The Pacific’s Last Kingdom
Tonga is the only Pacific country never fully colonised — the Tongan monarchy has ruled continuously since at least 950 AD (by traditional count, even longer), making it one of the world’s oldest continuous monarchies. The country was a British “protected state” 1900-1970 — giving Britain control of foreign affairs — but never fully annexed. The Tuʻi Tonga dynasty ruled from c. 950 AD; the current House of Tupou since 1845.
The country has been a constitutional monarchy since 2010 — reforms that gave more power to parliament while retaining the monarchy. King Tupou VI is the reigning monarch.
Tonga is a rugby-mad country — ranking highest per capita in World Rugby’s global standings some years — and has produced numerous elite players for New Zealand (All Blacks), Australia, England, and in the NRL.
The country experienced an unprecedented volcanic disaster in January 2022 — the eruption of the underwater Hunga Tonga-Hunga Haʻapai volcano was one of the most powerful volcanic events in recorded history, producing the tallest volcanic plume ever observed (~58 km), generating a tsunami, severing Tonga’s undersea internet cable, and covering the country in ash for weeks.
Tongan waters host humpback whale calving grounds — one of few places in the world where swimming with humpback whales is legally permitted (July-October). This has become a major ecotourism draw.
