In 1923, Italy occupied the Greek island of Corfu after accusing the latter of assassinating the Italian general Enrico Tellini. The Corfu incident prompted Greece to create the Corfu Information Center under Georgios Fessopoulos. The center was tasked with countering Italian propaganda, disrupting trade with Italy, limiting Catholic proselytism and the use of the Italian language. Apart from that the center also monitored the activities of Armenian refugees and pacifists residing on the island, for fear that they might be communist agents. On 25 September 1925, Theodoros Pangalos founded the National Special Security Service (YAK) under the auspices of the Hellenic Gendarmerie. Tasked with combating the seditious Communist Party of Greece, the organization was paralyzed by an internal power struggle. On 27 December, Fessopulos took over the YAK on 29 January 1926, YAK was renamed into the National General Security Service (YGAK), which now fell under the command of the Ministry of the Interior. The YGAK continued to gather intelligence on communists and illegal aliens. In August 1926, Pangalos was overthrown in a countercoup by Georgios Kondylis. Kondylis dissolved YGAK due to its close affiliation with Pangalos, leaving Greece without an intelligence agency for the next ten years.
