(sorry for my bad england beforehand) I'm making a modern day ww1 central powers victory scenario. I'm using Ulyanovsk's 1914 map as base map (full version here, thanks him/her very much for sharing it with me). Borders, colors is not final yet but its pretty much will remain similar. The little lore is; most of the events before and during WW1 is happened same way in OTL. Russian civil war happened, ottomans got invaded through iraq and palestine etc. Finally, central powers won the war by a late date victory (like in 1918, spring offensive or something like that). I haven't finalized the lore yet, so questions like "was there a french civil war and regime change after the war?", they are not clear yet. This because i mainly focused on modern day borders rather than a story/lore writing. There are events/wars like for bulgarian and hungarian ones but i haven't finalized their dates, details for the reason I stated.
So, for some questions and its answers:
-What happened to Russia, who won the civil war?
+Whites. It wasn't a random decision tho, Neither Allies or Germans like the bolsheviks and wanted a communist state. From both sides help? and without the eastern europe falls into bolshevik's hands after Germany's surrender like OTL, Whites won the civil war.
-What happened to A-H?
+A-H didn't dissolved after the war, it happened after few years-decades. By that time they made significant progress towards federalization, but Hungarians didn't like that. They didn't wanted to share the crown with a 3rd (Croatia) and give away-give autonomous to minority areas of lands they control. Finally, the Hungary left the federation with it's big hungary borders. As you can imagine, they weren't that gentle towards to minorities, so with minority protests/insurgencies and the other countries involvement, the big hungary downgraded to in the map borders. New states were established in regions where there was no absolute majority, for example Banat and Transylvania. Especially Germans wanted this too, with that way they can influence the balkans more easily.
For Galicia and Lodomeria, Germans wanted it stayed as a individual state. But long time irredentism, clashes inside country from both sides and weakening German influence over the related countries eventually led to dissolution and annexation of the country's lands.
About Austria, after the dissolution of federation, weakening it's influence over member countries and the Germany's and the vast majority of public's desire to unite with Germany led to unite with Germany.
-What happened to Ottomans, why the long Turkey?
+ Ottomans didn't dissolved after the war, in fact, they survived more than A-H. This because is victory in the war and German help to tidy up the country after the war. One more factor was oil too. After the war, with the results of Arab revolt and last period Turkish nationalist government in Ottoman Empire, they somewhat gave some autonomy to minorities, especially Arabs, and the empire started liberalise. Long story short, with the (ofc) influence of great powers (mainly britain, france and u.s.) and disagreement between Turkish and other ethnicities, Turks supreme and repressive attitude towards minorities and general nationalist and liberalist trends on the world eventually led to dissolution of Ottoman Empire. However the dissolution happened with more of agreement based than a military conflict one. Turks got the strategic and holdable areas for themselves.
Btw about armenia and azerbaijan, after the ww1 ottomans annexed both of them. Its not a suprise, the Ottoman government then was Turkic nationalist and in favour of that. The one thing that always confuse me is, in most WW1 central powers win scenarios Ottomans or azerbaijan doesnt get the south azerbaijan. In OTL, they captured the south azerbaijan, so i dont know why people doesnt give it to them, probably because of lack of knowledge (im not judging or mocking it).
-Bulgaria, balkans
+After ww1, bulgaria got the lands they promised before. They basically treated minorities in that lands repressive. Same story as Hungary, eventually they evolved to current map borders. About albania, first they got albanian lands from bulgaria, after that there was Albanian insurgency in Serbia, Kosova. After some clashes, with the supervision of great powers which mainly is germany, they got a agreement which defines to current map borders of two nations.
-What about outside of Europe?
+Nothing much interesting about border changes. Japan fights with China same like OTL and lost it. North and South America's borders is nearly same as OTL, maybe the 100% same. Africa would be mostly same with even exchange of colonies (im talking about modern country border changes in this paragraph). Aside from middle east, central asia, asia is would be mostly same as OTL too.
Cuz of its WIP, i still will change and renew some borders and colors. Like in central asia, you see its the OTL borders, which will i change it. Western border of germany, i drew it blindly (aimed for briey basin and western slopes but yeah, i definitely renew it). Middle east borders, iraq, palestine and hijaz mainly, also add other countries to there too. Don and kuban republic borders. Slovakia and transylvania needs some little touches too.
Btw with the few exceptions above, I placed great emphasis on border accuracy (never heard 'placing emphasis' btw, thx to google translate). So you can ask me questions and recommend advices like: "why this border is 2 pixel left" or "would'nt it better to use 1834 border instead of 1835". I am and will looking forward for even smallest graphic changes.
Im currently on mobile, i will convert this project with some tool like QGIS or another one to a nice looking map. Also planning to expand and detailing the lore alongside the map changes. Especially as i write, i tired so english translations may be bad and lazy. Maybe i edit it later.
