Oceania 30 BCE
A new phase of Polynesian expansion in the Pacific is occurring.
What is happening in Oceania in 30BCE
In Australia, the long dry spell is giving way again to a wetter climate, much like that of the present day. This period sees the emergence of long-distance trade routes, which in turn stimulates the quarrying and manufacture of stones and stone artifacts on a proto-industrial scale in some favored locations, for distribution over a wide area.
In Polynesia, there is a new phase of outward expansion into the Pacific: Tahiti and the Society Islands have been colonized from Tonga and Samoa, and the Marquesa Islands have also been settled, from Samoa. The motivations for such long colonizing voyages are largely to be found in the immense, semi-divine prestige attached to founders of new settlements; in a very status-conscious society such as the Polynesian, this was one of the few ways in which a junior member of a leading clan could found a high status clan of his own.
