Simitis's two consecutive terms marked the longest unbroken service of any modern Greek Prime Minister. Unlike predecessors who leaned towards skepticism of Western capitalism, Simitis often fostered closer ties with both capitalism and the United States, which resonated well with the electorate. Under his leadership, Greece adopted the euro in 2001, embracing a newfound sense of national confidence.

He also oversaw preparations for the 2004 Athens Olympics, which were viewed as a significant return to the birthplace of the Games. However, while these achievements initially signified stability and pride, they also contributed to a subsequent debt crisis that raised serious questions about Greece's future within the European Union. Many viewed the Olympic Games as a homecoming event, celebrating Greece's rich historical legacy.

The aftereffects of Simitis's tenure continue to influence discussions on Greek identity and its place in Europe, framing a complex narrative of achievement shadowed by fiscal challenges.
