They use them to bold for titles also they use them for words people might not know.
I know its not much but hopefully you got a little help
What the section above basically says is:
<em>They offered him a crown, but he pushed it away with his hand, and then his people started shouting.</em>
These lines are from Julius Caesar, a tragedy written by Shakespeare. It retells the historical events of Julius Caesar's life, politics, and ultimately his death, having been betrayed and murdered by one of his closest friends, Brutus. Casca, who says these words, is one of the people who actually killed Caesar.
The play would be helpful here.
