Our quasi-polity are often embedded within larger-scale cultural groupings of polities or quasi-polities. These are sometimes referred to as 'civilizations'. For example, medieval European kingdoms were part of Latin Christendom. During the periods of disunity in China, warring states there, nevertheless, belonged to the same Chinese cultural sphere. Archaeologists often use 'archaeological traditions' to denote such large-scale cultural entities (for example, Peregrine's Atlas of Cultural Evolution). Note, 'supracultural entity' refers to cultural interdependence, and is distinct from a political confederation or alliance, which should be coded under 'supra-polity relations.'
