned two divisions of his best warriors to climb to the Pali to attack the cannons from behind; they surprised Kalanikūpule's gunners and took control. With the loss of their guns, Kalanikūpule's troops fell into disarray and were cornered by Kamehameha's still-organized troops. A
fierce battle at Nuʻuanu ensued, with Kamehameha's forces forming an enclosing wall. Using traditional Hawaiian spears, as well as muskets and cannon, they killed most of Kalanikūpule's forces. Over 700 men were forced over the Pali's cliff, a drop of 1,000 feet. Kaʻiana was killed during the action; Kalanikūpule was later captured and
sacrificed to Kūkāʻilimoku.
Kauaʻi and rebellion of Nāmakehā After his conquest of Oahu in the summer of 1795, Kamehameha I prepared his forces for the conquest of
Kauaʻi, the last remaining island kingdom out of his control. In the spring of 1796, he attempted to continue with his forces to Kauaʻi but he lost many of his canoes in the strong winds and rough seas of the Kaʻieʻie Waho channel. He returned to Hawaii to pacify the rebellion of
Nāmakehā (brother of Kaʻiana) in Hilo and ruled from Hawaii for the next six years as he consolidated his conquests and prepared for a second invasion of Kauaʻi. At Hilo, Kamehameha I commissioned the building of a large fleet of 800 (according to Kamakau) double-hulled war canoes called
peleleu along with Western schooners, and he also stockpiled large number of guns, canons and ammunition. He took his
peleleu to Maui where he stayed from 1802 to 1803 and then to Oʻahu in late 1803 or early 1804. While in Oʻahu, a large percentage of his force was killed by the
maʻi ʻokuʻu epidemic, which was thought to be either
cholera or
bubonic plague. Kamehameha I contracted the illness but survived. The second invasion of Kauaʻi was postponed. By now, the succession crisis on Kauaʻi had resolved, with Kāʻeokūlani's son,
Kaumualiʻi, emerging as the new king. In April 1810, Kamehameha I negotiated the peaceful unification of the islands with Kaumualiʻi. His court genealogist and high priest
Kalaikuʻahulu was instrumental in the monarch's decision to leave Kaumualiʻi as a
tributary king rather than killing him, when he was the single member of the aliʻi council to agree with Kamehameha's own reluctance to do so. The other aliʻi continued with the plan to poison Kaumualiʻi when
Isaac Davis warned him, making the ruler cut his trip short and return to Kauaʻi, leaving Davis to be poisoned by the aliʻi instead. ==Aliʻi Moʻi of the Hawaiian Islands==
