Caquetio, Caiquetio, or Caiquetia, were natives of northwestern Venezuela, living along the shores of Lake Maracaibo at the time of the Spanish conquest. They moved inland to avoid enslavement by the Spaniards but were eventually destroyed as were their neighbours, the Quiriquire and the Jirajara. The Caquetíos were also present in Aruba, Curaçao and Bonaire when these islands were first discovered by Alonso de Ojeda in a.d 1499. The occupants of this region were known as Caquetíos by the Spaniards and their language (Caquetío) belongs to the Arawakan family of languages. The Caquetío and the Jirajara spoke the same language, and their cultures were quite similar. The Arawakan or Caquetío language is termed a "ghost" language because virtually no trace of it survives. Only the name remains, saved in 17th-century texts.
When the Spanish arrived in Aruba around 1500 they found the Caiquetios in Aruba, living much as they did in the Stone Age. The Caiquetios had probably migrated to Aruba, Curaçao and Bonaire in canoes made from hollowed out logs they used for fishing. Such crossings from the Paraguana peninsula in Venezuela, across the 17 miles of open sea to Aruba, would be possible in the canoes the Caiquetios of Venezuela built.
During the first years of colonization, the natives of Aruba were described by the Spaniards as Caquetíos. In addition, the Caquetíos in the mainland were the tribe geographically closest to Aruba, and archaeological evidence points towards close ties between both groups during pre-Columbian times. Perhaps as many as 600 lived in Aruba at the time of the Spanish discovery in 1499.
Together with Curaçao and Bonaire, Aruba was declared an island without use in 1513, and two years later some 2000 Caquetíos from the three islands combined were transported to Hispaniola to work in mines. These people presumably comprised the entire population of the islands, but 150 to 200 were returned to Aruba and Curaçao in 1526 to work on the exportation of brazilwood, kwihi, and divi-divi. The people returned to Aruba and Curaçao were mainly Caquetíos, but some Arawaks from other Caribbean islands were included in the group. Because of the complexity of the Aruba cave labyrinths, it is possible that they were mostly natives who had escaped deportation, but they could have been recent migrants from the mainland. In addition, substantial mainland-to-Aruba migrations of escapees occurred from 1529 to 1556, during the development of the Venezuelan colony (Haviser, 1991).
