         | You can generally divide most of the Americas into three
         | categories: (mostly) pure indigenous ancestry, mixed ancestry
         | (Mestizo is the common term), and (mostly) European ancestry.
         | In regions where slavery was important, you also have
         | significant groups of African ancestry, mixed
         | African/indigenous ancestry, and sometimes Asian ancestry from
         | post-slavery labor importation.
         | 
         | In most of the Americas, the dominant ethnic group is mestizo.
         | Greenland is the only country where indigenous peoples are the
         | clear majority, and Guatemala is probably the only other
         | country where indigenous comes closest to being a plurality

         | Catholic colonial empires were characterized by a different
         | ethos than, say, the Protestant English. The former involved a
         | good deal of intermarriage (beginning with Cortes himself) and
         | saw what could be described as cultural transfiguration and

         | false dichotomy, as Hispanic peoples are heirs to the heritage
         | of both. And even where the heritage of non-Spanish origin is
         | concerned, here, too, it is not quite so simple. After all,
         | Cortes did not conquer Tenochtitlan with his merry band of men

         | (e.g., Tlaxcalans, Tetzcocans, Cempoalans, Huejotzingans) who
