The use of dragon boats for racing and dragons are believed by modern scholars, sinologists and anthropologists to have originated in southern central China more than 2,500 years ago, along the banks of such iconic rivers as the Chang Jiang, also known as Yangtze (that is, during the same era when the games of ancient Greece were being established at Olympia). Dragon boat racing as the basis for annual water rituals and festival celebrations, and for the traditional veneration of the Asian dragon water deity, has been practiced continuously since this period. The celebration is an important part of ancient agricultural Chinese society, celebrating the summer harvest. They first used a "dragon boat" to save a local scholar from drowning in the river and went to save his life. They now honour this feat on (or around) the 5/5 every year (Lunar Calendar).
Outrigger canoes were originally developed by the Austronesian speaking peoples of the islands of Southeast Asia for sea travel, and were used to transport these peoples eastward through to Polynesia and New Zealand during the Austronesian migration period. Even today, it is exclusively among the Austronesian groups (Malay, Micronesian, Melanesian and Polynesian peoples) that outrigger canoes are used.
