Introduction
Tonga, known as the Friendly Islands, is the only remaining Polynesian monarchy and maintains a strong cultural identity rooted in centuries of tradition. It consists of more than 170 islands spread across the South Pacific.
Geography
Tonga covers 747 sq km and comprises 176 islands, of which 36 are inhabited. The islands are grouped into Tongatapu, Ha’apai, and Vava’u, with additional isolated northern and southern islands. The terrain includes volcanic high islands and coral atolls, with a tropical climate influenced by trade winds.
People and Society
Tonga’s estimated 2025–2026 population is around 104,000, predominantly Tongan (96.5%), with small minorities of other Pacific and Asian groups. Tongan is the primary language, and Protestant Christianity is the dominant religion. Population growth is slightly negative, reflecting demographic challenges.

Tonga is a hereditary constitutional monarchy with a Legislative Assembly that includes both elected representatives and nobles. The monarch, King Tupou VI, serves as head of state, while the prime minister leads government operations.
