Stylianos Vlasopoulos (Ital. Signore-Conte Stelio Vlassopulo) (1748–1822) was a scion of the aristocratic dynasty Vlassopoulos of Corfu, which was registered in 1642 in the Golden Book of the nobility (Libro d'Oro). Stylianos was the son of Don Timotheos Vlasopoulos and Countess Miloulias Bulgari of the known family of Corfu.
The first letters learned in the birthplace of Corfu and later left for Italy where he studied law and was named doctor at the University of Padua. He was judge of the Supreme Court, member of the judicial club of Corfu, lawyer, a member of the Ionian Academy  and politician of the Ionian Islands in key positions in the offices of Senator, legislator, mayor of Corfu and Governor of Lefkada.
During Vlassopoulos's tenure in Lefkada, Ali Pasha sent an ultimatum[according to whom?] to Stylianos Vlasopoulos give him the armatolous, who they were persecuted by Ali and they fled to Lefkada in their families. Vlasopoulos deliberately raised various obstructions, so Ali ordered the concentration of cannon and troops in Arta, Preveza and Vonitsa and on land across from the island in order to invade it. Vlasopoulos succeeded through his diplomatic skills to save the Greek people of Lefkada from slaughter at the last minute.
In the last years of his life, he served as advisor to the government of the State of the Ionian Islands. In Corfu, he worked as a judge and a lawyer while he devoted herself to writing. He published works in Italian by someone[according to whom?] using the pseudonym Biagio Colonna (who according to at least one author,[according to whom?] Michael Pratt, was Vlassopoulos himself ), including La Difesa della Chiesa Greca (The Defense of the Greek Church) , written in 1800 and placed on the Index Librorum Prohibitorum in 1803. For a period of his life, he was editor of Corfiot publications Mercurio Litterario (1805–1808) and Gazetta Urbana (1802–1803).
