I want to know the answer to the following question:
Which war transformed many colleges, including Northwestern?
All the background I'm provided with is that "Relations between Evanston and Northwestern were strained throughout much of the post-war era because of episodes of disruptive student activism, disputes over municipal zoning, building codes, and law enforcement, as well as restrictions on the sale of alcohol near campus until 1972.". Is that enough to answer the question?
