Black Lives Matter (BLM) is an international activist movement, originating in the African-American community, that campaigns against violence and systemic racism toward black people. BLM regularly holds protests against police killings of black people and broader issues of racial profiling, police brutality, and perceived 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. The originators of the hashtag and call to action, Alicia Garza, Patrisse Cullors, and Opal Tometi, expanded their project into a national network of over 30 local chapters between 2014 and 2016. The overall Black Lives Matter movement, however, is a decentralized network and has no formal hierarchy.
Since the Ferguson protests, participants in the movement have demonstrated against the deaths of numerous other African Americans by police actions or while in police custody. In the summer of 2015, Black Lives Matter activists became involved in the 2016 United States presidential election. (Wikipedia)
