Jamaican literature is internationally renowned, with the island of Jamaica being the home or birthplace of many important authors. One of the most distinctive aspects of Jamaican literature is its use of the local dialect — a variation of English, the country's official language. Known to Jamaicans as "patois", and now sometimes described as "nation language", this creole has become an important element in Jamaican fiction, poetry and theater. Notable writers and intellectuals from elsewhere in the Caribbean region studied at the University of the West Indies in Kingston, including St. Lucian Nobel prize-winner, Derek Walcott, the late Guyanese historian and scholar Walter Rodney, and Grenadian poet and short story writer Merle Collins. Folk beginnings The tradition of storytelling in Jamaica is a long one, beginning with folktales told by the slaves during the colonial period. Jamaica's folk stories are most closely associated with those of the Ashanti tribe in West Africa, from which many of the slaves originated. Some European tales were also brought to the island by immigrants, particularly those from the United Kingdom. In folktales, the local speech style is particularly necessary. It infuses humor into the stories, and is an integral part of the retelling. Perhaps the most popular character in Jamaican tales, Anancy (also spelled Anansi, 'Nancy Spida, and Brer Nansi) is an African spider-god who makes an appearance in tales throughout the Caribbean region. He is a trickster god, and often goes against other animal-god characters, like Tiger and Donkey, in his stories. These stories are thought to be one way the slaves told about outsmarting their owners as well. Development of the literature Jamaican Thomas MacDermot (1870–1933) is credited with fostering the creation of Jamaican literature (according to critic Michael Hughes, MacDermot was "probably the first Jamaican writer to assert the claim of the West Indies to a distinctive place within English-speaking culture"), and his Becka's Buckra Baby as the beginning of modern Caribbean literature. Jamaican-born Claude McKay (1889–1948) is credited with inspiring France's Negritude (“Blackness”) movement, as well as being a founding father of the Harlem Renaissance. Having established himself as a poet in Jamaica, he moved to the U.S. in his 20s and proceeded to travel to France, but never returned to his birthplace. Una Marson (1905–1965) was also well known for her poetry, her activism as a feminist, and for her role as producer of the BBC literary radio programme
