The Panhellenic Socialist Movement (PASOK) is a political party in Greece founded in 1974 by Andreas Papandreou. It emerged as a significant force in Greek politics, advocating for socialist policies and social democracy. PASOK played a crucial role in shaping modern Greek political landscape, especially during the 1980s and 1990s when it held power multiple times. The party's platform includes promoting social justice, economic development, and public welfare. Over the years, PASOK has faced challenges, including declining popularity and internal divisions, particularly during the financial crisis that began in 2009, which affected its electoral support and influence in Greek politics.
