The primary use of the term Oceania is to describe a continental region (like Europe or Africa) that lies between Asia and the Americas, with Australia as the major land mass. The name Oceania is used, rather than Australasia, because unlike the other continental groupings, it is the ocean rather than the continent that links the nations together. Oceania is the smallest continental grouping in land area and the second smallest, after Antarctica, in population.
The Kingdom of Tonga (Tongan for "south") is an archipelago in the southern Pacific Ocean consisting of 169 islands, 36 of them inhabited, and is divided into three main groups – Vava'u, Ha'apai, and Tongatapu, which together cover an 800-kilometre (500 miles)-long north–south line. Tonga is a monarchy. Criticism of the monarch is held to be antithetical to Tongan culture and etiquette.
The largest island, Tongatapu, on which the capital city of Nuku'alofa is located, covers 257 square kilometres (99 sq mi). The population is 112,422 (2005 est).
Rennell Island has a population of about 3000 persons of Polynesian descent who primarily speak Renbelian, Pigin and some English. Rennell and Bellona Islands are the only islands in the Melanesian Solomon Island archipelago classified Polynesian. It is located 236 kilometres (147 mi) South of Honiara. The capital of the Province, Tigoa, is located at the Western end of the island.
The population of Renbel dates before 1400 AD when clansmen left Uvea (now Wallis Island) and crossed the Pacific ocean to settle on the islands. Captain Butler of HMS Walpole discovered the islands in 1801. During the Pacific campaign of World War II Japanese Nakajima A6M2-NRufe floatplanes operated from Lake Tegano until American PBY Catalinas used the lake as a base after 1943. The Battle of Rennell Island was the last major naval battle of the Guadacanal Campaign which occurred between 29 January 1943 and 30 January 1943.
