Once Kamala Harris took the stage on the final night of the Democratic National Convention, she made history.

The vice president formally accepted the party's nomination for president, becoming the first Black woman or first person of South Asian descent to do so. If she wins November's election, she would be the first woman president in U.S. history.
After a weeklong convention that touted her personal story and her career as a prosecutor and in politics, a cavalcade of speakers described Harris to voters as a "joyful warrior" and defender of personal freedoms and democracy — a stark contrast to the agent for division they'd find in her opponent, former President Donald Trump.
In her speech, she laid out a choice for voters on Election Day.
"With this election, our nation has a precious, fleeting opportunity to move past the bitterness, cynicism, and divisive battles of the past," she said. "A chance to chart a new way forward. Not as members of any one party or faction, but as Americans."
Harris' ascension this election season was swift. She stepped in after President Joe Biden faced mounting pressure to exit the race. In a matter of weeks, Democratic leaders and voters coalesced around Harris as their best chance to win the Oval Office.
With fewer than 75 days before the election, that urgency carried to her message to voters in the biggest speech of her political career: The nation can move forward and leave Trump behind.
"America, we are not going back," she said.
