ATHENS, GREECE — Costas Simitis, former prime minister of Greece and the architect of the country’s joining the common European currency, the euro, has died at age 88, state TV ERT reported. Simitis was taken to a hospital in the city of Corinth early Sunday morning from his holiday home west of Athens, unconscious and without a pulse, the hospital’s director was quoted as saying by Greek media. An autopsy will be performed to determine the cause of death. The government decreed a four-day period of official mourning. Simitis will receive a state funeral. Warm tributes appeared, and not just from political allies. “I bid farewell to Costas Simitis with sadness and respect. A worthy and noble political opponent,” Prime Minister Kyriakos Mitsotakis said in a Facebook post, also saluting the “good professor and moderate parliamentarian.” Another conservative politician, former European Commissioner Dimitris Avramopoulos, recalled how he, as mayor of Athens, had cooperated “seamlessly and warmly” with Simitis in organizing the Olympic Games. “He served the country with devotion and a sense of duty. … He was steadfast in facing difficult challenges and promoted policies that changed the lives of [many] citizens,” Avramopoulos added. Simitis, a co-founder of the Socialist PASOK party in 1974, eventually became the successor to the party’s founding leader, Andreas Papandreou, with whom he had an often contentious relationship that shaped the party’s nature. Simitis was a low-key pragmatist where Papandreou was a charismatic, fiery populist. He was also a committed pro-European, while Papandreou banked on strong opposition to Greece’s joining what was then the European Economic Community in the 1970s, before changing tack once he became prime minister. When the profligate first four years of socialist rule, from 1981 to 1985, resulted in a rapidly deteriorating economy, Papandreou elevated Simitis to be finance minister and oversee a tight austerity program. Finances improved, inflation was partly tamed, but Simitis was pushed to resign in 1987 when Papandreou, eyeing an upcoming election, announced a generous wages policy, undermining the goals of the austerity program. The socialists returned to power with Papandreou still at the helm in 1993, but he was ailing and finally resigned the premiership in January 1996. A tight two rounds of voting among the socialist lawmakers unexpectedly elevated Simitis to the post of prime minister, a post he held until 2004. Simitis considered Greece’s entry into the eurozone, in January 2001, as the signature achievement … “Costas Simitis, former Greek prime minister and socialist leader, dies at 88” →
