In short: On February 26, 2012, 17-year-old Trayvon Martin was killed by a neighborhood watch volunteer in Sanford, Florida. The subsequent acquittal of George Zimmerman sparked nationwide protests, fueled intense debates over racial profiling and self-defense laws, and served as the catalyst for the formation of the Black Lives Matter movement.

Trayvon Martin, a 17-year-old African American high school student, was walking home from a convenience store in the Retreat at Twin Lakes community when he was spotted by George Zimmerman, a 28-year-old neighborhood watch volunteer. Zimmerman, who had reported a series of local burglaries, contacted the police non-emergency line to describe Martin as suspicious. Despite being advised by a dispatcher not to follow the teenager, Zimmerman pursued him. A physical altercation ensued, resulting in Zimmerman fatally shooting the unarmed Martin.

Following the shooting, Zimmerman claimed he acted in self-defense, citing injuries including a bloody nose and head lacerations. Local police initially declined to charge him, citing a lack of evidence to contradict his account and Florida’s stand-your-ground law. This decision triggered widespread public outcry and demonstrations across the United States. In April 2012, Florida Governor Rick Scott appointed a special prosecutor who charged Zimmerman with second-degree murder. The subsequent trial, which began in June 2013, became a focal point for national discussions regarding racial profiling and the application of self-defense statutes.

During the trial, the prosecution argued that Zimmerman had profiled Martin as a criminal, while the defense maintained that Zimmerman feared for his life during the struggle. On July 13, 2013, a jury of six women acquitted Zimmerman of both second-degree murder and manslaughter. In the immediate aftermath of the verdict, organizer Alicia Garza used the phrase “Black lives matter” in a social media post, which quickly evolved into a rallying cry. By the end of 2013, activists Patrisse Cullors, Alicia Garza, and Opal Tometi had established the Black Lives Matter Network to address systemic violence against Black communities.
