By 1521, Luther's writings had made him famous, and in danger. He was ordered to appear before the Diet of Worms, a meeting of the empire's leaders led by the young Emperor Charles V. They told him to take back what he had written. Luther asked for one night to think.
The next day, April 18, 1521, he answered. He could not take it back unless Scripture or clear reasons proved him wrong. Going against his conscience was neither safe nor right. People remember the moment with the words “Here I stand, I can do no other.” The emperor let him travel home safely. But soon after, a new law made Luther an outlaw. Anyone could hurt him without being punished, and his books were to be burned.
