ATLANTA — Martin Luther King's flame has always burned brightest in Atlanta, but in a real sense, the torch is being passed to Washington, D.C., with his birthday and holiday taking on dual meaning for many Americans because it falls on the eve of Barack Obama's inauguration.

While Georgia's capital has traditionally been the place for the most high-profile observance that day, this year it will share the spotlight with the nation's capital.

But the shift from King's hometown does nothing to diminish the excitement of the moment, said William Jelani Cobb, an American history professor at Atlanta's Spelman College.

"That we would have a celebration of King's birth and the inauguration of the first black president on consecutive days is almost too much to ask for," Cobb said. "(Barack) Obama's election represents the fulfillment of the most well-known of King's dreams, that people would be judged by the content of their character."

As for Obama, part of his King Day will be spent volunteering as part of a national call for service.

Still, Atlanta will be in the spotlight with the traditional pomp and circumstance at King's spiritual home, Ebenezer Baptist Church, including the ceremonial wreath laying at the tomb and the ecumenical service. But this year's keynote speaker is Pastor Rick Warren, a Southern Baptist who opposes gay marriage. That speech is just a warm-up, with Warren traveling to Washington to give the invocation at Tuesday's inauguration. Gay advocates assailed Obama for choosing Warren, while many conservative Christians hailed the pick.

For many, Obama's swearing in will be a culmination of a long holiday weekend in D.C. for King and inaugural events.

La'Keitha Daniels, an attorney in Atlanta, has been to the King service at Ebenezer, where King preached from 1960 until his assassination in 1968. She was also there last year when Obama came on the Sunday before the federal holiday.

This holiday, though, will be spent honoring both men in Washington.

"Hundreds of thousands of people are going there because it's the beginning of Dr. King's dream being realized," Daniels said. "Everyone feels that we are truly on the cusp of change and seeing the things he only dreamt about becoming a reality."

King's nephew, Isaac Newton Farris Jr., believes his uncle's birthday has even more special meaning this year.

"Clearly, we set the tone in Atlanta in past years," said Farris, president and chief executive officer of The King Center where the preacher and his widow, Coretta Scott King, are entombed and where an eternal flame burns in the civil rights leader's honor.
