On March 7, 2015, President of the United States Barack Obama delivered a speech at Edmund Pettus Bridge to mark the 50th anniversary of the Selma to Montgomery marches on the subject of race relations within the United States. Among the estimated 40,000 present were former President George W. Bush, former First Lady Laura Bush, and Amelia Boynton Robinson, John Lewis, Diane Nash, Bernard Lafayette, and many other 'foot soldiers' who had taken part in the march in 1965.
