Lets say the Ottomans collapse due to a dynasty extinction of the house of Osman in the chaos of 1808 with all the assasinations leading to Mahmud II being killed, leaving no surviving successor which leads to a collapse of central authority.
If this happened what new states would be created or expanded?
How would the Turks reorganise themselves and who would rule them?
In the Balkans you had independant Serbia and Danubian principalities and you had regional Ayans who had large amounts of power.
You had strong regional governors like the pashaliks of Albania
https://en.wikipedia.org/wiki/Albanian_Pashaliks who could have created their own states in the region, maybe they would try to intergrate into the local culture.
You also had rising nationalism in Greece mainly but to some extent in the rest of the Balkans.
You also had the Armenians and Assyrians who may want their own state.
In Iraq you had the Mamluks in power who could have created their own state.
In Kurdistan you had a bunch of small states, who maybe could have federated for self defence.
In Egypt you had the Alis who would go on to take a lot of land.
In central Arabia you had the first Saudi state who recently captured Mecca.
In Persia who had a long history of wars with the Ottomans, maybe they would try to take the Shia parts of Iraq.
You also had pharaniots who were still strong.
And lastly you had the Russians who were at war with the Ottomans at the time who would seek power in the Balkans.
So with all of these factors what would the map look like in lets say 1820, which of these groups would fall and which would rise?
