Humans have inhabited Jamaica from as early as 4000–1000 BC. Little is known of these early peoples. Another group, known as the "Redware people" after their pottery, arrived circa 600 AD, followed by the Taíno circa 800 AD, who most likely came from South America. They practised an agrarian and fishing economy, and at their height are thought to have numbered some 60,000 people, grouped into around 200 villages headed by ''caciques'' (chiefs). The south coast of Jamaica was the most populated, especially around the area now known as Old Harbour.
