Oceania
Oceania is the smallest continent, spanning the Pacific Ocean.
Oceania is a geographical region including Australasia, Melanesia, Micronesia, and Polynesia. It is also described as a continent, with mainland Australia regarded as its continental landmass. It is the smallest and second-least populated continental land area after Antarctica, and is home to Earth’s third-largest remaining area of tropical rainforest, which covers much of the island of New Guinea.

Lore & Background
Oceania was first explored by Europeans from the 16th century onward. Spanish and Dutch explorers followed, then British and French. On his first voyage in the 18th century, James Cook went to Tahiti and followed the east coast of Australia for the first time. The arrival of European settlers in subsequent centuries resulted in a significant alteration in the social and political landscape of Oceania. The Pacific theatre saw major action during the First and Second World Wars. The rock art of Aboriginal Australians is the longest continuously practiced artistic tradition in the world. Most Oceanian countries are parliamentary democracies, with tourism serving as a large source of income for the Pacific island nations. Definitions of Oceania vary; the broadest definition encompasses the islands between mainland Asia and the Americas. The culture of the people who lived on these islands was often distinct from that of Asia and pre-Columbian America.
Reader's Guide
Oceania's significance lies in its unique geographical and cultural identity as a region defined by the ocean rather than a contiguous landmass. It is the smallest continent and the second-least populated, yet it contains a diverse mix of economies, from highly developed ones like Australia and New Zealand to less developed ones like Kiribati and Papua New Guinea. The Pacific theatre saw major action during both World Wars. The United Nations uses a geopolitical definition of Oceania that includes four subregions: Australasia, Melanesia, Micronesia, and Polynesia, and categorizes it as one of the major continental divisions of the world. Oceania's legacy includes the longest continuously practiced artistic tradition in the world—the rock art of Aboriginal Australians—and a predominance of parliamentary democracies among its nations.
