Slavery was abolished in the British Empire in 1833, thirty years before the Emancipation Proclamation in the United States. But even after they freed their slaves, the sugar plantation owners were desperate to find cheap labor to cut cane and process sugar. So the British owners looked to another part of the empire—India—and recruited thousands of men and women, who were given five-year contracts and a passage back. For a person from India, going overseas was not a simple matter. Once you crossed the "black water" of the surrounding oceans, you were said to have "gone to tapu." You no longer had any place in your village and could not be accepted back until you went through a special ceremony. Leaving India truly meant giving up your home; yet for some—for my family—that was their only chance for a better life.
