Emmanuel Macron was sworn in Sunday as France's new president, and its youngest in history, in a morning of pomp, circumstance and solemnity that included a 21-cannon salute and a ceremony at the tomb of the unknown soldier. Macron, 39, sought to send signals of personal modesty, per Reuters, including by wearing a suit that cost $500 as opposed to a more expensive designer option.

He met with Francois Hollande, his predecessor and mentor, for an hour, and received the French nuclear launch codes.

From the new president: "The division and fractures in our society must be overcome. I know that the French expect much from me. Nothing will make me stop defending the higher interests of France and for working to reconcile the French."
