When Europeans first arrived in Tahiti at the end of the 18th century, there was no writing system and Tahitian was only a spoken language. In 1797, Protestant missionaries arrived in Tahiti on a British ship called the Duff, captained by James Wilson. Among the missionaries was Henry Nott (1774–1844) who learned the Tahitian language and worked with Pōmare II, a Tahitian king, to translate the English Bible into Tahitian. A system of 5 vowels and 9 consonants was adopted for the Tahitian Bible which would become the key text by which many Polynesians would learn to read and write.
