Read the passage from Sugar Changed the World.

Mohandas K. Gandhi (later known as the Mahatma or Great One) was born in India to a traditional Hindu family. When he was given the opportunity to study law in England, he faced the same problem as the indentured sugar workers: He would lose caste if he crossed the black water. His family arranged a special ceremony that allowed him to make the trip without giving up his place in society. Thus, in 1894, freshly educated in England, Gandhi made a second journey. He began practicing law in Natal, a region in what is now South Africa. He moved there because many Indians were already in Natal, laboring as indentured sugar workers.

One day, Gandhi later explained, "a man in tattered clothes, headgear in hand, two front teeth broken and his mouth bleeding, stood before me trembling and weeping." The indentured worker, whose name was Balasumdaram, had been badly beaten by his employer. Gandhi knew that Balasumdaram was trapped. For no matter how poorly he had been treated by his boss, if he left the plantation, he could be prosecuted and jailed. Gandhi saw indenture for what it was: "almost as bad as slavery. Like the slave the indentured labourer was the property of his master."
