First lady Michelle Obama was making her first appearance of the presidential campaign. Sanders was taking the stage in a highly anticipated address, as was Massachusetts Senator Elizabeth Warren, a favourite of liberals and one of the party's toughest critics of Republican Donald Trump.
"Trump thinks he can win votes by fanning the flames of fear and hatred," Warren said in excerpts released ahead of her speech. "By turning neighbour against neighbour. By persuading you that the real problem in America is your fellow Americans -- people who don't look like you, or don't talk like you, or don't worship like you."
While her ouster was a major victory for Sanders, it wasn't enough to ease the frustration of his supporters. Chants of "Bernie" echoed through the arena as the convention opened, and boos could be heard at times when Clinton's name was raised.
Outside the convention hall, several hundred Sanders backers marched down Philadelphia's sweltering streets. Signs carried messages such as "Never Hillary," and police said 55 people were cited for disorderly conduct after trying to climb barricades near the Democratic convention.
Clinton's team hoped Wasserman Schultz's resignation -- along with an apology from the DNC to Sanders and his supporters -- would keep the convention floor calm. But Sanders' aides reached out to the Clinton campaign Monday afternoon to express concerns that supporters would still try to disrupt the proceedings, according to a Democratic official.
Indeed, the convention featured young immigrants speaking
of their love for America and labour leaders backing Democratic economic policies. The program was also chockfull of up-and-coming Democratic lawmakers.
Wasserman Schultz had planned to be among those taking the stage, despite the email hacking controversy. But she stepped aside, bowing to pressure from Democrats who feared the mere sight of her on stage would prompt strong opposition from Sanders' backers.
Sanders previewed his remarks during an appearance earlier yesterday before supportive delegates. He implored them to vote for Clinton, generating a chorus of boos.
"Brothers and sisters, this is the real world that we live in," Sanders said as he tried to quiet the crowd. "Trump is a bully and a demagogue."
