Before the arrival of the Spanish, San Sombrèro was said to inhabited by several "Amer-Indian" ethnic groups, called the "Ciboney" (Siboney) (Nomadic hunter-gatherers), "Taino" (who lived on seafood), "Puorcina" (who practiced simple agriculture) and the most dominant "Guanajaxo" (they just stole from everyone else). But there was a tribe that existed before called the "Bollivquar", fierce warriors who regarded themselves as a very complex and advanced society, which is said to be odd because they "never quite" mastered fire, irrigation or star jumps. But they learnt how to farm tobacco, which to this day still remains a part of the Bollivquar diet, explaining their stunted growth. Note that their inability to light a fire made it harder to take up smoking.
