The Pulse Nightclub Shooting
On June 12, 2016, a gunman opened fire inside Pulse, a gay nightclub in Orlando, Florida, during Latin Night, killing forty-nine people and wounding fifty-three others in the deadliest attack on the LGBTQ+ community in American history and the deadliest mass shooting in the United States at that time. The shooter, twenty-nine-year-old Omar Mateen, called 911 during the attack to pledge allegiance to ISIS. He was killed by police after a three-hour standoff during which he held dozens of survivors hostage in the club's bathrooms.
The investigation by the FBI and Orlando Police Department was complex and immediately politically charged. While Mateen had expressed support for multiple and mutually contradictory terrorist organizations — ISIS, Hezbollah, and al-Qaeda — investigators found no evidence of direct contact with any foreign terrorist group or of operational direction from abroad. Evidence also suggested Mateen may have been a closeted gay man who frequented Pulse and used gay dating apps, raising questions about whether self-hatred and internal conflict played a significant role alongside extremist ideology.
The attack triggered the largest criminal investigation in Florida history. Questions arose about whether the FBI had missed opportunities to intervene: Mateen had twice been investigated by the bureau between 2013 and 2014 for possible extremist sympathies before both investigations were closed without action. The FBI reviewed its procedures, and a Justice Department inspector general report found deficiencies in how the prior investigations had been handled.
Pulse Nightclub became a memorial site and a symbol of LGBTQ+ resilience and vulnerability. The forty-nine victims — predominantly young Latino men and women — were memorialized through the onePULSE Foundation and a proposed national memorial on the site. The shooting accelerated congressional debate about assault weapons and background check legislation, though no major federal gun legislation was passed in its immediate aftermath. It remains one of the most culturally significant hate crimes and mass shooting events in American history.
