The Basques were among the first people to catch whales commercially, as opposed to aboriginal whaling, and dominated the trade for five centuries, spreading to the far corners of the North Atlantic and even reaching the South Atlantic. The French explorer Samuel de Champlain, when writing about Basque whaling in Terranova (i.e. Newfoundland), described them as "the cleverest men at this fishing". By the early 17th century, other nations entered the trade in earnest, seeking the Basques as tutors, "for [they] were then the only people who understand whaling", lamented the English explorer Jonas Poole.
