Anderson argues that the universal male suffrage of the Kaiserreich created a genuine "participatory political culture" (20) in the Empire. Anderson examines democratic source material such as petitions to highlight how Germans learned democracy by practicing it. The emergence of a democratic culture allowed large constituencies to emerge based around political ideals, communities which then fought with each other. Professionalization of politics also led to certain political standards, such as a toleration of opposing views and a rejection of violence, to develop. The stability which emerged allowed for the unequal system of Imperial Germany to continue without too much societal unrest.
