Emmanuel Macron laid out his plan for France on Sunday after becoming the country's youngest leader since Napoleon.
In his inauguration speech, Macron promised to combat authoritarianism, terrorism, climate change and the "excesses of capitalism in the world." He pledged to find a solution to the global migrant crisis and called for a "more efficient, more democratic" European Union.
France's last administration struggled with high unemployment and low economic growth on top of repeated terror attacks that left more than 230 people dead.
As part of the official exchange of power, outgoing President François Hollande gave Macron the launch codes for France's 300 nuclear warheads. France will become the only EU member with nuclear weapons once Brexit is complete.
Macron's self-founded party doesn't hold any seats in the French National Assembly. With those elections in June, Macron has pledged to have a candidate for all 577 of France's legislative seats. More than 400 candidates have already been announced.
