Sometimes what you’re looking for is right in your own backyard. For what you’re interested in, I highly recommend that you take a look at Connecticut College in New London.
Why Conn College? Because Peace & Conflict Resolution is one of those majors that you don’t study in isolation. It involves understanding cultures, their history, their economies, their politics. It involves learning conflict resolution strategies and how to apply them both locally and globally.
A few years ago, Conn College completely rethought their approach to the liberal arts. They developed an approach called Connections through which students with the help of their advisors develop plans to integrate their entire program for all 4 years so that everything you do is “connected”. They developed a second approach called Pathways in which you develop theme(s) that you pursue for 4 years and build your program around. These are really decision making tools to help you find ways to have your academic experience match your aspirations.
Peace & Conflict is one of their “Pathways”. You can build your 4 years of study around this theme in whatever way makes sense to you. And you’re not alone in doing it. You have an advisor to mentor you and help with your decisions.
I have a feeling that you’d find at Conn College what you’re looking for and that they’d love to have you. The good news is that you can drive there from anywhere in Connecticut - and get back home easily whenever you want to.
