Orthodox Eurasian civilization

    The Eurasian Orthodox civilization  ( Warning : This is not an article about the theology or religions, but stricly about the development of civilizations which were crystallized around them during the second millenium )    The earliest concept of Europe as a cultural sphere (instead of simply a geographic term) appeared during the  Carolingian Renaissance  of the 9th century, which reflected the territories of  Western Christianity .  However, "Europe" as a cultural term did not include the territories where the Orthodox Church or Islam represented the dominant religion until the late 19th century. ( Dr. Sanjay Kumar (2021).  A Handbook of Political Geography . K.K. Publications. p. 127.) Western historians, sociologists and political scientists often use the exact phrase : "Orthodox civilization"  since very - very long time .  See the high number Google Books results about this phrase:   https://www.google.com/search?tbm=bks&q=%22orthodox+civilization%22
