The Black Lives Matter movement started in 2012 after the killing of Trayvon Martin by George Zimmerman. Patrisse Cullors created the #BlackLivesMatter hashtag on social media to connect people across the country. Hundreds of African Americans have continued to lose their lives due to racism and police brutality even after high-profile cases like Trayvon Martin's. The killing of George Floyd sparked the largest protests in the movement's history against systemic racism and police violence. Today, organizations, companies, and influencers are working to combat racism through donations, staff changes, and promoting diversity.
