Inspired by the scholars, activists, and everyday citizens who spoke out, marched, and protested against police killings of African-Americans, we present this collection of short essays that put Black lives at the center of our thinking about architecture and its history. Note to new readers: This project was published in early 2015, as a rapid response to the emergence of the Black Lives Matter movement. These articles are (sadly) sill relevant, and we hope they will be useful. We also wanted to direct readers to more recent texts that address the intersections of race, space, and activism.
