Black Lives Matter movement founded

Alicia Garza wrote a 'love letter to Black people' on Facebook following George Zimmerman's acquittal in the Trayvon Martin case; Patrisse Cullors shared it with the hashtag #BlackLivesMatter; Opal Tometi amplified it online. This act launched one of the most consequential social movements of the 21st century, which mobilized millions worldwide and forced a global reckoning with systemic racism following the 2020 murder of George Floyd.
