Amazing Grace! How sweet the sound!

Henry Louis Gates, Jr on the election.

We have all heard stories about those few magical transformative moments in African-American history, extraordinary ritual occasions through which the geographically and socially diverse black community—a nation within a nation, really—molds itself into one united body, determined to achieve one great social purpose and to bear witness to the process by which this grand achievement occurs.

The first time was New Year's Day in 1863, when tens of thousands of black people huddled together all over the North waiting to see if Abraham Lincoln would sign the Emancipation Proclamation. The second was the night of June 22, 1938, the storied rematch between Joe Louis and Max Schmeling, when black families and friends crowded around radios to listen and cheer as the Brown Bomber knocked out Schmeling in the first round. The third, of course, was Aug. 28, 1963, when the Rev. Dr. Martin Luther King Jr. proclaimed to the world that he had a dream, in the shadow of a brooding Lincoln, peering down on the assembled throng, while those of us who couldn't be with him in Washington sat around our black-and-white television sets, bound together by King's melodious voice through our tears and with quickened-flesh.

But we have never seen anything like this. Nothing could have prepared any of us for the eruption (and, yes, that is the word) of spontaneous celebration that manifested itself in black homes, gathering places and the streets of our communities when Sen. Barack Obama was declared President-elect Obama. From Harlem to Harvard, from Maine to Hawaii—and even Alaska—from "the prodigious hilltops of New Hampshire … [to] Stone Mountain of Georgia," as Dr. King put it, each of us will always remember this moment, as will our children, whom we woke up to watch history being made.
