WASHINGTON — Donald John Trump was inaugurated as the 45th president of the United States on Friday, ushering in a new era that he vowed would shatter the established order and reverse a national decline that he called “this American carnage.”

In a ceremony that capped a remarkable rise to power, Mr. Trump presented himself as the leader of a populist uprising to restore lost greatness. He outlined a dark vision of an America afflicted by “the ravages” of economic dislocation and foreign exploitation, requiring his can-do approach to turn around.

“I will fight for you with every breath in my body, and I will never, ever let you down,” Mr. Trump told hundreds of thousands of rain-soaked admirers and onlookers in a forceful 16-minute Inaugural Address from the West Front of the Capitol.
