Globalization, risk-taking and violence: too much too soon in the late Roman Republic and pre-Renaissance Italian cities

Past research has found that globalization and political violence have been linked in both modern and less modern times. Normally, groups that have been disadvantaged or displaced by globalization are seen as responsible for these outbreaks of violence. In the case of the Late Republic of Rome and medieval Italy before the Renaissance, violence was actually prompted by major increases in wealth among those who benefited when control of the political system became much more valuable. The increased value raised the stakes of political control and underlay the resulting higher levels of violence.
