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.

note: paved runways have a concrete or asphalt surface but not all have facilities for refueling, maintenance, or air traffic control; the length of a runway required for aircraft to safely operate depends on a number of factors including the type of aircraft, the takeoff weight (including passengers, cargo, and fuel), engine types, flap settings, landing speed, elevation of the airport, and average maximum daily air temperature; paved runways can reach a length of 5,000 m (16,000 ft.), but the “typical” length of a commercial airline runway is between 2,500-4,000 m (8,000-13,000 ft.)

note: unpaved runways have a surface composition such as grass or packed earth and are most suited to the operation of light aircraft; unpaved runways are usually short, often less than 1,000 m (3,280 ft.) in length; airports with unpaved runways often lack facilities for refueling, maintenance, or air traffic control
