Answer: The liberal nationalism which began in Europe sparked an uprising in Greek in 1921. This led to the Greek War of Independence from 1921 to 1929.
The Greek War of Independence is also called the Greek Revolution. It took place between 1821 and 1832. It was fought against the Ottoman Empire. The Russian Empire, Great Britain, Kingdom of France and many other European powers helped them in their efforts. The Eyalets of Egypt, Algeria and Tripolitania, and the Beylik of Tunis were on the side of the Ottomans.
The war went on for 8 years, 6 months and 3 weeks. It took place in the Balkans and the Aegean Sea. Finally the Greek won. The First Hellenic Republic was established. The Treaty of Constantinople was signed.
Finally with the Treaty of Constantinople, 1832, Greece was recognised as an independent nation from the Ottoman Empire.
