Contact with Europeans began in the early 18th century. Jacob Roggeveen, a Dutchman, was the first known non-Polynesian to sight the Samoan islands in 1722. This visit was followed by French explorer Louis-Antoine de Bougainville, who named them the ''Navigator Islands'' in 1768. Contact was limited before the 1830s, which is when English missionaries, whalers and traders began arriving.
