Basque people were the first to hunt right whales commercially, beginning as early as the 11th century in the Bay of Biscay. They initially sought oil, but as meat preservation technology improved, the animal was also used for food. Basque whalers reached eastern Canada by 1530 and the shores of Todos os Santos Bay (in Bahia, Brazil) by 1602. The last Basque voyages were made before the Seven Years' War (1756–1763). All attempts to revive the trade after the war failed. Basque shore whaling continued sporadically into the 19th century.
