A crusader is a person who works hard or campaigns forcefully for a cause. Most crusaders advocate dramatic social or political change.
You can call a fierce champion for a cancer cure a crusader, and another kind of crusader could be an activist who works for school reform.

Crusader comes from crusade, which meant “campaign against a public evil” in the 18th century, but which earlier referred mainly to the religious-based military Crusades of the Middle Ages.
