Shortly after the Union won the Civil War in 1865, a union major general issued an order: “The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free.” June 19, known as Juneteenth, has long been celebrated by African Americans. But in 2020, in the thick of the Covid-19 pandemic and the protests that followed the murder of George Floyd, Juneteenth took the internet by storm. Marketplace’s Lily Jamali spoke with Brandon Ogbunu, professor in the Department of Ecology and Evolutionary Biology at Yale, who wrote about that moment for WIRED back then. He revisited what was happening at that time a year before Juneteenth became a national holiday.
