Before I answer this question, let me examine the word “rivalry” in the context of competition among different regions. The reason rivalry exists primarily because there is a lot of pride and emotional investment individual residents have toward the region they live in. It is because there is a strong “local love” for his or her town or city or region that if there is a cause for comparison, such as professional sports teams, economy, landscape, etc., people will get up in arms touting their own region is better.
