In 1909, A Arab society was formed in Paris called The Young Arab society (Sounds familiar) or Al-Fatat, formed by Syrian Arab Muslims, who wanted Arab equality in the Ottoman Empire. How did the group want to do this?
They proposed, instead of an independent Arabia, a United binational union between the Ottoman Empire' and the Arab provinces, too form a Turco-Arab union. They drew inspiration from Austria-Hungary as the model for the new state.
Tawfiq al-Natur, a founding member of the party stated
"All that we, as Arabs, wanted was to have the same rights and obligations in the Ottoman Empire as the Turks themselves and to have the Empire composed of two great nationalities
Turk and Arab"
---------------
So, what if the Turko-Arabian empire succeeded? And the Young Arab society got what they wanted? How could this happen? The POD could be from 1908-1918
Or it could be further back if you want.
