Many gatherings are expected to take place across the city Tuesday to mark one year since George Floyd's death at the hands of Minneapolis police.

Barclays Center has been the epicenter of many gatherings last summer after the video showing Floyd's fatal encounter with former officer Derek Chauvin sparked national conversation.

Caroline Gombe, of Black Women's March, is organizing a national walk out at 3 p.m. It will last 9 minutes and 29 seconds – the amount of time Chauvin knelt on Floyd's neck

"We would like to ask you all over America to take those 9 minutes and 29 seconds and think about the past year, but also think about what you can do from now on," Gombe says.

The same group is also organizing a rally and march starting at Cadman Plaza at 5 p.m.

Nupol Kiazolu, of Brownsville, is putting together a rally that starts at 8 p.m. outside the Brooklyn Museum.

"What happened to George Floyd was absolutely tragic, but nothing that was shocking to Black people because this has been our reality since the beginning of time in this country," Kiazolu says.

She says while a lot has changed in the past year and she feels optimistic, it's still important to continue the fight.

"Every single time I take the streets, I am reminded why I do this work and why it's so important and impactful," Kiazolu says. "The way we are able to bring together people from all walks of life that you would never expect at a Black Lives Matter protest, they're there."

A rally and march are also planned in Foley Square on Tuesday at 5 p.m.
