How did Martin Luther?

The question makes no sense at all... How did he what? But here's who he was if that's what you meant: He was a German man who opposed the Roman Catholic ideas. He thought that they were making too much money and lying about things like selling indulgences (things that buy you time out of hell which wasn't necessarily true) and that the Pope was having sexual relationships with women when he wasn't supposed to. (It says in the Bible) So he protested and that's where the Protestant term comes from.
Next time be clearer on your answer. It is NOT hard to type a sentence properly!
