On November 4, 2008, Barack Obama won the United States presidential election to become the first African American elected to the office, defeating Senator John McCain in a contest shaped by economic collapse and war weariness.
The race had run for nearly two years. Obama, a first-term senator from Illinois, drew huge crowds with a message built around change and a call to cross old lines.
The lines were long. People waited for hours.
He took states that had not backed the Democratic ticket in decades, and his campaign used the early vote and a field operation tuned to turn out young and minority voters who had stayed home in past cycles, flipping the map in the industrial Midwest and along the coast in a sweep that few forecasts had put at this width.
The financial crisis set the stage. A year earlier, the housing market had cracked and banks faltered, and voters blamed the party in the White House, handing Obama an opening that his ads pressed by tying McCain to a record most voters wanted to leave behind.
In Chicago, more than a million people filled Grant Park to hear the speech, and the scene ran on television across the world, with many in the crowd old enough to recall a time when the ballot was denied to people who looked like the man they had just sent to the White House.
The win was historic. It did not end debate over race, but it cleared a barrier that had stood since the nation's founding, and the image of the night in the park became a reference point for a generation that came of age under a president whose name few had known a few years before.
