In what direction would Europe have developed if the Roman Empire had not accepted Christianity as its official religion. Is it likely that we still would see the development of a feeling of belonging to a common culture? Since this would also butterfly Islam, I assume that Southern Europe would continue to have closer ties to the areas south of the Mediterranean than to Northern Europe (although this would also be likely in a scenario with a POD that only butterflied Islam, not a Christian Roman Empire). Would one still see the development of several smaller kingdoms fighting each other, marrying each other and so on? Would it mean an earlier or a delayed industrialization or would religion not influence this in any way? If it would delay industrialization, would some other part of the world industrialize first? Is it at all possible to say something about this? Was the world "predestined" to industrialize sooner or later anyway, due to gradual development of technologies)?
