The town's history dates to the era when the island was first settled with people from the
Marquesas Islands in 1100 AD. Captain
James Wilson of the
London Missionary Society arrived in 1797 on
Duff, naming the islands after the
English Admiral James Gambier who had facilitated his expedition. Before the Catholic missionaries' arrival,
cannibalism was practiced under the rule of the local kings. French
Picpus priests Father
François Caret and Father
Honoré Laval, of the
Congregation for the Sacred Hearts, landed here in 1834. They arrived from
Chile. Father
Hippolyte Roussel, who had arrived at Rikitea with more than 100
Rapa Nui people on 4 July 1871, assumed charge of Laval's Rikitea mission, and served there till he died in 1898. The figure of 9,000, mentioned by some, when Laval arrived is regarded as being hugely exaggerated. In 1825, the population was estimated at 1500. When the missionaries arrived in 1834 they counted 2,124 souls. Increasing contact with the outside world brought contagious diseases to Mangareva savagely decimating the population. There had already been several major epidemics before 1863, including one which is said have killed half the population. The story about Laval driving the population to their deaths was spread by a French judge, Louis Jacolliot, who dabbled in the occult and had a grudge against Laval and wanted to discredit him. For 9,000 people to have lived on the islands, many would have to live on the hillsides due to the small amount of flat ground, but there is no evidence of houses ever being built there. Also, if 8,500 people died because of Laval, there would be that number of graves, or at least mass graves, but there is not. ==Geography==
