The answer is individual level of analysis. The individual level of analysis finds the cause of happenings in individual leaders or the immediate circle of decision makers within a specific country. It focuses on human actors on the world stage classifying the characteristics of human decision making. For example, the cause of World War I is from the specific leaders in power at that time. Kaiser Wilhelm II is deliberated to be the level from which the cause created. It may have been his need for power to hide a sense of subordination, or it may have been his incapability to understand the details of statecraft, the way Otto von Bismarck did. Or it may have been his notion about the monarchy and German destiny. All three possibilities are drawn from an individual level of analysis.
