Taking influences from B_Munro’s Caliphate of Rum and Years of Rice and Salt maps (and a few names for Chinese American colonies from his other maps), and based on the US becomes the Middle East thread by Tsochar on AH.com.
Somewhere in northern Mongolia, a child is born dead. While a tragedy for the family, the wider world does not notice. But this death would have far-reaching consequences that nobody could see. For in other worlds, this child would have been Temujin, the great nomad warlord who would forge the largest empire in human history. In this world, other warlords would try to unite the Mongols, but they would not be as successful as Temujin would have been. Now, history would go on without the Mongol Empire.
Perhaps the greatest beneficiary of Temujin’s absence is the Islamic world. In other worlds, Mongol hordes ravaged the Islamic world, destroying ancient cities and killing millions. Here, the Islamic world continued to ascend. Constantinople, and the Eastern Roman Empire, would fall in the 1300s. The Moors successfully secured Iberia from Christian attempts to retake the peninsula. Muslim slavers penetrated deeper and deeper into Africa, and trade with the East increased. Even Rome, center of the Catholic Church, would fall to Islamic invaders in the 1500s, the height of Islamic power. Of course, the Islamic powers continued to war amongst themselves, and could never take a more united Europe. The Chinese initially benefited from Temujin’s absence, but several dynastic wars prevented them from having unchallenged progress above the entire world.
Assaulted from all sides, Christendom sought to allies elsewhere and a way to escape from a continent they felt would fall to Islamic conquest at any moment. The discovery of the Atlantean continents by Norse sailors was initially regarded as a curiosity, but as independent Moorish and Chinese discoveries revealed great continents to the far West, it was the Christian powers which were the most ardent colonizers. Missionaries spread out throughout North and South Atlantis, converting natives and even abandoned Chinese settler colonies to the far west. The nations of Europe, especially the Dutch, English, French and Teutons, sent as many of their sons to North Atlantis as possible. European expeditions and missionaries even spread out throughout the Far East, converting the Happonese to Christianity. South Atlantis and Africa on the other hand, were secured by the Islamic powers, seeking commodities in the lands they believed to be more prosperous.
History happens, and by the 20th century the world is divided as much along ideological lines as along religious. The dominant power is the Federated States of Eurasia, a descendant of the Turkish empires which dominated the Near East. It is the world’s greatest power after the collapse of the Workers’ Union, a Euro-Atlantean syndicalist superpower which collapsed under its own weight only a few decades ago. Founded in a democratic revolution sometime in the 17th century, the Federation leads an alliance of democratic states and seeks to free the world from tyranny. However, many of the Federation’s allies regard this lofty goal as a fig leaf for imperialism, and conspiracies abound regarding Istanbul’s attempts to create a world empire centered on itself. Its allies in North Atlantis are very controversial: the Atlantean Republic is under military rule to “ensure secular law,” and the Republic of New Zion has many disputes with its Christian neighbors and is frequently accused of favoring Jews over all others within its borders.
Challenging the Federation’s vision of a democratic, secular world are the other blocs. The League for Traditional Values sees the Federation as the leader of an apostate bloc and seeks to place the Islamic world under theocratic rule. The Italian-based Caliphate of Rum also has dreams of recreating the old Roman Empire, only under Islamic rule. Then there are the United Technocracies of Man, based out of the former Kingdom of Persia. Believing current and former governmental systems to be inefficient, the United Technocracies seeks to place the world under the rule of djinn, artificially intelligent machine constructs.
Outside of the Islamic world, there are two other blocs which seek to gain power and prestige in the world. The Nanjing Pact is a loose collection of non-Abrahamic powers centered on the Confucian Republic of China, an authoritarian state ruled by a byzantine bureaucracy and operating on ostensibly Confucian values. Within the Nanjing Pact is the Indian Confederacy, which seeks to create a Hindu theocracy throughout the subcontinent, and the Republic of Meichi, whose retention of native polytheism has made it a target of Christian terrorism. The former Workers’ Republic, centered on the Vinlandish Federation, also wishes to regain its lost prestige and regards the Federation as a “frenemy.”
Then there are the Christian powers of Europe and North Atlantis. Mostly theocracies, the Christian states seek a “global crusade” against the “heretics,” starting with the Islamic powers. The states of Holy Teutonia and Happon have mixed their theocratic ambitions with territorial ones. The Christian Republic of Tihan, which overthrew the old Federation-backed Tihanese Kingdom decades ago, also wishes death upon the “Great Satan” of Istanbul, and has ironically gained local power after the destruction of the Arqanzan Republic at the hands of the Federation.
