WAR. What is it good for? Human history is filled with senseless violence and usually, it is justified by "noble" notions like freedom or modernisation, or straight-up greed for oil, land or gold. But sometimes, humans resort to murdering one another over the most trivial of things, giving the term "senseless violence" a literal meaning.

A good example could be when two medieval city-states in northern Italy – Modena and Bologna – supposedly fought a war due to the theft of an ordinary unremarkable wooden bucket.
