The Political Survival of Foreign Ministers

The survival of governments ultimately depends on the survival of its components. These components are politicians whose goal is to stay in office. There has been extensive research on the survival of leaders, but not on the survival of other politicians in government; and even less on how the survival of one affects the survival of the others. The purpose of this article is to take the first step in this direction by analyzing and precisely measuring the impact of the tenure of leaders on the tenure of foreign ministers. This article provides a systematic and formal investigation of the variables that affect the duration in office of foreign ministers. The investigation is based on a new data base on the tenure of more than 7,500 foreign ministers spanning three centuries. Although evidence shows that political institutions have significant impact on the tenure of foreign ministers, internal coalition dynamics such as affinity and loyalty toward a leader, uncertainty, and time dependence are better predictors of their political survival.
