Tonga
The last Polynesian kingdom
Tonga is the only Pacific nation never formally colonized and the last surviving Polynesian monarchy, an archipelago of more than 170 islands south of Samoa where a king still reigns and traditional rank and custom shape daily life. Scattered across the southern Pacific, its islands range from raised coral platforms to active volcanoes, and in 2022 the violent eruption of the undersea volcano Hunga Tonga-Hunga Ha'apai sent a shockwave around the world. Nuku'alofa, on the main island of Tongatapu, is the capital of this proud island kingdom.
Tonga's islands fall into two parallel chains: a western volcanic line, including active volcanoes, and an eastern line of low, raised coral islands. The highest point, on the volcanic island of Kao, reaches 1,033 meters. Most people live on flat, fertile Tongatapu in the south. The country sits on the seismically active Tonga Trench, one of the deepest parts of the ocean, and lies in the cyclone belt, making it prone to earthquakes, eruptions, and severe storms. The climate is tropical, warm and humid, with a distinct wet season.
Polynesians settled Tonga around three thousand years ago, and the islands once dominated a maritime empire across the western Pacific. A unified kingdom emerged in the nineteenth century under King George Tupou I, and Tonga preserved its sovereignty as a British-protected state before resuming full independence in 1970. The monarchy remains central to national identity, though recent decades have brought democratic reforms. The economy depends on agriculture, fishing, tourism, and remittances from Tongans living abroad.
