WASHINGTON (CNN) -- Fifty years ago today, Martin Luther King Jr. spoke at the Lincoln Memorial and told of his dream for America. Now, half a century later, people will gather again to remember his words and look ahead to where they could still take this nation.
It's a day forever etched in American history; sending forth lasting ideas and ideals from a king. Over 250,000 people attended, but untold numbers, worldwide, were inspired.
Now, fifty years later at the same place, some from that generation and newer ones hope to evoke the spirit of that day. Rev. Jesse Jackson said, "Dr. King took us to another level. This was a high mountain moment of hope."
Then as now, dignitaries from all races and creeds are slated to speak such as Oprah Winfrey, Leann Rimes and Jamie Foxx, civil rights icons like John Lewis and Caroline Kennedy, and presidents Jimmy Carter, Bill Clinton, and Barack Obama.
following up a 2011 dedication where the nation's first black president praised the first black man to receive a monument on the mall. President Obama said, "Without that shining moment, without Dr. King's glorious words, we might not have had the courage to come as far as we have."
