Fifty years later, politicians and civil rights leaders sang and praised alongside congregants to remember of the bombing of the 16th St. Baptist Church in Birmingham.
In attendance were religious and political figures from across the country.
The bombing, which claimed the lives of four little girls, is considered one of the galvanizing events of the civil rights movement.
Speaker Condoleeza Rice, Former Secretary of State, said, "We also look forward, because in looking forward, it's truly that we honor their sacrifice. If we remember that equality and justice for all, written in the constitution, is actually not just a piece of paper, but something that each and every one of us must live each and every day."
No one was arrested for fourteen years after the bombing. Robert Chambliss was eventually convicted of the crime in 1977.
