Read the passage from Sugar Changed the World.

In the 1930s, reporters spread out across the American South to capture the voices of history. Some African Americans who had been born as slaves were still alive, and could describe how they had lived sixty years earlier. Through their words we can finally begin to hear about sugar slavery from those who lived it.

Ellen Betts, who grew up as a slave on a sugar plantation in Louisiana, recalled that they worked "hour in, hour out, the sugar cane fields sure stretch from one end of the earth to the other." Ceceil George remembered that she "come up in hard times—slavery times." "Every body worked, young, an ole’, if yo’ could carry two or three sugar cane yo’ worked. Sunday, Monday, it all de same . . . it like a heathen part o’ de country." She meant that in other states slaves got Sunday off to worship God. Not in Louisiana: There, sugar was god, and work was the only religion.
