Long before the first African stepped foot on North American soil and long after the last slave ships plied the Atlantic Ocean, East Africa harbored its own dark trade. For centuries until the 1920s, Arab traders traveled into Africa’s heart to collect slaves for use both on African plantations and throughout the Middle East. Along the way, these slaves endured atrocities as cruel as many that happened in West Africa. Death marches to the coast for thousands of miles. Pain, hunger, exhaustion.
