The Tonga flag
The Tongan flag has a red field with a white canton in the upper hoist. Inside the canton is a prominent red cross, making the design strongly associated with Christianity and the country's history.
Flag colours and symbolism
Red represents the blood of Jesus Christ, while white represents purity. The red cross reflects the importance of Christianity in Tongan society.
Flag history
Tonga's current flag dates from the 19th century and is associated with King George Tupou I and the country's adoption of Christianity. A similar design was used before the modern constitutional period, although its precise legal history has changed over time.
A short history
Tonga has a long Polynesian history and developed powerful chiefly traditions and maritime connections across the Pacific. Christian missionaries arrived in the 19th century, followed by the unification of Tonga under George Tupou I. Tonga became a British-protected state but retained its monarchy and internal self-government, becoming fully independent in 1970.

Nuku'alofa
Nuku'alofa is Tonga's capital and largest urban centre. It lies on the north coast of Tongatapu and is the country's political, commercial and transport hub.
Tongatapu
Tongatapu is Tonga's largest and most populous island and the centre of national government. Much of the island is low-lying and made up of uplifted coral limestone.
The Haʻamonga ʻa Maui
The Haʻamonga ʻa Maui is a huge trilithon of coral limestone on Tongatapu. It is one of Tonga's best-known archaeological monuments and is traditionally linked with the ancient Tuʻi Tonga dynasty.
Geography
Tonga consists of a long chain of islands and islets spread across the South Pacific. The islands include volcanic islands and low coral atolls, and the country lies east of Fiji and west of Samoa.
Climate
Tonga has a tropical maritime climate. Temperatures remain warm throughout the year, with a wetter season and a drier season. Tropical cyclones can affect the islands, particularly during the Southern Hemisphere summer.
Volcanoes and coral islands
Tonga sits near the Tonga-Kermadec subduction zone, one of the most active tectonic regions on Earth. The kingdom contains both volcanic islands and low-lying coral islands.
Humpback whales
Tonga is famous for its seasonal population of humpback whales. Whales migrate to the warm waters around Tonga to breed and give birth, making whale watching an important part of tourism.
Marine life
Tonga's waters support coral reefs, sea turtles, dolphins, tropical fish and other marine species. The health of these ecosystems is important to local communities and tourism.
Tongan culture
Tongan society places strong importance on family, community, respect and traditional hierarchy. Ceremonies, dance, music, weaving and elaborate feasts remain important parts of cultural life.
Language
Tongan is the main national language and is closely related to other Polynesian languages. English is also widely used, particularly in education, government and business.
Religion
Christianity is central to Tongan society, with several Christian denominations represented. Sunday is traditionally treated as a particularly important day of worship and rest.
Traditional dance and music
Traditional Tongan performance includes lakalaka, a formal group dance involving singing, movement and carefully coordinated gestures. It is an important part of national cultural heritage.
Food
Tongan food commonly includes root crops, coconut, fish, pork and taro. Traditional feasts may feature underground-oven cooking known as an umu.
Economy
Tonga's economy depends on agriculture, fishing, tourism, remittances and services. Because of its small population and remote location, overseas remittances are particularly important.
Agriculture
Important crops include coconuts, squash, taro, yams and bananas. Tonga also exports agricultural produce, although farming is vulnerable to cyclones and other extreme weather.
The monarchy
Tonga is a constitutional monarchy and one of the few remaining monarchies in the Pacific. The modern Tongan monarchy traces its roots to the unification of the islands under George Tupou I.
Why is Tonga's flag interesting?
Tonga's flag is one of the world's oldest continuously used national flags. Its simple red-and-white design and cross reflect the country's strong Christian heritage and its long history as a Polynesian kingdom.
