This article discusses the history of whaling from prehistoric times up to the commencement of the International Whaling Commission (IWC) moratorium on commercial whaling in 1986. Whaling has been an important subsistence and economic activity in multiple regions throughout human history. Commercial whaling dramatically reduced in importance during the 19th century due to the development of alternatives to whale oil for lighting, and the collapse in whale populations. Nevertheless, some nations continue to hunt whales even today. Early history Humans have engaged in whaling since prehistoric times. Early depictions of whaling at the Neolithic Bangudae site in Korea, unearthed by researchers from Kyungpook National University, may date back to 6000BCE. The University of Alaska Fairbanks has described evidence for whaling at least as early as circa 1000BCE. The oldest known method of catching cetaceans is dolphin drive hunting, in which a number of small boats are positioned between the animal and the open sea and the animals are herded towards shore in an attempt to beach them. This method is still used for smaller species such as pilot whales, beluga whales, porpoises and narwhals, as described in A Pattern of Islands, a memoir published by British administrator Arthur Grimble in 1952. Another early method used a drogue (a semi-floating object) such as a wooden drum or an inflated sealskin tied to an arrow or a harpoon. Once the missile had been shot into a whale's body, the buoyancy and drag from the drogue would eventually cause the whale to tire, allowing it to be approached and killed. Cultures that practiced whaling with drogues included the Ainu, Inuit, Native Americans, and the Basque people of the Bay of Biscay. The Bangudae petroglyphs show sperm whales, humpback whales and North Pacific right whales surrounded by boats, and suggest that drogues, harpoons and lines were being used to kill small whales as early as 6000BCE. Cetacean bones of the same period were also found in the area, reflecting the importance of whales in the diet of prehistoric coastal people. Whale bones recovered near the Strait of Gibraltar raise the possibility that whales were hunted in the Mediterranean Sea by ancient Rome Whaling history by region North America New England Beginning in the late colonial period, the United States grew to become the preeminent whaling nation in the world by the 1830s. American whaling's origins were in New York and New England, including Cape
