On 14 January 2022, the uninhabited volcanic island of Hunga Tonga once more erupted. Located 65 km (40 mi) north of Tongatapu, Tonga's main island, it is part of the highly active Tonga–Kermadec Islands volcanic arc. The eruption caused damaging tsunamis along the entire rim of the Pacific Ocean and was the largest of the 21st century to that date. The satellite photo shows the volcanic cloud from directly overhead just hours after the start of the eruption. Image courtesy of the Japan Meteorological Agency.

Introduction

Background

The first humans arrived in Tonga around 1000 B.C. The islands’ politics were probably highly centralized under the Tu’i Tonga, or Tongan king, by A.D. 950, and by 1200, the Tu’i Tonga had expanded his influence throughout Polynesia and into Melanesia and Micronesia. The Tongan Empire began to decline in the 1300s, descending into civil wars, a military defeat to Samoa, and internal political strife that saw successive leaders assassinated. By the mid-1500s, some Tu’i Tongans were ethnic Samoan and day-to-day administration of Tonga was transferred to a new position occupied by ethnic Tongans.

Dutch sailors explored the islands in the 1600s and British Captain James COOK visited Tonga three times in the 1770s, naming them the Friendly Islands for the positive reception he thought he received, even though the Tongans he encountered were plotting ways to kill him. In 1799, Tonga fell into a new round of civil wars over succession. Wesleyan missionaries arrived in 1822, quickly converting the population. In the 1830s, a low-ranking chief from Ha’apai began to consolidate control over the islands and won the support of the missionaries by declaring that he would dedicate Tonga to God. The chief soon made alliances with leaders on most of the other islands and was crowned King George TUPOU I in 1845, establishing the only still-extant Polynesian monarchy. TUPOU I declared Tonga a constitutional monarchy in 1875 and his successor, King George TUPOU II, agreed to enter a protectorate agreement with the UK in 1900 after rival Tongan chiefs tried to overthrow him. As a protectorate, Tonga never completely lost its indigenous governance, but it did become more isolated and the social hierarchy became more stratified between a group of nobles and a large class of commoners. Today, about one third of parliamentary seats are reserved for nobles.

Queen Salote TUPOU III negotiated the end of the protectorate in 1965, which was achieved under King TUPOU IV, who in 1970 withdrew from the protectorate and joined the Commonwealth of Nations. A prodemocracy movement gained steam in the early 2000s, led by future Prime Minister ‘Akilisi POHIVA, and in 2006, riots broke out in Nuku’alofa to protest the lack of progress on prodemocracy legislation. To appease the activists, in 2008, King George TUPOU V announced he was relinquishing most of his powers leading up to parliamentary elections in 2010; he died in 2012 and was succeeded by his brother ‘Aho’eitu TUPOU VI. Tropical Cyclone Gita, the strongest-ever recorded storm to impact Tonga, hit the islands in February 2018 causing extensive damage.

Economy

Economic overview

Tonga has a small, open island economy and is the last constitutional monarchy among the Pacific Island countries. It has a narrow export base in agricultural goods. Squash, vanilla beans, and yams are the main crops. Agricultural exports, including fish, make up two-thirds of total exports. Tourism is the second-largest source of hard currency earnings following remittances. Tonga had 53,800 visitors in 2015. The country must import a high proportion of its food, mainly from New Zealand.

 

The country remains dependent on external aid and remittances from overseas Tongans to offset its trade deficit. The government is emphasizing the development of the private sector, encouraging investment, and is committing increased funds for health care and education. Tonga's English-speaking and educated workforce offers a viable labor market, and the tropical climate provides fertile soil. Renewable energy and deep-sea mining also offer opportunities for investment.

 

Tonga has a reasonably sound basic infrastructure and well developed social services. But the government faces high unemployment among the young, moderate inflation, pressures for democratic reform, and rising civil service expenditures.

Telecommunication systems

general assessment: high speed Internet provided by 3 MNOs, has subsequently allowed for better health care services, faster connections for education and growing e-commerce services; in 2018 new 4G LTE network; fixed-line teledensity has dropped given mobile subscriptions; mobile technology dominates given the island's geography; satellite technology is widespread and is important especially in areas away from the city; the launch in 2019 of the Kacific-1 broadband satellite has made broadband more widely available for around 89 remote communities (2020)

domestic: fixed-line 7 per 100 persons and mobile-cellular teledensity 59 telephones per 100; fully automatic switched network (2020)

international: country code - 676; landing point for the Tonga Cable and the TDCE connecting to Fiji and 3 separate Tonga islands; satellite earth station - 1 Intelsat (Pacific Ocean) (2020)

note: the COVID-19 pandemic continues to have a significant impact on production and supply chains globally; since 2020, some aspects of the telecom sector have experienced a downturn, particularly in mobile device production; progress toward 5G implementation has resumed, as well as upgrades to infrastructure; consumer spending on telecom services has increased due to the surge in demand for capacity and bandwidth; the crucial nature of telecom services as a tool for work and school from home is still evident, and the spike in this area has seen growth opportunities for development of new tools and increased services

Military - note

Tonga participated in World War I as part of the New Zealand Expeditionary Force, but the Tonga Defense Force (TDF) was not established until 1939 at the beginning of World War II; in 1943, New Zealand helped train about 2,000 Tongan troops who saw action in the Solomon Islands; the TDF was disbanded at the end of the war, but was reactivated in 1946 as the Tonga Defense Services (TDS); in 2013, the name of the TDS was changed to His Majesty’s Armed Forces of Tonga (HMAF); Tongan troops deployed to Iraq from 2004-2008 and Afghanistan to support UK forces from 2010-2014

Tonga has a "shiprider" agreement with the US, which allows local maritime law enforcement officers to embark on US Coast Guard (USCG) and US Navy (USN) vessels, including to board and search vessels suspected of violating laws or regulations within Tonga's designated exclusive economic zone (EEZ) or on the high seas; "shiprider" agreements also enable USCG personnel and USN vessels with embarked USCG law enforcement personnel to work with host nations to protect critical regional resources (2022)
