12. Francois Hollande

Title: President of France

Country: France

Age: 61

It hasn’t been an easy 12 months for French President Francois Hollande. He's dealt with multiple terrorist attacks in Paris, stepped up France’s role in the fight against ISIS, and instituted reforms to the country’s social policy, like extending the retirement age for private-sector workers.

Hollande also saw his approval ratings continue to dip down to 20% as the year wore on. Though he’s slowly making progress in his attempts to lift both French morale and favor among his constituents, Hollande has a long way to go. But he still commands the fifth-richest nation on the continent and one of the most influential members of the EU, giving him immense power regardless of approval ratings.
