Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and northwest of Vanuatu. It has a land area of 28,400 square kilometres (11,000 sq mi), and a population of approximately 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands.

The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called "the Solomons" by those who later received word of his voyage and mapped his discovery. Mendaña returned decades later, in 1595, and another Spanish expedition, led by Portuguese navigator Pedro Fernandes de Queirós, visited the Solomons in 1606. Britain defined its area of interest in the Solomon Islands archipelago in June 1893, when Captain Gibson, R.N., of HMS Curacoa, declared the southern Solomon Islands a British protectorate. During World War II, the Solomon Islands campaign (1942–1945) saw fierce fighting between the United States, British Commonwealth forces and the Empire of Japan, including the Battle of Guadalcanal.

The official name of the then-British administration was changed from the "British Solomon Islands Protectorate" to "The Solomon Islands" in 1975, and self-government was achieved the following year. Independence was obtained, and the name changed to just "Solomon Islands" (without the definite article), in 1978. At independence, Solomon Islands became a constitutional monarchy. The King of Solomon Islands is Charles III, who is represented in the country by a governor-general.
