Tabuaeran, also known as Fanning Island, is an atoll that is part of the Line Islands of the central Pacific Ocean and part of Kiribati. The land area is , and the population in 2015 was 2,315. The maximum elevation is about 3 m (10 ft) above high tide. The lagoon has an area of . The deepest water in the lagoon is about , but most of it is very shallow. Tabuaeran was first inhabited by Polynesian people. Archaeological evidence points to a single large village being maintained for several hundred years on the west side of the atoll with other scattered production and agricultural sites across the atoll. Radiometric dates range from 1100 CE to 1425 CE (Cal. 810 ±50 BP and 620 ± 60 BP at 2 sigma). Continuous habitation is likely as stratigraphic cultural layers are uninterrupted and quite deep. Some archaeologists have argued that Tabuaeran and Kiritimati were one community living across a matched set of islands as despite their relative proximity, their climates and resources differ wildly covering what would otherwise be resource shortages. While this hypothesis is still being tested, the period of human habitation on these two islands does match up. Geochemical analysis of stone tools provides a clear window into trade networks that existed throughout Polynesia and in the case of Tabuaeran, a positive match was made with a quarry located in Eiao, Marquesas. The first European to sight Tabuaeran was American captain Edmund Fanning of the American ship Betsy on June 11, 1798; it was named for him. At the time, the atoll was uninhabited and, like all of the Line Islands, had no truly native population. After Fanning, it was visited by whalers of several nationalities. The whaler had wrecked there in late 1831 or early 1832. By 1854, Captain Henry English and 150 labourers from Manihiki settled, and began producing coconut oil for export. He put the island under British protection when Captain W. H. Morshead arrived on on 16 October 1855.
