HI

I've got a sentence here:

The formulation of the Grand Council began, an institution which have an enormous impact on the future of imperial China.

This sentence gives me the doubt whether a definite article should be placed before the word IMPERIAL. yes or no, what's the difference?

I have this question also because, informally, we say Oxford University or Harvard University, without THE, as there are names preceding the word UNIVERSITY, but we often(or always?) put THE before an adjective when this adjective is the name of the university, like The Open University. Does it have anything to do with the sentence I have quoted? I tried in vain to find an answer in my books.
