The world gasped in April 2015 as Baltimore erupted and Black Lives Matter activists, incensed by Freddie Gray's brutal death in police custody, shut down highways and marched on city streets. In The Black Butterfly - a reference to the fact that Baltimore's majority-Black population spreads out on both sides of the coveted strip of real estate running down the center of the city like a butterfly's wings - Lawrence T. Brown reveals that ongoing historical trauma caused by a combination of policies, practices, systems, and budgets is at the root of uprisings and crises in hyper-segregated cities around the country.

Putting Baltimore under a microscope, Brown looks closely at the causes of segregation, many of which exist in current legislation and regulatory policy. Drawing on social science research, policy analysis, and archival materials, Brown reveals the long history of racial segregation's impact on health, from toxic pollution to police brutality.

Brown offers a clear five-step plan for activists, nonprofits, and public officials to achieve racial equity. Brown offers up a wide range of innovative solutions to help heal and restore redlined Black neighborhoods, including municipal reparations. The Black Butterfly demonstrates that America cannot reflect that Black lives matter until we see how Black neighborhoods matter.
