Tonga Overview & Key Facts

Brief History of Tonga

Tonga is the only Pacific nation never formally colonized, maintaining its monarchy for over 1,000 years. The Tu’i Tonga dynasty began around 950 AD, followed by the current Tupou dynasty established in 1845. Captain James Cook named the islands “Friendly Islands” in 1773 and 1777. Christian missionaries arrived in the 19th century, and King George Tupou I unified the kingdom and abolished slavery. Tonga became a constitutional monarchy in 1875 and joined the Commonwealth in 1970 while retaining full independence.

Independence & National Identity

• Independence date: June 4, 1970 (from British protectorate).

Tonga proudly remains the Pacific’s last kingdom. The national flag features a red field with white canton and red cross symbolizing Christianity. The royal family retains significant influence, and traditional rank and respect (fatongia) remain central to Tongan society.

Government System & Current Leadership

• Type of government: Constitutional Monarchy
• Current king: Tupou VI (since 2012)
