An often-overlooked 1968 social justice movement confronted poverty head-on and reimagined American activism, but you've probably never heard of it. The Smithsonian's traveling exhibition Solidarity Now! 1968 Poor People’s Campaign looks closely at the nearly six-week-long protest, which took place in a constructed "Resurrection City" in DC and drew attention to the impact of poverty on Americans. Everyone from rural Appalachians to residents of Puerto Rico and Native communities showed up for demonstrations and demands for jobs, living wages, access to health care, and more. Organized by Martin Luther King Jr. and Ralph Abernathy, the Poor People's Campaign was the "first large-scale, nationally organized demonstration to take place after King’s death." Head to this exhibition to learn more about it through photographs, oral histories, and political ephemera. by Lindsay Costello
