67.) Islamic Germany - in which an earlier spread of Islam to North Central Asia led to Europe being overrun not only by Mongol-equivalents, but Islamic ones to boot. Although in the end the Christian states of Iberia, the British Isles, and Italy managed to break away from the Islamic-Mongol Yoke, and later liberate southern France, Northern Europe remained under Islamic rule, and over times became Islamicized, although the Sultanate of Mainz still runs about 12% Christian nowadays.
The world is dominated by Islamic powers, although the underdog but highly capitalistic Christian states have done a rather better job of imitating Islamic modernity than the Muslims of OTL have in going the other way around. Although the Germans and their North African and Scandinavian pirate allies challenged the Christians for mastery in the Atlantic, most of the Americas are Christian, colonized by the powerful British-Castilian monarchy and their Portuguese and South French allies. (There were a _number_ of colonial efforts by the Germans in the Americas, a few of which still exist today. But they did get something of a last laugh when they helped most of the BC colonies in the Americas to break away from Londres in the 19th century).
Anglo-Spanish Greater Mexico is the most important of the American states: if a bit backwards by the standards of the great Islamic powers, it is still a major industrial power. Other major states include Germany itself (includes OTL Bohemia, Poland, the Low Countries, and northern France), Islamic Rus (roughly OTL USSR less east Siberia, central Asia, and the South Caucuses), The Persian Union, Mongolia-Korea, and the sprawling mass of the “slaver state” in Africa, an Swahili-dominated dictatorship looked upon with considerable distaste by other important states. India is politically fragmented between Hindu, Muslim, and mixed states. The Balkans are a mix of small Muslim and Christian states, while Italy is a hard-headed mercantile oligarchy that has been perfectly willing to ally or kowtow to Muslim states when needed, but has always kept the fortifications on its Alpine frontiers well equipped and manned.
There have been two major wars in the last century: the first saw the collapse of the Khanate of Ind and the Turkish Empire of Rum, and the reemergence of Persia as a major power, while the second, following the breakup of the Anglo-Castilian monarchy, led to the expulsion of Russia from the Balkans and the replacement of the Khanate with a Behnamist “people’s state” (a republic, more or less, rather than the Communist dictatorship that would imply OTL), the collapse of colonial rule in much of still-Buddhist and Taoist continental East Asia and the reemergence of south China and (mostly Islamic) Nippon as independent states, the development of the first Corpuscular Bomb by the Germans (too late to use in the war) and the emergence of Greater Mexico as an important state on the world stage, and the end of the Iberian dictatorship. (Reunification with Britain is still being debated).
The Christian states tend to be oligarchic or monarchial, and although his Imperial Majesty George Arbusto of Greater Mexico is a constitutional monarch, he still has some real power. (Mexico is linguistically complicated: although “Spanglish” is the normal means of communication, Castilian is something of a prestige language, some communities are almost monolingual English, and then there are the Native Americans). It’s generally a peaceful world, although Hindu-Islamic conflicts in India, squabbles between the states of balkanized North America, and hostility between a modernizing (if not yet great-power) South China and the Mongol-Korean Empire which holds much of what it considers its historical soil still make for occasional overheated headlines - and then there’s that nastily racially and religiously divided African colossus.
Technology is roughly OTL, and it is an economically somewhat more leftist but socially more conservative world than ours: in much of the Islamic world women now have the vote, but their social roles are still on the order of women in OTL 1950s (and with much more modest clothes). It is a fairly tolerant one, Muslims and Christians getting along roughly as well as Protestants and Catholics in the late 19th century, there is little discrimination against people with a black skin, and Mexico has even allowed Jewish immigrants since the 1960s. (Alas, Eastern and Indian “Paganism” are still very much looked down upon, and both Christians and Muslims send a lot of missionaries to mainland SE Asia). Given how much of the Islamic world is located on ecologically fragile land, global warming threats are being taken rather seriously.
