I dunno: too many similarities to the "Gate of Worlds" map? A map for Harry Turtledove's Through Darkest Europe, a role-reversal world where the Islamic world is the first world and the Christian countries are the backwards third world states with religious terrorism issues. Basically it diverges from the 1100s on, with a more science-friendly intellectual tradition and eventually a scientific revolution arising in the Muslim world, while Christian theologians, notably Thomas Aquinas, coming down firmly on the side of investigation of the natural world being a dangerous distraction from concentrating on the next world. Turtledove in his bumbling way apparently imagines the New World as mostly Islamicized native American states and no Christians, but the advantages in length of Atlantic coastline, importance of north European sea-going trade, and abundance of wood and other supplies aren't just going to go away because Europe misses out on the scientific revolution, and it takes a while for a scientific revolution to translate into actual industrial and organizational advantages, so I'm giving Europeans some American turf. (There have been other European colonial efforts, but failed ones.) My "Maghrebi colonization of the new world" is to some extent inspired by that of greater *Morocco in Sregan's Cradle World scenario. Europe is overpopulated, struggling to modernize, and plagued with religious unrest as extreme factions in the Church (the Catholic Church is still united. Barely) react violently against rulers too friendly to Muslims or too eager to promote "scientific" thinking ("practical engineering" is OK, but distinguishing them is a matter of angels and pinheads). Divine right monarchy is the predominant mode of government, but in some places strongmen with no real dynastic claims have taken over from weak princes and monarchs. The Grand Duke of Italy is a man of that ilk (if still grooming their own son to take over) and is struggling to make Italy a modern, genuinely united nation. It's not going well, and terrorists are coming out of the woodwork. (Britain, with a long-ruling royal house with some decent propaganda, and a historical dislike of priests, is doing better, thanks in part to North Sea oil - something they have already fought one war with the Danes in determining boundaries). There's less in the way of violent outside interventions, at least: Europe lacks OTL middle East's deep pools of oil, and with it's long tradition of a military class and locally sourced soldiers rather than slave armies, Europeans aren't half bad at the war thing, when they can afford modern hardware, at least. Outside Europe, the world is a bit more peaceful than OTL: there haven't been any world wars, with the best known "big war" of the last century being the Sultanate of Delhi trying to conquer the whole subcontinent and all the minor neighboring states, under the rule of a Wazir/Prime minister turned dictator and sidelining the Sultan, a la Mussolini, but murdering millions of Tamils for the sin of being Hindu Dravidians, a la Hitler (Turtledove has to have his parallels: the dictator even started as a chicken farmer, a la Himmler). It's a generally richer world:Christian Europe and the Christian parts of the Americas (The Sunset Lands) are generally poorer or a lot poorer than the OTL areas, but the Muslim parts of what is OTL Latin America are in most cases richer, in some much richer than OTL: the middle east is first-world, Africa and India vary from richer to much richer, China is somewhat if not spectacularly richer, and Indonesia and the Philippines are quite a lot richer. Technology is a bit behind OTL, mostly in the electronics field: the universal explosion of information and hand held data cornucopias have not yet arrived.
