The recent police killings of Michael Brown and Eric Garner — and the failure to indict the officers responsible — have ignited people across the US to declare that black lives matter. People are demanding an end to the violence being inflicted on black communities, and a movement is building, with significant leadership by young black organizers.

One important way to take action in this moment is to contribute financially to support racial justice movement-building. To make the change we seek, we will need thriving, well-funded organizations based in communities of color who deeply understand the problems and needed solutions.

Now is the time to show our solidarity with communities who have been living with and resisting the injustices of racism, police brutality, and other forms of oppression for far too long.

Sign on to the pledge if you commit to fund at least one additional racial justice organization before the end of 2015, or to increase your giving to a racial justice group you already support. You can pledge publicly or anonymously.
