Rigas Feraios or Rigas Velestinlis (Greek: Ρήγας Βελεστινλής-Φεραίος, born Αντώνιος Κυριαζής, Antonios Kyriazis; also known as Κωνσταντίνος Ρήγας, Konstantinos or Constantine Rhigas; Serbian: Рига од Фере, Riga od Fere; 1757—June 13, 1798) was a Greek writer and revolutionary, an eminent figure of Greek Enlightenment, remembered as a Greek national hero, the first victim of the uprising against the Ottoman Empire and a forerunner of the Greek War of Independence.
He later went to the monastic community of Mount Athos, where he was received by Kosmas, prior of the Vatopedi Monastery; from there to Constantinople (Istanbul), where he was a secretary to the Phanariote Alexander Ypsilanti. Arriving in Bucharest, the capital of Wallachia, Feraios returned to school, learned several languages and eventually became a clerk for the Wallachian Prince Nicholas Mavrogenes. When war broke out between the Ottomans and Imperial Russia in 1787 (see Russo-Turkish War, 1787-1792), he was charged with the inspection of the troops in Craiova.
Here, he entered into close and friendly relations with an Ottoman officer named Osman Pazvantoğlu, afterwards the famous rebellious Pasha of Vidin, whose life he saved from the vengeance of Mavrogenes. He learned about the French Revolution and came to believe something similar could occur in the Balkans, resulting in self-determination for the Eastern Orthodox Ottoman population; Feraios developed support for an uprising by meeting with Greek bishops and guerrilla leaders.
After the death of his patron, Feraios returned to Bucharest to serve for some time as dragoman at the French consulate. At this time he wrote the famous Greek version of La Marseillaise, the anthem of French revolutionaries, a version familiar through Lord Byron's paraphrase as "sons of the Greeks, arise".
He printed pamphlets based on the principles of the French Revolution, including Declaration of the Rights of Man and of the Citizen and a New Political Constitution of the Inhabitants of Rumeli, Asia Minor, the Islands of the Aegean, and the principalities of Moldavia and Wallachia'' — these he intended to distribute in an effort to stimulate a Pan-Balkan uprising against the Ottomans. He also published many Greek translations of foreign works, and collected his poems in a manuscript (posthumously printed in Iaşi, 1814).
From Belgrade, he was to be sent to Constantinople to be sentenced by Sultan Selim III. While in transit, he and his five collaborators were strangled to prevent their rescue by Feraios' friend Osman Pazvantoğlu. Their bodies were thrown into the Danube River.
Feraios' last words are reported as being: "I have sown a rich seed; the hour is coming when my country will reap its glorious fruits".
His grievances against the Ottoman occupation of Greece regarded its cruelty, the drafting of children between the ages of five and fifteen into military service (Devshirmeh or Paedomazoma), the administrative chaos and systematic oppresion (including prohibitions on teaching Greek history or language, or even riding on horseback), the confiscation of churches and their conversion to mosques. Feraios wrote enthusiastic poems and books about Greek history and many became widely popular. One of the most famous (which he often sang in public) is the Thourio in which he wrote, "It's better to have an hour as a free man than forty years as a slave" («Ως πότε παλικάρια να ζούμε στα στενά…. Καλλιώναι μίας ώρας ελεύθερη ζωή παρά σαράντα χρόνια σκλαβιά και φυλακή»). He urged Greeks to leave the Ottoman-occupied towns for the mountains, where they might experience more freedom.
A statue of Rigas Feraios stands at the entrance to the University of Athens. There is also a statue of his in Belgrade at one end of the street that bears his name (Ulica Rige od Fere).
Rigas Feraios was also the name of the youth wing of the Communist Party of Greece (Interior), in honour of the poet. A split of this youth wing was Rigas Feraios - Second Panhellenic.
