Indo-Grenadians, or Grenadians who trace their roots to India, form the largest minority group in Grenada. This term is not generally recognized by Grenadian's or indeed Caribbeans. They usually refer to themselves simply as Grenadian or possibly Caribbean. This group was first introduced during the second half of the 19th century when Grenada experimented with indentured labour. By the second half of the 20th century Indians were so integrated into Grenada’s society that a distinct Indian cultural identity was generally invisible. In addition, Indians were involved in every aspect of Grenadian life. Currently there are over 12,000 Grenadians of Indian and mixed-Indian descent (11% of the total population).
