A citizen of
India, also known by some Westerners as "East Indian", though citizens of the East Indies are not uniformly Indian in ethnicity.
Christopher Columbus, suffering from his era's version of jet lag and brain cramp, called the Caribbean indigenous peoples (e.g. the Carib) he found "Indians" as well, though few modern-day "West Indians" are descended from those Indians.
Related to this, the name stuck to refer to people further north, a.k.a. Natives or Native Americans, though a Paiute, an Algonquin, and a Lumbee may have little more in common than the fallout of centuries of outside oppression that may still reside in their psychic DNA.
