The country adopted the euro in 2001 and successfully hosted the 2004 Summer Olympic Games in Athens. More recently, Greece has suffered greatly from the late-2000s recession and has been central to the related European sovereign debt crisis. Due to the adoption of the euro, when Greece experienced financial crisis, it could no longer devalue its currency to regain competitiveness. Youth unemployment was especially high during the 2000s. The Greek government-debt crisis, and subsequent austerity policies, have resulted in protests and social strife. Left-wing Syriza, led by Prime Minister Alexis Tsipras, governed Greece since 2015 until 2019. Syriza gained support by opposing the austerity policy that had affected Greeks since the beginning of the Greek government-debt crisis. However, prime minister Tsipras was succeeded by Kyriakos Mitsotakis after the landslide victory of centre-right New Democracy in the 2019 elections.
