Tarawa is an atoll and the capital of the Republic of Kiribati in the central Pacific Ocean. It includes North Tarawa, which has much in common with the other, more distant islands of the Gilberts group; and South Tarawa, home to 50,182 people as of 2010—half the country's total population. The atoll is best known to outsiders as the site of the Battle of Tarawa during World War II.
Tarawa has a large lagoon with a total area of 500 square kilometers (193 sq mi) and a wide reef. Despite the natural abundance of fish and shellfish of all kinds, marine resources are being depleted by large and growing populations. Droughts are common, but in normal years there is enough rainfall to support breadfruit, papaya and banana trees, as well as coconut and pandanus.
North Tarawa consists of a number of islets, the northernmost of which is Buariki. The islets are separated in places by wide straits, which are best crossed at low tide.
In South Tarawa, the construction of dykes has created a single strip of land from Betio in the west to Buota in the northeast.
In Kiribati mythology, Tarawa was the land when the earth, ocean and sky were not yet split by the spider Naro. Thus, having called the sky "carawa" and the ocean "marava", he named the piece of rock on which "Riiki" (another god Naro found) stood when he lifted the sky, "Tarawa". Naro then created the remaining islands of Kiribati, as well as Samoa.
Humans arrived on these islands thousands of years ago, and migrations to and from Kiribati have occurred since ancient times.
Evidence from a number of sources, including radiocarbon dating and DNA analysis, confirms that exploration of the Pacific Ocean included the settlement of the Gilbert Islands by about 200 BC. The people of Kiribati are still excellent seafarers, able to cross the ocean in locally made ships using traditional navigation methods.
Thomas Gilbert, captain of the East India Company vessel Charlotte, was the first European to describe Tarawa, arriving there on June 20, 1788. He named it Matthew Island in honor of the owner of his ship, the Charlotte. He named the lagoon Charlotte Bay. Gilbert's 1788 sketches survive.
Tarawa Post Office opened on 1 January 1911.
Sir Arthur Grimble was an administrative officer cadet at Tarawa (1913–1919); and became Resident Commissioner of the Gilbert and Ellice Islands Colony in 1926.
During World War II, Tarawa was occupied by the Japanese, and beginning on November 20, 1943, the bloody Battle of Tarawa took place there. That day, US Marines landed on Tarawa and suffered heavy casualties from Japanese soldiers manning trenches on the atoll. The Marines captured the island after 76 hours of intense fighting, in which a total of about 6,000 people died on both sides.
In 2014, the Kiribati government began a road rehabilitation project, partially funded by the World Bank, to covering the main road between Betio in the west and Bonriki in the east, upgrading the main road through Tarawa from a dirt road.
