One defenition of Civilizations as per historian Arnold Toynbee (I am quoting from Wikipedia page for his work "The Study of History") is as follows: "The 19 major civilizations, as Toynbee sees them, are: Egyptian, Andean, Sinic, Minoan, Sumerian, Mayan, Indic, Hittite, Hellenic, Western, Orthodox Christian (Russia), Far Eastern, Orthodox Christian (main body), Persian, Arabic, Hindu, Mexican, Yucatec, and Babylonic. There are four "abortive civilizations" (Abortive Far Western Christian, Abortive Far Eastern Christian, Abortive Scandinavian, Abortive Syriac) and five "arrested civilizations" (Polynesian, Eskimo, Nomadic, Ottoman, Spartan), for a total of 28."
