At their arrival the Spaniards expected the Taíno Indians to acknowledge the sovereignty of the king of Spain by payment of gold tribute, to work and supply provisions of food and to observe Christian ways. The Taínos rebelled most notably in 1511, when several caciques (Indian leaders) conspired to oust the Spaniards. They were joined in this uprising by their traditional enemies, the Caribs. Their weapons, however, were no match against Spanish horses and firearms and the revolt was soon ended brutally by the Spanish forces of Governor Juan Ponce de León.
