Abdul Hamid II, Sultan of the Ottoman Empire, publicly announces the creation of the Ullah millet for the Aromanians of the empire, which had been established one day earlier. For this reason, the Aromanian National Day is usually celebrated on May 23, although some do so on May 22 instead.

Abdülhamid II or Abdul Hamid II was the 34th sultan of the Ottoman Empire, from 1876 to 1909, and the last sultan to exert effective control over the fracturing state. He oversaw a period of decline with rebellions, and presided over an unsuccessful war with the Russian Empire (1877–78), the loss of Egypt, Cyprus, Bulgaria, Serbia, Montenegro, Tunisia, and Thessaly from Ottoman control (1877–1882), followed by a successful war against Greece in 1897, though Ottoman gains were tempered by subsequent Western European intervention.
