The United Panhellenic Organization of Youth (EPON) was established during a time of severe hardship for Greece, under Axis occupation following the 1941 invasion. The founders aimed to unite different youth organizations that had previously operated in isolation, creating a cohesive front to foster resistance against the oppressive regimes of Nazi Germany and its allies. The establishment took place in Athens, where influential youth leaders from diverse backgrounds rallied to form this organization, emphasizing the importance of youth engagement in the struggle for liberation alongside other resistance movements within Greece.

EPON’s structure allowed it to serve as a platform for youth education and activism, as it promoted national consciousness among young Greeks and provided a venue for expressing their discontent with the occupation. Activities included distributing underground literature, organizing protests, and executing sabotage efforts against the occupying forces. The organization quickly grew in influence and membership, attracting various young individuals eager to contribute to the nationalistic cause.

Throughout its existence, EPON played a critical role in energizing the resistance movement. The organization not only focused on military resistance but also emphasized cultural and social aspects of the fight for freedom—a dual approach that resonated with the broader population. As the war progressed, EPON became pivotal in shaping the identity of the future generation of Greek leaders and advancing the cause of liberation for their country.
