In 1788, John Meares explored Nootka Sound and the neighboring coasts and claimed to have bought some land from Maquinna, where he built a trading post.
Maquinna played a key role in relations between the Spanish envoy, Juan Francisco de la Bodega y Quadra, and his British counterpart, Captain George Vancouver, who negotiated the settlement of the Nootka affair and enjoyed Maquinna's hospitality at length.The title by which he is described, "Hyas Tyee", which was to find its way into the vocabulary of the Chinook Jargon, is the same as that used for king (although it simply means important chief).
One story tells how he and his people performed a masquerade for Vancouver and Bodega y Quadra in which the noble brothers acted out a pantomime of European dress and manners, improvising mock-Spanish and mock-English dialogue, all set in the customary style of the great potlatch theatre-dance culture of the Northwest Coast.
The most detailed account is told in the writings of John R. Jewitt, one of two slaves kept for several years after the crew of the ship Boston was massacred by Maquinna and his men.
A Narrative of the Adventures and Sufferings of John R. Jewitt, only survivor of the crew of the ship Boston, during a captivity of nearly three years among the savages of Nootka Sound: with an account of the manners, mode of living, and religious opinions of the natives is one of the first published glimpses into the social and cultural life of the Pacific Northwest peoples.
Maquinna required Jewitt to learn the Nuu-chah-nulth language, and told him that the ship Boston was taken in response to several depredations committed by earlier American and Spanish visitors.
