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.

Military - note
the HMAF’s primary missions are protecting the King and Tonga’s sovereignty; the HMAF has contributed small numbers of personnel to multinational military operations in Afghanistan, Iraq, and the Solomon Islands; it is a small force comprised of royal guards, marines, a few naval patrol boats, and a couple of aircraft for maritime patrolling, search and rescue, and training purposes
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 (2024)
