Macron's year-old movement - it does not even have the status of a party yet - has said it will field candidates in all 577 seats for the two-round parliamentary elections on June 11 and June 18.
Here are five things to know about French president-elect Emmanuel Macron. Macron has promised that half of those candidates will be new to elected politics.
The European Union breathed a sigh of relief at the election of a supportive French leader and the euro briefly hit a six-month high, but Macron faces a formidable challenge to enact his programme while trying to unite a fractured and demoralised country.
Freshly elected to the French presidency, Emmanuel Macron now faces an equally hard Act II: securing the parliamentary majority he needs to make good on his campaign promises to lift France out of economic gloom.
Macron is scheduled to attend a series of events and ceremonies with outgoing president Francois Hollande on Monday.
According to Le Monde, a quarter of registered voters did not show up to vote, making the turnout of 75 percent the lowest recorded in any final round of the presidential elections since 1969.
Macron, 39, is set to appoint a prime minister and form a government as soon as he takes office as the country's 25th and youngest president.
5 fast facts ahead of Celtics, Wizards Game 7 matchup
The game Thomas is referring to is Game 7 of the 2008 Eastern Conference semifinals between the Celtics and Cleveland Cavaliers. John Wall wasn't much help either, finishing with 18 points on 8-of-23 shooting and disappearing late in the game.
The opponents of Macron likely to follow the policies of Donald Trump like Le Pen would like to take France out of worldwide institutions, including both the European Union and North Atlantic Treaty Organisation; block borders; curtail trade; and impose quasi-Marxist state-dominated economics.
But Le Pen's 34 percent - a high in any national election for her far-right National Front - confirms her party as a formidable force, its French-first nationalism increasingly accepted by a growing swath of electors despite its history of anti-Semitism and racism.
Sylvie Goulard, a French deputy to the European Parliament, said Mr Macron would make Berlin his first official visit, with perhaps a stop to see French troops stationed overseas as well.
Macron will name his prime minister next week, but could be forced to amend his choice if the legislative elections don't go to plan.
Le Pen responded to defeat by vowing she would lead her anti-immigration National Front (FN) strongly into the legislative elections. In interviews on Monday her campaign director David Rachline said the party founded by her father would get a new name as bait to pull in a broader spectrum of supporters in France.
Macron is courageous leader and rejected the traditional politics.
Trump, who had hinted at support for Le Pen during the campaign, tweeted congratulations to Macron on a "big win" and said he looked forward to working with him.
