This document provides an introduction to the journal article "Maritime Slavery" by Philip D. Morgan. It discusses how maritime slavery involved the movement of enslaved people as commodities across oceans, but also the roles that slaves played as sailors, pilots, cooks, and other maritime jobs. It explores how the maritime world provided some opportunities for slaves, such as potential wages, literacy, and more autonomy compared to plantation work, but also entailed risks and abuse from racial prejudice. The introduction sets the stage for examining slavery's role within diverse maritime contexts, including the Atlantic, Indian, and Pacific Oceans.
