The French and English, intent on self-enrichment through exploitation of the island's natural resources, soon encountered resistance, with the native Caribs (Kalinago) waging war throughout the first three years of the settlements' existence. The Europeans thus resolved to rid themselves of this problem once and for all. To facilitate this objective, an ideological campaign was waged by colonial chroniclers, dating back to the Spanish, as they produced literature which systematically denied Kalinago humanity (a literary tradition carried through the late-seventeenth century by such authors as Jean-Baptiste du Tertre and Pere Labat). In 1626 the Anglo-French settlers joined forces to massacre the Kalinago at a place that became known as Bloody Point, allegedly to pre-empt an imminent Carib plan to expel or kill all European settlers. With the native population thus pacified, the English and French began to establish large sugar plantations which were worked by vast numbers of imported African slaves. This system created enormous wealth for the planter-colonists whilst also drastically changing the islands' demographics as black slaves soon came to outnumber Europeans by some margin.
