  • Sacred Kingship: Cases from Polynesia
    Sacred Kingship: Cases from Polynesia Henri J. M. Claessen Leiden University ABSTRACT This article aims at a description and analysis of sacred kingship in Poly- nesia. To this aim two cases – or rather island cultures – are compared. The first one is the island of Tahiti, where several complex polities were found. The most important of which were Papara, Te Porionuu, and Tautira. Their type of rulership was identical, so they will be discussed as one. In these kingdoms a great role was played by the god Oro, whose image and the belonging feather girdles were competed fiercely. The oth- er case is found on the Tonga Islands, far to the west. Here the sacred Tui Tonga ruled, who was allegedly a son of the god Tangaloa and a woman from Tonga. Because of this descent he was highly sacred. In the course of time a new powerful line, the Tui Haa Takalaua developed, and the Tui Tonga lost his political power. In his turn the Takalaua family was over- ruled by the Tui Kanokupolu. The tensions between the three lines led to a fierce civil war, in which the Kanokupolu line was victorious. The king from this line was, however, not sacred, being a Christian. 1. INTRODUCTION Polynesia comprises the islands situated in the Pacific Ocean within the triangle formed by the Hawaiian Islands, Easter Island and New Zealand. The islanders share a common Polynesian culture. This cultural unity was established already in the eighteenth century, by James Cook, who ob- served during his visit of Easter Island in 1774: In Colour, Features, and Languages they [the Easter Islanders] bear such an affinity to the People of the more Western isles that no one will doubt that they have the same Origin (Cook 1969 [1775]: 279, 354–355).

  • Christianity and Taufa'āhau in Tonga
    Melanesian Journal of Theology 23-1 (2007) CHRISTIANITY AND TAUFA‘ĀHAU IN TONGA: 1800-1850 Finau Pila ‘Ahio Revd Dr Finau Pila ‘Ahio serves as Principal of the Sia‘atoutai Theological College in Tonga. INTRODUCTION Near the centre of the Pacific Ocean lies the only island kingdom in the region, and the smallest in the world, Tonga. It is a group of small islands, numbering about 150, with only 36 of them inhabited, and which are scattered between 15º and 23º south latitude, and between 173º and 177º west longitude. The kingdom is divided into three main island groups: Tongatapu, situated to the south, Ha‘apai, an extensive archipelago of small islands in the centre, and Vava‘u, in the north. Tonga lies 1,100 miles northeast of New Zealand, and 420 miles southeast of Fiji. With a total area of 269 square miles, the population is more than 100,000, most of whom are native Polynesians. Tonga is an agricultural country, and most of the inhabited islands are fertile. The climate, however, is semi-tropical, with heavy rainfall and high humidity. Tonga, along with the rest of the Pacific, was completely unknown to Europe until the exploration of the area by the Spaniards and Portuguese during the 16th century. These explorers were seeking land to establish colonies, and to convert the inhabitants to Christianity. By the second decade of the 17th century, more explorers from other parts of Europe came into the area, to discover an unknown southern continent called “Terra Australis Incognita”, between South America and Africa. Among these, the Dutch were the first Europeans to discover Tonga.

  • Pollen Evidence for Plant Introductions in a Polynesian Tropical Island Ecosystem, Kingdom of Tonga 253
    Pollen evidence for plant introductions in a Polynesian tropical island ecosystem, Kingdom of Tonga 253 14 Pollen evidence for plant introductions in a Polynesian tropical island ecosystem, Kingdom of Tonga Patricia L. Fall School of Geographical Sciences, Arizona State University, Tempe, United States [email protected] Introduction The dynamic nature of tropical Pacific ecosystems results from chance migrations and the evolution of founder species, as well as from physical factors such as changes in sea level, ocean currents, tectonic processes and climate (Hope 2001). In addition, this region’s vegetation is constantly adjusting through succession to local perturbations like landslides and tropical cyclones. These ecological and physical processes are compounded by continued immigration of new species, competition, extinctions and extirpation of species. For many island ecosystems the most dramatic impact on species composition results from the arrival of humans and their ‘co-voyaging’ plants and animals (Hope 2001). The degree to which climatic or other natural variations, versus human impacts, have caused recent environmental fluctuations in island ecosystems is an ongoing debate (cf. Nunn 1994; Burney 1997). In this paper, I examine palynological evidence for plants introduced to several islands in the three main island groups of Tongatapu, Ha’apai and Vava’u in the Kingdom of Tonga. My purpose is to briefly document the history of the tropical rainforests of Tonga as they can be reconstructed from pollen cores, to understand the role that humans played in the development of the Tongan flora, and to discuss plant introductions to the islands by both Polynesian and later European settlers. Losses or increases in plant species on remote islands are controlled by many factors, including habitat change, natural factors, and loss of dispersers or pollinators.

  • A Brief History of the Tongan Military from the Late Nineteenth Century to the Present
    TAU: A BRIEF HISTORY OF THE TONGAN MILITARY FROM THE LATE NINETEENTH CENTURY TO THE PRESENT A THESIS SUBMITTED TO THE GRADUATE DIVISION OF THE UNIVERSITY OF HAWAI‘I AT MĀNOA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS IN HISTORY May 2019 Amanda L. SullivanLee Thesis Committee: David Hanlon, Chairperson David Chappell John Rosa i © Amanda L. SullivanLee ii Abstract This thesis focuses on the origins of the modern Tongan Military from the establishment of the Tongan monarchy in 1875 to the Military’s most recent engagements into the 21st Century. This thesis offers an overview of the existing literature on Tongan history and military as well as an overview of contemporary literature that critiques militarization in the Pacific. Through a historical and critical lens, I examine the Tongan Military’s participation in WWI, WWII, the Regional Assistance Mission to Solomon Islands (RAMSI), the U.S. invasions of Iraq and Afghanistan, and the quelling of the 2006 Democracy Riots. Chapter one focuses on the establishment of Tonga as a British Protectorate, chapter two offers an account of Tonga’s involvement in WWI, chapter three extends this account with an exploration of WWII, and chapter four offers a look at more contemporary engagements of the Tongan Military. By tracing the country’s military, this thesis centers on exploring two main questions: for whom is the Tongan military fighting, and what impacts does Tongan participation in foreign military campaigns have on the island kingdom’s sovereignty? iii Acknowledgements This thesis would not have been possible without the support of my supportive and dedicated committee.

  • Island of Tonga
    Overview Tongans have a way of doing things whole heartedly, whether its talking among themselves orIsland entertaining of guests. Tonga For example, tables (or, traditionally, mats) at a Tongan feast are heaped high with food, and the enthusiasm with which the men and women perform their lakalaka, mauluulu and other dances is infectious with energy. As you'll quickly learn, it's easy to see that these culturally rich people come from the "Friendly Islands." Location Tonga is located about two-thirds of the way between Hawai'i and New Zealand, southwest of Samoa and east of Fiji. Geography The approximately 170 islands in the Kingdom of Tonga are divided among three groups: Tongatapu, which derives its name from the main island where the capital of Nukualofa is located; Ha'apai, a series of smaller islands to the north of Tongatapu; and Vava'u, the northernmost islands. Unlike the homes of their Polynesian cousins, most Tongan islands are relatively low-lying but very fertile. Population According to WORLD BANK there were approximately 108,000 Tongans living in the kingdom as of 2017, almost all of them Polynesians. Roughly 60% of the population lives on the main island of Tongatapu, which means "sacred Tonga." In addition, there are significant communities of Tongans living in American Samoa, Hawai'i, California and Utah; and also in New Zealand and Australia. Over the past centuries, Tongans spread widely over the western part of Polynesia. Additionally, many people in Samoa, Uvea, Futuna, and the Lau Islands of Fiji share Tongan blood. History and Discovery Like all their Polynesian cousins, the Tongans did not have a written language to record their early history; but anthropologists recognize them as being among the most ancient of the Polynesians who probably migrated to their islands about 3,000 years ago.

    H.

M. CLAESSEN TONGAN TRADITIONS - ON MODEL- BUILDING AND HISTORICAL EVIDENCE Introduction During the past several years various scholars have tried, with the help of models, to unravel the complex history of the leading families of the Tonga Islands. In 1978, Adrienne Kaeppler published a study in which she applied the model of the circulating connubium (an asymmetrical system of exchange of spouses) to the marriages of the leading families of Tonga, Samoa, and Fiji. Kaeppler tried to support her views by postula- ting the existence of a system of exchange of goods between the three islands. She acknowledged, however, that the evidence for such an exchange of goods between Samoa and Fiji was limited, and that the Samoans she had consulted 'had difficulty thinking of any Samoan/ Fijian marriages' (Kaeppler 1978:250). Notwithstanding the weaknesses of her argument, Kaeppler's views were accepted and elaborated on by Friedman (1981,1982). Friedman used the Kaeppler hypothesis as the cornerstone of a lengthy theoretical discussion. This led him to hypothesize not only about the existence of a circulating connubium, but also about that of a system of prestige goods in Western Polynesia. Friedman not only relied on Kaeppler's views, but also referred in several instances to a study by Hjarno on social repro- duction in aboriginal Samoa (Hjarno 1979/80).
