Arawak people
The Arawak were a group of people who lived in the northern part of South America, and the Carribean. After the colonization of South America, they  became extinct, within a period of about a century, to a century and a half. Today, only very few people who call themselves Arawak remain. There's also a group of languages called the Arawakian languages, which show what influence these people probably once had. Today, there are about 2000 speakers left, 1500 in Guyana, and 700 in Suriname.
