Washington ? President Barack Obama said Sunday the legacy of the nation’s founding fathers has inspired freedom-seeking people around the globe for generations, including those rebuilding South Africa after the end of apartheid.

Obama addressed an enthusiastic crowd at the annual Ford’s Theatre gala Sunday, where South African Archbishop Desmond Tutu and South African Constitutional Court Justice Albie Sachs received the theater’s Lincoln Medal.

Tutu, who was introduced by poet Maya Angelou, spoke of the global need for peace and respect. He condemned last week’s clash in which nine activists were killed aboard a ship headed to the blockaded Gaza Strip.

He said he hoped his award would make “many more realize that revenge, retribution — no — are not the way to go. That true security is not something that comes from the barrel of a gun.”

Sachs was introduced by Supreme Court Justice Ruth Bader Ginsberg, who praised his record of “defending the oppressed and opposing evil in his native land in the grim years of apartheid.”

Sachs spoke of meeting Obama when the then-senator visited South Africa’s courts.

A longtime admirer of Abraham Lincoln’s writing, Sachs said he felt a connection between the historic president and Obama. This spark was made more powerful by Obama’s presence in South Africa, where Lincoln’s legacy was influential on the nation’s new leaders.
