WASHINGTON -- Rising to face one of the largest gatherings of Americans in history, a solemn Barack Hussein Obama took the oath of office Tuesday as the nation's 44th president, pledging to begin the work of "remaking America" and proclaiming the arrival of "a new era of responsibility."
The 47-year-old son of a Kenyan father and Kansan mother, who became the first African-American president, recalled the nation's civil rights struggle in his inaugural address outside the U.S. Capitol, overlooking the National Mall.
"On this day," he said, "we gather because we have chosen hope over fear, unity of purpose over conflict and discord." He described himself, in a reminder both of his mixed heritage and of the distance the nation has traveled, as "a man whose father less than 60 years ago might not have been served at a local restaurant."
Obama took the presidential oath on the same Bible used to swear in Abraham Lincoln in 1861, as the nation veered toward civil war, two years before the Emancipation Proclamation ended slavery.
Obama's much-anticipated 20-minute address evoked the nation's founding principles of equality.
"The time has come to reaffirm our enduring spirit," he said. "To choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free and all deserve a chance to pursue their full measure of happiness."
Appealing to hope amid two wars and a shattered economy, the new president drew some of his loudest cheers when he said, "Starting today, we must pick ourselves up, dust ourselves off and begin again the work of remaking America."
But amid the calls to action and "a new era of peace," Obama also proclaimed what he called "a new era of responsibility" in which duty to others would claim a larger place. He challenged "some who question the scale of our ambitions" and "cynics [who] fail to understand ... that the ground has shifted beneath them."
