Mr. Biden’s speech accepting his party’s presidential nomination capped one of the most extraordinary Democratic National Conventions in history.
The final night hammered home the campaign’s message of the reunification, and its depiction of Mr. Biden as a big-tent candidate for a big-tent moment.
Here are four moments that defined the last night of the convention.
Biden called for national healing.
All week long, Democratic speakers struck a tone of urgency, not contenting themselves with the campaign cliché that “this is the most important election in our lifetimes.” Instead, they warned starkly about the very future of American democracy.
In his speech, Mr. Biden returned to those themes.
“This is a life-changing election,” Mr. Biden added. “This will determine what America is going to look for a long time.”
Former rivals warmly embraced Biden’s candidacy.
In a final convention show of unity, Senator Cory Booker played host to a “Hollywood Squares”-type reunion of seven former presidential candidates, who offered their favorite memories of Mr. Biden, with some occasional comic relief from Senator Bernie Sanders.
“You can think of this sort of like ‘Survivor’ on all of the people who have also ran,” Mr. Booker said. (Before moderating the tributes and recollections for Mr. Biden, Mr. Booker had a question for Mr. Sanders: “Why does my girlfriend like you more than me?”)
Julia Louis-Dreyfus added a comedic touch.
Julia Louis-Dreyfus, the actor and Emmy-winning star of “Veep” who was Thursday night’s M.C., peppered her transitions with breezy but cutting comedy.
Ms. Louis-Dreyfus set the tone early when bantering with Andrew Yang, the former presidential candidate. The two intentionally mispronounced Vice President Mike Pence’s name — a jab at the conservative pundits and politicians who regularly mangle Senator Kamala Harris’s given name.
A tribute to John Lewis, and a call to action.
Mayor Keisha Lance Bottoms of Atlanta paid tribute to Representative John Lewis of Georgia, saying that the civil rights leader’s life story and passion for making “good trouble” represented the ideal the Democratic Party has been reaching for over the past week.
“He walked gently amongst us, not as a distant icon but as a God-fearing man who did what he could to fulfill the as-yet-unfulfilled promise of America,” Ms. Bottoms said. She made particular note of Mr. Lewis’s signature issue, voting rights.
