The National Solidarity (Greek: E.A.) was the social welfare organization of the EAM resistance movement in occupied Greece during World War II. The decision to establish a resistance organization was made by Pantelis Karagitsis, Lefteris Apostolou, and Aristotelis Bouras, who had just escaped from the internal exile imposed by the pre-democratic Metaxas regime. National Solidarity was founded on May 28, 1941, just a month after the beginning of the occupation, in a park behind the Soteria Hospital. It holds the distinction of being the first nationwide resistance group established in Greece. The founding members included Kleon Papaloizos, who was also elected as secretary, Vasileios Markezinis, Dionysia Papadomichelaki, Nikos Dresios, Georgios Vasilopoulos, and Spyros Antypas.
