Andreas Georgiou Papandreou was a Greek economist, politician, and a dominant figure in Greek politics, known for founding the political party PASOK, which he led from 1974 to 1996. He served three terms as the 3rd and 8th prime minister of Greece.

The Panhellenic Socialist Movement, known mostly by its acronym PASOK, is a social-democratic political party in Greece. Until 2012 it was one of the two major parties in the country, along with New Democracy, its main political rival. In the June 2023 Greek legislative election it once again held firm on to its position of one of the ”big three” political parties of Greece.
