True to his pre-election nickname Speedy, kinetic French President Nicolas Sarkozy occupied the global stage with the activist leadership that has become his trademark. Sarkozy succeeded in overcoming initial opposition to become the driving force behind a successful international intervention in Libya, teamed up with German Chancellor Angela Merkel to spearhead efforts to save the euro, ordered France's unexpected vote to make Palestine a full member of UNESCO and hosted the G-20's annual summit in Cannes at the same time Europe's debt crisis risked explosion. Sarkozy's biggest challenge awaits him in 2012, however, with an uphill re-election bid as he carries out painful austerity cuts in the face of plunging economic-growth forecasts.
From tsunamis to budget battles to revolutions, 2011 has been a tumultuous, news-packed year. Who influenced the news most, for better or worse? Tradition dictates that TIME's editors choose the Person of the Year. Now that voting has closed, view the final ratings.
