White is a racialized classification of people generally used for those of mostly European ancestry. It is also a skin color specifier, although the definition can vary depending on context, nationality, ethnicity, point of view, appearance, etc.
Description of populations as "White" in reference to their skin color is occasionally found in Greco-Roman ethnography and other ancient or medieval sources, but these societies did not have any notion of a White race or pan-European identity. The term "White race" or "White people", defined by their light skin among other physical characteristics, entered the major European languages in the later seventeenth century, when the concept of a "unified White" achieved greater acceptance in Europe, in the context of racialized slavery and social status in the European colonies. Scholarship on race distinguishes the modern concept from pre-modern descriptions, which focused on physical complexion rather than the idea of race. Prior to the modern era, no European peoples regarded themselves as "White", but rather defined their race in terms of their ancestry, ethnicity, or nationality.
Contemporary anthropologists and other scientists, while recognizing the reality of biological variation between different human populations, regard the concept of a unified, distinguishable "White race" as a social construct with no scientific basis.
Pre-modern conceptions of whiteness
According to anthropologist Nina Jablonski:
In ancient Egypt as a whole, people were not designated by color terms ... Egyptian inscriptions and literature only rarely, for instance, mention the dark skin color of the Kushites of Upper Nubia. We know the Egyptians were not oblivious to skin color, however, because artists paid attention to it in their works of art, to the extent that the pigments at the time permitted.
The Ancient Egyptian (New Kingdom) funerary text known as the Book of Gates distinguishes "four groups" in a procession. These are the Egyptians, the Levantine and Canaanite peoples or "Asiatics", the "Nubians" and the "fair-skinned Libyans".
