Black Lives Matter (BLM) is an international activist movement, originating in the African-American community, that campaigns against violence toward black people. BLM regularly organizes protests around the deaths of black people in killings by law enforcement officers, and broader issues of racial profiling, police brutality, and racial inequality in the United States criminal justice system.
In 2013, the movement began with the use of the hashtag #BlackLivesMatter on social media, after the acquittal of George Zimmerman in the shooting death of African-American teen Trayvon Martin. Black Lives Matter became nationally recognized for its street demonstrations following the 2014 deaths of two African Americans: Michael Brown, resulting in protests and unrest in Ferguson, and Eric Garner in New York City.
