I'm not sure if they lagged so far behind either.
Old Gorganj/Urgench was devastated by the Mongols but it was rebuilt by the Turks. Then that was destroyed much more thoroughly by Timur-- but also, the Amu Darya shifted away from the old city, so there was no point rebuilding. After this Khiva City took its place, and a
new Urgench was founded much later. But, this TL doesn't have to have a Timur. Or it might have one, but Gorganj doesn't have to rebel against him and get razed to the ground. But even then, the river shifting course will doom the city in the long term, its population will just move to a new site and build a new city.
I
guess Merv/Mary fell to the wayside permanently, it was not rebuilt or replaced by some other nearby city. But it looks like rebuilding was done throughout Khwarezm to the extent which Turkmen raiding allowed.
Sure, this still leaves Khwarezm as a very small territory, probably a lot of damage to irrigation works that later governments were too buys fighting to repair. Khivan Khwarezm played second fiddle to Bukharan Transoxiana and Ferghana. But was Khwarezm itself as proportionally important to the Khwarezm-Shahs as their other possessions? The Khwarezmshahs were Turks, so the strength of their army didn't entirely depend on the amount of land under a plow-- they could draw on pastoral populations too. Khwarezm might offer a potent image of paradise lost but we might be overrating its performance before the Mongols and underrating its performance after.
Don't exist yet
and there's no guarantee that they will. They're just Flemish, Brabantines, Frisians, and others for the time being. And, there's no guarantee that whoever does mess around in Asia on their behalf does it in the same way as the OTL Dutch.
The Latins had better be careful though-- if the Ethiopian kings still claim Solomonic ancestry and unswerving adherence to Coptic Christianity, they might just claim the crown of Egypt should the opportunity ever arise-- a serious civil war in Egypt for example.
I can see the Latins running into a similar problem in Nubia-- this land has very little experience of direct Islamic rule aside from whatever attention Kanz ad-Dawla can spare from holding down Upper Egypt. After that there may still be rogue tribes of Arab and African Muslim cowherds, but aside from that it's a nearly 100% Coptic society. If the old Makurian and Alodian kingdoms are allowed to remain, then... well, they'll keep to themselves. They better watch out for climactic shifts or those cowherds might successfully take over. But if the Latins come in (maybe chasing Kanz ad Dawla or his successors) and stay, the Nubians may not have much patience for Latins awarding themselves fiefs if they don't go into the desert and make themselves useful.
Although that make be easier said than done-- the Islamization of present day Chad, either through the Sao city states or the Kanem Empire, isn't something Europe can really stop (Trans-Saharan trade will likely only deepen in economic and religious significance). And Chad is connected by trade and pastoral routes to Darfur, and then on to Nubia... the Red Sea and the internal Muslim population might be high on Egypt's list of concerns but really it's the Sahara that will deliver steady, incessant pinpricks of raids and rebellions, each with a chance of evolving into something far more dangerous (Islam will supply organization to confederations of Shuwa/Baggara Arabs, Toubou, and other peoples, and a focus/justification for their raids-- it will become the basis for small but bothersome polities like Wadai and Darfur). Nor do the Egyptians have any easy way of policing the Sahara before... well, whatever the French did. I'll have to read this book-- looks like it was a very case by case thing, and never quite secure until trucks, machine guns, and planes entered the scene.
In The Conquest of the Sahara, Douglas Porch tells the story of France's struggle to explore and dominate the great African desert at the turn of the century.Focusing on the conquest of the Ahaggar Tuareg, a Berber people living in a mountain area in central Sahara, he goes on to describe the...
