Arsakeion is a group of co-educational independent schools in Greece, administered by the non-profit organization Philekpaideutiki Etaireia. It comprises six schools, with campuses in Patras (1891), Psychiko (1933), Thessaloniki (1936), Ekali (1972), Tirana (1999), and Ioannina (2009). Philekpaideutiki Etaireía was founded in 1836, when Ioannis Kokkonis, Georgios Gennadios and Misail Apostolidis created a school where young girls could be educated after the difficult years of the Greek War of Independence. The school was endowed by the magnate Apostolos Arsakis and was named after him. Initially it was a girls-only boarding school located at Panepistimiou Street in downtown Athens, purposed to train young teachers and send them (before 1913) to Macedonia, in order to help survival of the Greek language and culture. Following Arsakis' death, the school was further endowed by Baron Michael Tositsas and his widow, Helen. Combining a tradition of educational excellence along with appeal to more affluent families, the school flourished and created campuses in Patras (1891), Psychiko (1933), Thessaloniki (1936), Ekali (1972), Tirana (1999), and Ioannina (2009). The schools started enrolling boys in 1982. The original building on Panepistimiou Street now houses the Council of State.
