about the looks of constantine he looks mostly fine if you compare him with greeks from that period(except his nose)(and later pictures and photographs of him have him look fine if he looks like otl later in life)
is the official name <<the hellenic kingdom/kingdom of Hellas>> or <kingdom of Greece>> because i could see philhellenes and hellenes using the greek translation instead of the latin one
will you show the confederates in a more favorable ligth?from what i understand during the time of the civil war their economy was mostly comprised of slaves and they were opposed to their emancipation for economic as well as political reasons(not that slavery isnt bad but you can understand them from an economic pov)
a princess for constantine could be:
https://en.wikipedia.org/wiki/Grand_Duchess_Alexandra_Alexandrovna_of_Russia
they have 8 year difference(not that big of a deal during this time period,thougth she died at 1849)having a marriage with an orthodox princess could legitimise the monarchy even more and provide a link with russia.
could also have:
https://en.wikipedia.org/wiki/Princess_Louise_of_Prussia(4 year difference,she also seems to be tolerant enougth)(althougth a german marriage migth upset the french)
By all accounts, Prince Constantine is a relatively good looking young man and he will definitely grow into his looks as he ages, but by his father's standards' he is the "ugly" duckling of the family, especially when compared to his brother and sister.
The Greeks call their state, the Kingdom of Hellas.
The last we saw of the United States was in 1844 with the election of Henry Clay as President so things are already quite different than in OTL. Whether something like the Confederate States of America emerges in this timeline is up for debate, but slavery will definitely be an issue that the USA that will need to resolve eventually.
I've actually been considering Alexandra Alexandrovna, or rather her counterpart ITTL as a possible bride for Prince Constantine as she would have a number of things going for her. Firstly, she would be the eldest grandchild of the Russian Emperor Nicholas, and she would be the eldest child of Nicholas' son and heir, Grand Duke Alexander Nikolayevich (OTL's Alexander II), thus strengthening the ties between Russia and Greece for many years to come. A marriage between her and Constantine would also likely bring with it a sizeable dowry consisting of many tens of thousands of Pounds Sterling and many, many jewels if her sister Maria's marriage to Albert, Duke of Albany is any indication. She would also be Eastern Orthodox, which would make it easier for the Greek Government and Greek people to accept her as one of their own, while also helping her ease into her life in Greece.
There are a few drawbacks to a Constantine Alexandra match, however. Firstly, she is only ten years old as of 1852, while he is eighteen. This isn't that big of a gap in age comparatively speaking (King Leopold is a staggering 26 years older than his wife, Queen Marie), it does present a concern as the line of succession is rather short right now and Leopold isn't getting any younger or any healthier. By the time Alexandra Alexandrovna is of age to marry (she would be 16 in 1858) Leopold would be nearing his 68th birthday and I don't know if he would be willing to wait that long to get a wife for Constantine, not to mention an heir for his heir. There is also another issue, namely the matter of their consanguinity with one another as Constantine and Alexandra would be second cousins with each other through their shared descent from Tsar Paul of Russia. I know that marriages between first cousins is usually shunned in the Orthodox Church, but I'm not sure about marriages between second cousins. Finally, a Russian bride for Prince Constantine might sour relations between Greece and Britain given the general animosity and Russophobia in Westminster at this time. Given his precarious situation, Leopold would definitely not want to upset any of the Powers, particularly Britain if he can avoid doing so.
TTL's Princess Louise of Prussia would also be a good choice for Prince Constantine. While she wouldn't provide as valuable a relationship for Greece; Prussia has a completely different sphere of influence and interests compared to Russia, it would still provide for a strong relationship between Prussia and Greece that could have some interesting effects going forward. It also wouldn't hurt Greece's relationship with Britain either which is something Leopold would definitely want to consider with any match. Princess Louise would also be about 4 years older than Grand Duchess Alexandra Alexandrovna, meaning a marriage between her and Constantine could take place earlier around 1854/1855 which isn't too far off currently.
Either Grand Duchess Alexandra or one of her father’s cousins (the two youngest daughters of
https://en.wikipedia.org/wiki/Grand_Duke_Michael_Pavlovich_of_Russia would have the right age I& they survived).
Other relatives of the Zar available are
https://en.wikipedia.org/wiki/Princess_Maria_Maximilianovna_of_Leuchtenberg (niece of Alexander II) or
https://en.wikipedia.org/wiki/Grand_Duchess_Alexandra_Petrovna (she was a Lutheran great granddaughter of Paul I who was raised in Russia)
Michael Pavlovich's daughters are certainly an option and would help strengthen the connection to Russia for Greece, but they do have a particularly big consanguinity problem as they would be second cousins, twice over via their descent from Tsar Paul of Russia and their descent from King Frederick I of Württemberg. Outside of that, Anna Mikhailovna would probably be a good choice as she would be the same age as Constantine, meaning they could be married immediately and it wouldn't irritate Britain to the same degree as a marriage to Alexandra Alexandrovna would, although I'm sure the British still wouldn't like it too much.
Princess Maria Maximilianovna of Leuchtenberg is another good option as she is the granddaughter of the Tsar and via her grandfather Eugène de Beauharnais, she has a connection to Napoleon II of France, albeit a distant one. The latter may work against her however, as Leopold was not very fond of the House of Bonaparte. Outside of that I can't find anything wrong with Maria Maximilianovna aside from her being a little young currently, she would be only 11 in 1852 meaning her marriage with Constantine couldn't happen until 1857 at the earliest.
Based on my understanding of the Orthodox Church's views on consanguineous marriages, I don't think a marriage between Grand Duchess Alexandra or Prince Constantine would be possible as they are first cousins via their shared descent from Grand Duchess Catherine Pavlona of Württemberg. Apart from that she seems like she would be a good candidate as well, being 14 in 1852 and she would provide another connection to Russia. Her strong support for charity, simple nature, and earnest devotion to the church would also help ingratiate her to the people of Greece as well.
That's a very interesting take on the Ottoman Empire that I hadn't heard before, but it does make some sense. Without a cohesive "Ottoman" identity that could unite the many different ethnic and religious groups together, the Ottoman Empire was bound to experience rebellions and revolts until the empire collapsed or the minorities were killed/driven out. This has also provided me with a lot of insight into Greek education during this period which will certainly be helpful in the future.
honestly greece having crete will benefit it immensely, furthermore crete benefits a lot by not having to revolt against the ottomans.and its not really that big of a blessing considering that the situation was settled diplomatically for the most part
https://en.wikipedia.org/wiki/Ottoman_Crete#Rebellions_against_Ottoman_rule
there is also the possibility that muslim cretans will be considered greek in the future(they speak a greek dialect)with the rise of literacy(probably by the lower classes the only difference they have is religion)
Furthermore seeing the success that greece had the bulgarians ,serbians,arabians and other groups will agitate more for freedom and egypt is not going to give up.
Russia will also probably help a lot of orthodox christian groups for their own interests
I definitely agree, Greece having Crete in 1830 as opposed to 1908 is a huge gain for them over OTL as it provides a much needed boost in population and resources that they didn't have in OTL at this time, the ports of Iraklion, Chania, and Rethymno among others also strengthen Greece's grip of the Aegean benefiting Greece both militarily and commercially. Many Muslim Cretans left the island after the Greek War of Independence fearing retribution and discrimination, but many also choose to stay on Crete as it was their home and all they had ever known. Aside from a few outliers, by 1852, most Cretan Muslims are considered as Greek as any other Greek on the island of Crete; they speak Greek, they write in Greek, they have Greek names, they wear Greek clothing, many even serve in the Greek military and the Greek government, although they don't hold any particularly high public offices.
The success Greece has experienced thus far ITTL is definitely being looked at by many of the ethnic groups in the Ottoman Empire and I would definitely expect the Russians to interfere where they can.
