After various adventures he returned to Athens. He was elected as member of the "Ephorate of Athens". When Omer Vrioni arrived in Attica and the Athenians abandoned the city, he fled to Aegina, where he developed significant activity. He was distinguished as a representative in the National Assemblies of Epidaurus and Astros and for a short period (January–February 1822) he served as second secretary of the Legislative Corps. In 1824, upon the recommendation of the English colonel Leicester Stanhope, Psyllas undertook the publication of the "Εφημερίς των Αθηνών" ("Newspaper of Athens", August 1824 – April 1826).
