The Taíno arrived from Hispaniola sometime in the 3rd century A.D. When Columbus arrived, they were the dominant culture in Cuba, having an estimated population of 150,000. It is unknown when or how the Guanahatabey arrived in Cuba, having both a different language and culture than the Taíno; it is inferred that they were a relict population of pre-Taíno settlers of the Greater Antilles.
