"Crusader Kings 2" is a video game simulating the politicking, familial drama, and wars of medieval Europe. One game mechanic is "fabricating claims," where a skilled diplomat is sent to a land to forge documents prove that a noble has a rightful claim to it. Did this practice exist? How common?

Grammar error due to word limit. It should read, "documents proving that a noble..." and "How common was it?"
