Oh dear. While Turks take a well won victory now and get some breathing room, this could lead to a stronger Russia. Also it looks like France and Italy might be getting together with the Tsar in the near term to discuss how to put the 'Porte' in place.
The Ottoman sickman has gotten out of bed, but now he is in the ring and facing far more potent foes.
True. On the other hand, the Ottomans now have a good reason to industrialize and become stronger due to having more overt enemies ITTL. Britain would also want a powerful bulwark against Russian expansion in the Balkans, though this will put them in conflict with Constantinople hearing the pleas of far-flung sultanates. France and Italy might conspire together with the Tsar, but both of them will have to sort out their own claims over the world first, some of them overlapping a great deal (looking at you, Tunisia
).
There's going to be a conflict of interest among the European Powers in the coming years, and it will force many of them to take unexpected paths.
So the Europeans identify the Ottomans as an anti-colonial force? This could be problematic for the Ottomans in the long run as you seem to suggest, but there is no doubt that surviving Muslim polities in East Asia and further afield are going to be inspired by the Ottoman victory. I wonder if in the long run it will be seen as Tsushima was in Asia in OTL...
Well, not necessarily anti-colonial but certainly pro-sultanate. Abu Bakar's visit and the voyage of the Acehnese emissaries have already shown Europe that some polities are still powerful enough to chart their own course even in the face of colonialism. Should they now visit the Ottomans, there will be a good chance that Sultan Abdul Hamid might hear their pleas and actually act on them, a fact that has Netherlands worried sick.
In the long-run, the Ottoman victory might actually be taken somewhat differently in certain world regions. In North Africa and the East Indies, it marked Islam's return to relevancy on the world stage. For Sub-Saharan Africa and East Asia, it's just another Western Power rising to dominate everyone else. Also, I should note that there are still many independent sultanates out there in the world during this time period, and many of them would want to be the first to receive Ottoman aid or protection. Constantinople might find itself facing a Noah's Deluge of pleas in the next few years and not knowing where to start!
A resurgent Ottoman Empire. Nice.
While you're at it, how about butterflying to have Qing China beat France in 1885? The OTL Sino-French War did see some significant Chinese victories in Taiwan and Vietnam, much to the embarrassment of the French, so maybe you could exploit the potential butterflies there.
After that, maybe have Empress Dowager Cixi die before 1890, so that Emperor Guangxu would be more in charge, and crucial funds needed for the Beiyang Navy's ammunition would not be siphoned off to build her Summer Palace to celebrate her would-be 60th birthday in 1894.
This would at least put China on a stalemate with Japan when war breaks out a decade later. Japan would still have the upper hand due to a headstart in Westernization and more disciplined and less corrupt, but China would still manage to hold out on its own, leading to a European power (not Russia ITL it would seem) intervening for a negotiated settlement. Though mainly Tokyo frowning and Beijing chuffed to bits.
Possible, though I might need to research some more to work out the details. As far as I know, the Sino-French War was one war that could
really go either way, especially with the British closing their Eastern ports to French shipping and all. Even a stalemate alone can change European views of China in the short-run.
As for the country itself, I'm
still vacillating on what to do with Cixi and Guangxu. While it's true that having the Empress butterflied would be better overall for China, having Guangxu reign still wouldn't solve the enormous regionalism that plagued the Empire, or the rivalry between the army and navy, which was already regionalist in itself to begin with. Perhaps Guangxu could unify the navy into a single fighting fleet, but doing the same to the army would just open a Pandora's Box that could end the empire early. And above all, there is the Qing court to consider.
As for Japan, they will play a role both in East Asia and in Southeast Asia. However, as with Europe, Tokyo ITTL might find itself walking down unexpected paths.
And if you're ambitious, have a 3-way Battle Royale in the Russo-Sino-Japanese War of 1904-05. With a resurgent China and a desperate Japan both eager to find a punching bag to flex their newfound muscles. Add in the Ottomans (with their Navy in SE Asia by now intercepting the Russian Baltic Fleet) for a 4-way fight.
Of course, just as a resurgent Ottoman Empire help boost Muslim pride in SE Asia, a resurgent China would have the same effect on the growing Chinese immigrant community in SE Asia, including Sarawak. The Brookes would have a lot of work to do to keep both communities loyal.
Ahh... this will be when things get a little screwy. Both China and the Ottomans will try and influence the East Indies to their design, but they would also face several stumbling blocks both sides never really expected.
For one, the Ottomans might come out more powerful ITTL, but I don't think London and Amsterdam would approve of them stationing their fleet out in the East Indies. In fact, I wonder if Great Britain and the Netherlands would try to misdirect the Ottomans to focus more on North Africa and the Sahara rather than the East. Barring the slave trade, containment in Africa could be preferable than influence in Sumatra.
For another, Southeast Asia is a region that has seen Chinese, Indian and Arabian migration for centuries. Just look at the Lanfang Republic. The cultural mixing alone is enough to raise eyebrows in Kostantiniyye, and the arrival of the British and the Dutch had also exposed new ideas to the native populace. By this point, Chinese revival societies would already start establishing themselves in Penang and Singapore, clamoring for political reform back home as much as economic reform. The Malays might be more amendable to Ottoman aid, but the more traditional folks would want the traditional Hindu-Bhuddist
Adat to be enshrined and protected.
As for Sarawak, with it's greater intercultural mixing, the less said the better...
