Research the backstory and learn all that you can about your subject (person, event, thing, etc.).
Backstory is the events or history that has led to this moment in time.
Depending on your deadline, you can find background info in many places:

Government publications
Journal articles
Books
Documentary Films
Don't forget to evaluate the information that you find. Consider Who? What? When? Where? Why? How?
