Between the 7th and 11th centuries, the Taíno culture developed on the island. By approximately 1000 AD, it had become dominant. At the time of Columbus' arrival, an estimated 30,000 to 60,000 Taíno Amerindians, led by the "cacique" (chief) Agüeybaná, inhabited the island. They called it "Boriken", meaning "the great land of the valiant and noble Lord". The natives lived in small villages, each led by a cacique. They subsisted by hunting and fishing, done generally by men, as well as by the women's gathering and processing of indigenous cassava root and fruit. This lasted until Columbus arrived in 1493.
