The hierarchy rivalry theory is based on the perception of social reality as a rivalry between associations and rivalry of systems of norms. The state constitution is a collection of tops of hierarchies. A constitution can be changed for various reasons – sometimes the change is an attempt to transform reality, and sometimes it results from the ruling party’s attempt to maintain power. A constitutional change may be a revolution, understood as a process within the hierarchy, or an invasion resulting from external influence. The importance of the influence of ideology, but also of associations, on changes to the constitution should be recognized.
