I'm writing a paper about the interpretation of a treaty and I want to include a chapter on the historical background to explain why a certain article must be interpreted a certain way. In this context should I say the historical background for Treaty X, the historical background of Treaty X or use a different preposition entirely?
I checked both phrases on google and each had several million hits. Background of had more, but if the sense changes somewhat with the choice of preposition then that doesn't necessarily mean anything.
