Kamala Harris has accepted the Democratic nomination for president on the final night of the party convention in Chicago.
Harris pledged to lead "for all Americans" and create an "opportunity economy" in a highly personal headline speech.
Other key themes included protecting the right to abortion, unity and working-class aspiration.
Harris also called for a ceasefire in Gaza, but did not address directly the protests taking place outside the convention over US support of Israel.
Republican rival Donald Trump gave a running on social media, saying: "Why didn’t she do something about the things of which she complains?".
Democrats have been riding on a surge of enthusiasm since Harris became their nominee, but polls suggest the election remains extremely tight.
