Traditionally, archaeologists have estimated that the earliest settlers arrived in successive waves in outrigger canoes from Southern Kalimantan, Indonesia, possibly throughout the period between 350 BCE and 550 CE, while others are cautious about dates earlier than 250 CE. In either case, these dates make Madagascar one of the latest major landmass on Earth to be settled by humans, predating the settlement of Iceland and New Zealand. It is proposed that Ma'anyan people were brought as laborers and slaves by Malay and Javanese people in their trading fleets to Madagascar.
