Legendary boxer Muhammad Ali is known for his confidence in and out of the ring, as well as for his humanitarian and civil rights efforts. Now, the famed boxer is being honored with a Liberty Medal.

The Associated Press reports Ali will be honored with one of these recognition awards in a ceremony on September 13 in Philadelphia at the National Constitution Center.

"Muhammad Ali symbolizes all that makes America great, while pushing us as a people and as a nation to be better," David Eisner, the National Constitution Center president and chief executive officer, said in a statement according to the AP. "Each big fight of his life has inspired a new chapter of civic action."

The National Constitution Center reports the Liberty Medal is awarded annually to men and women of "courage and conviction who have strived to secure the blessings of liberty to people the world over."

Past recipients include Sandra Day O'Connor, Kofi Annan and Colin Powell.

According to the AP, Ali is being honored with this year's award due to his continued courage and conviction, including his "outspoken advocacy for civil and religious freedom," as well as his philanthropy and humanitarian efforts over the years.
