"In a year where world leaders were tested all through the year, no one was tested the way she was," TIME Managing Editor Nancy Gibbs said Wednesday on "The Today Show."
Gibbs explained the decision in even more detail on TIME:
Not once or twice but three times this year there has been reason to wonder whether Europe could continue to exist, not culturally or geographically but as a historic experiment in ambitious statecraft. Merkel had already emerged as the indispensable player in managing Europe's serial debt crises; she also led the West's response to Vladimir Putin's creeping theft of Ukraine. But now the prospect of Greek bankruptcy threatened the very existence of the euro zone. The migrant and refugee crisis challenged the principle of open borders. And finally, the carnage in Paris revived the reflex to slam doors, build walls and trust no one.
Each time Merkel stepped in.
Gibbs revealed the top 5 candidates during her "Today" appearance as well, which included Hassan Rouhani at number five and Black Lives Matter activists at four.
