The encyclopedia was founded in 1926 by Pavlos Drandakis (1896–1945) after the model of Encyclopædia Britannica.
He was helped by many well-known and qualified contributors and the result was deemed to be excellent.
Pavlos Drandakis reserved some rights of the encyclopedia which he later claimed in court.
After he won the trial, his descendants published a second edition of the encyclopedia in 1956 with Phoinix, Ltd.
Later on, four further volumes were issued in order to update the facts written in the encyclopedia.
