The search is on for the Clotilda, whose survivors formed their own community after emancipation. Archaeologists have conducted a comprehensive search in Alabama's Mobile River for a shipwreck thought to be the last slave ship to arrive in America. In 1860, the Clotilda brought just over 100 people from West Africa to the states. They were enslaved for only a few years before being emancipated and forming their own community near Mobile. Africatown was the only known community in the U.S. founded by Africans who arrived through the Transatlantic Slave Trade. Today, Africatown is just a shadow of what it once was. And the descendants of the Clotilda, which was burned shortly after its arrival in Alabama, are hoping that the discovery of the ship could draw more attention to their unique community, the story of their ancestors and the legacy of slavery.
