Analysis of information sources in references of the Wikipedia article "Războiul de Independență al Greciei" in Romanian language version.
The Greek revolt was precipitated on 25 martie 1821, when Bishop Germanos of Patras raised the flag of revolution over the Monastery of Agia Lavra in the Peloponnese. The cry “Freedom or Death” became the motto of the revolution. The Greeks experienced early successes on the battlefield, including the capture of Athens in June 1822, but infighting ensued.
The revolt began in March 1821 when Alexandros Ypsilantis, the leader of the Etairists, crossed the Prut River into Turkish-held Moldavia with a small force of troops. Ypsilantis was soon defeated by the Turks, but, in the meantime, on 25 martie 1821 (the traditional date of Greek independence), sporadic revolts against Turkish rule had broken out in the Peloponnese (Modern Greek: Pelopónnisos), in Greece north of the Gulf of Corinth (Korinthiakós), and on several islands. Within a year the rebels had gained control of the Peloponnese, and in January 1822 they declared the independence of Greece. The Turks attempted three times (1822–24) to invade the Peloponnese but were unable to retrieve the area.
