the british explorer captain james cook who 'discovered' Hawai'i (although you can't discover something that was already discovered), tried calling it that in an effort to 'own' discovery of it. However, you can't rename a country that already has a name so Hawai'i remained Hawai'i. It is technically only referred to as the sandwich islands, not renamed that. captain cook tried naming Hawai'i the sandwich isles (islands) after his sponsor who was the earl of sandwich.

When the Hawaiian islands were discovered by Captain Cook, he named them The Sandwich Islands after Earl Sandwich.
