Protesters took to Nottingham's Forest Recreation Ground in support of the Black Lives Matter movement.
Dozens of people heard speeches calling for equality in the workplace and better education on racial diversity in schools.
The event, on Sunday, June 28, was organised by Notts TUC along with those activists behind the first demonstration at the same site earlier this month.
It included a 'take a knee' demonstration.
The move follows weeks of protest started in the wake of George Floyd's death at the hands of police in America.
Mr Floyd died in Minneapolis on May 25 after police officer Derek Chauvin knelt on his neck for more than eight minutes.
A spokesman for the Notts Trade Council told Nottinghamshire Live: "Nottingham and Mansfield Trades Council believes that it is very important for trade unionists to support Black Lives Matter, Stand Up to Racism and other anti-racist organisations.
"History and recent events have shown that the structural inequalities in our society that trade unionist spend much of their time fighting against have disproportionate effects on black and ethnic minority groups.
"We stand shoulder to shoulder with all of those suffering."
Gillian Steele, 56, of Sneinton, had come to watch the speeches being given. She said: "I love the support that this garners. This is our most important issue. We have to keep it going. I will be at as many of these as I can until it is no longer an issue and we have true equality in our society."
Marcus Fotheringham, 39, of Aspley, added: "It's a great movement. This is peaceful and standing up for those who are subjected to systemic inequality and racism.
"It's not about getting angry, it's about education, listening and discussing.
"Of course all lives matter, but all this is about is asking to be on the same playing field, not always feeling like you're beneath someone else because of the colour of your skin."
