Monday marks one year since the shooting massacre at a gay nightclub in Orlando.
A special memorial was held Sunday night in Brooklyn to honor the victims.
Dozens gathered in Park Slope for a candlelight vigil and reading of the victim's names.
Organizers said it's crucial to remember those lost by acts of hate, especially during Pride Month.
"We always have to remember going back where our heritage is, back from Stonewall, back from Harvey Milk, to the New Orleans fire, now here to the one-year anniversary of Orlando. We have to have the memories," said Mickey Heller, co-chair of Brooklyn Pride.
"It's always good to remember people who have died of any kind of violence, homophobia, especially these days. Because if we don't respond it, who is going to respond when something happens to us?" said another person at the vigil.
Forty-nine people were killed when a gunman opened fire inside the Pulse night club.
The shooter was killed after a standoff with police.
It remains the deadliest mass shooting in U.S. history.
More vigils and memorials are planned throughout the day.
