Bush's message of racial unity carried over to his selection of an ethnically diverse Cabinet -- including Colin Powell, the first black secretary of state.
Hundreds of thousands of spectators, some dressed in cowboy boots and hats from Bush's home state of Texas and others waving miniature American flags, braved the cold weather and sporadic rain to watch the inaugural ceremony.
Chief Justice William Rehnquist swore Bush in about noon, while Bush's twin daughters, Jenna and Barbara, looked on and his wife, Laura, held the same Bible used by George Washington during his inaugural ceremony in 1789 and Bush's father in 1989.
A 21-gun salute followed, disturbing the city's large population of pigeons from their perches.
The inaugural celebration, billed as "Celebrating America's Spirit Together," kicked off Thursday with an opening celebration at the Lincoln Memorial and ended Sunday morning with a service at the National Cathedral.
Bush, speaking on the steps of the Capitol building, broadly outlined his agenda -- re-emphasizing promises made on the campaign trail for education, military and Social Security reforms.
"And we will reduce taxes to recover the momentum of our economy and reward the effort and enterprise of working Americans," Bush added.
During the past weeks, Bush has voiced concerns about problems posed by a slowing economy and advocated his $1.6 trillion plan for tax cuts as the answer.
But the Republican's narrow control over the House and Senate might make it difficult for Bush to pass his more controversial proposals, including a school voucher plan.
Bush also departed from his campaign rhetoric and thanked the departing Clinton, who received a wave of applause from the crowd, for his service to the country.
During his campaign, Bush emphasized a need for the next chief executive to return morality to an office scarred by sexual scandals.
Bush also mentioned his election opponent, former Vice President Al Gore, during his inaugural address.

"And I thank Vice President Gore for a contest conducted with spirit and ended with grace," he said, drawing laughter from some partisans in the crowd.
The presidential election was mired in courts for more than a month, as judges debated how to count Florida's crucial electoral votes.
A U.S. Supreme Court decision led to Bush finally winning Florida's 25 votes and the election despite Gore's victory in the popular vote.
Bush made no other mention of the controversial election, which caused thousands of protesters to descend on the nation's capital, but emphasized cooperation throughout his speech.
" ... Our duty is fulfilled in service to one another. Never tiring, never yielding, never finishing, we renew that purpose today, to make our country more just and generous, to affirm the dignity of our lives and every life."
