Interesting to see what's going on in the Ottoman Empire - did we see the collapse of the Janissary Sultanate in the last volume, or only the beginnings?
It was covered fully in Part #168.
Either way, it's gone now, and the Ottomans are not only expanding their African borders (which reminds me of that Sotsrevist map series you did ages ago, excellent stuff that)
I'm glad someone remembers that!
Admit it, Thande... You wrote the entire update to set up that Pirates vs Ninjas joke.
Guilty as charged - and then, as always when I do this, I actually forgot to add the punchline and had to go back and edit it in

(This has happened before...)
Where's [3]?
Thanks for spotting that - I did write the line but must have left it off when copying the text from my document. Edited.
First off, great timeline and great updates. I personally enjoy the alternate technological development and the hints at the future given in the opening quotes - although I must echo OwenM's confusion as to what type of communication is being used.
Secondly, I have some questions about the Cherokee empire - specifically, relating to language.
- How many Cherokee citizens speak English as opposed to Cherokee?
- What are the etymologies of the various towns in the Empire? I've been trying to translate them, and the only ones I could fully translate were Talugisgi [meaning hardware/iron, perhaps a contraction of talugisginvnohi, railroad] and Amaganugov [a misspelled version of amaganugogv, spring].
- Was an independent Cherokee writing system developed, as in OTL, or is it written solely in Latin characters? If it is the former, who developed it?
- Why is the orthography so similar to OTL? Do the Thande Institute team "correct" Cherokee to be in line with OTL, as (IIRC) they do with English?
That's a very interesting set of questions. Basically, I don't know enough about Native American Indian (I am hedging my bets there with terminology

) languages to do this 'realistically' so what I tend to do is just use the modern OTL orthography with a few alternate anglicisation twists thrown in (mostly wearing down difficult combinations of consonants). I do this in general not only with English as you say but also with Chinese for example where I said at one point I use pinyin even though the transliteration in TTL is different, just because it would be too big a headache to keep track of.
The Cherokee population will be pretty much all bilingual by this point except perhaps in some isolated villages which only speak Cherokee, and there will be a fair few (especially the rich plantation owner types) who identify as Cherokee but aren't fluent in the language anymore and there's nothing immediately to identify them to a stranger as being different from their Carolinian neighbours, especially given that there's been some intermarriage.
As far as the place names go, these are meant to be short forms used by Carolina and other foreigners, hence why it's just Talugisgi 'iron' rather than 'iron town' or whatever (named for its iron deposits, though those are obviously not unconnected with the railways you mention). Daguvnawave is supposed to be a translation of 'Pearl River' and Nevadoheyadav, the capital, is a worn down form of a word for 'harmony'. If you have any suggestions for more place names I can always use them!
That means Belgian Maximiliaanstad in Antipodea lasted less than a decade.
It is remarkable how short-lived the colonialism of the new European powers (Belgium, Norden/Scandinavia, Naples) seems to be.
Speaking of colonialism, what was Russian Erythrea doing during the Euxine War?
Erythrea enables Russia to open another front against the Ottoman Empire
yet it is not mentioned despite the RLPC involvement in the war and successful raids on the neighboring Ottoman Arabia.
Was there some LTTW equivalent to the Gentlemen's agreement between the Russian-American Company and the Hudson Bay Company which prevented war between them during the OTL Crimean War?
Good point, it's the sort of thing that likely wouldn't be mentioned in a brief overview of the conflict like that (as you say with Alaska) but I can talk about it in a later update.
(I wasn't aware of the gentleman's agreement thing, it explains a thing or two - I always wondered why in Decades of Darkness Britain/Canada got Alaska in the Crimean War, presumably because there wasn't one in TTL).
