Marchers held up signs that read, "Black Lives Matter" and "Embrace Diversity." Others condemned the racism of the weekend’s march in Charlottesville.
Tucsonan Tiffany Smith said she could not stand by after the weekend’s racist protests.
"I believe that white supremacy and racist and racism have no place in our society," she said.
Further ahead in the march, Andre Mixon.
"As you noticed at Charlotte’s march, it was mostly white males. If you look amongst the crowds here, you see the diversity of what America really looks like," Mixon said.
The event wasn’t without its politics. It was organized by Billy Kovacs, a Democratic contender for Republican Martha McSally’s seat.
"This is Tucson, this is our community," Kovacs said. "We come out in force against things we don’t believe are the fabric of our community."
Police did not report any injuries or clashes with counter protesters.
