The village existed during the struggle for the independence of Greece (1821-1829) and many of its members participated in this struggle, namely the families: Alexiou (Giannakis, Stavros), Valtinos (Athanasios, Kolios, Georgakis, Georgios, Ioannis, Panos, Dimitrios and Sotiris), Kontogiannis (Mitsos, Vaggelis, Nikolaos, Spyros), Mylonas Zacharis, Nikou Andreas, Sotiris Dimos, Christou Konstantinos, Christou or Seltsikas Spyros and others.

The original settlement is now mostly abandoned by its inhabitants (population 66 people according to the 2021 census).

A new settlement was created along the bank of the river Inachos with the name "New Chalkiopoulo (Νέο Χαλκιόπουλο)".

Authors Kostas Hatzopoulos and Mitsou Andreas derive their origin from Chalkiopoulo.

The population of Agios Vlasios (Greek: Άγιος Βλάσιος) was 15 at the 2021 census.
