When a new French president is elected, their first trip abroad is to Germany. It's tradition.
And with that in mind, France's new President Emmanuel Macron spent his first full day in office visiting with German Chancellor Angela Merkel in Berlin.
The two leaders discussed Europe's future and pledged to do their best to hold the European Union together.
The union has faced a lot of issues in recent years, including a debt crisis, an influx of migrants, terrorist attacks and Brexit.
And France just faced an election where, at least in part, anti-European sentiment brought a far-right candidate all the way to runoff elections.
Both Merkel and Macron were open to eurozone reforms if necessary.
Macron was met with open arms and excited crowds when he arrived. But some in Germany are worried Macron's ideas about the economy could hurt Merkel in this year's election.
