History
Presidential Term Limits and Political Succession Crises
Quick fact
Between 1960 and 2010, countries with presidential term limits were nearly twice as likely to experience a post-election crisis when the limit forced an incumbent out, compared to when the incumbent won or was not term-limited.
Why this is interesting
You might think term limits prevent leaders from holding too much power—but sometimes they cause exactly the crisis they were designed to avoid. Why would a rule meant to ensure peaceful change instead set the stage for chaos?

Understanding Presidential Term Limits and Political Succession Crises
Presidential term limits are constitutional rules that cap the number of terms a president can serve, typically two in many democracies. Their purpose is to prevent the danger of one person accumulating too much power over time, encouraging regular, peaceful rotation of leadership. However, these limits create a predictable moment every few years when the top office must change hands. A succession crisis happens when that moment goes badly: the rules for who takes over are unclear, the outgoing leader refuses to leave, or the incoming leader is not accepted. Think of a relay race where the baton must be passed—if the rules for the handoff are ambiguous or the runners don't cooperate, the team stumbles or even falls. In politics, that stumble can come from a loyalist challenging the result, a caretaker government overstaying its welcome, or a constitutional vacuum that leaves everyone unsure who is in charge.
A deeper explanation
The mechanism behind succession crises lies in the interplay of three factors: the clarity of succession rules, the stakes of the office, and the incentives of the actors. When term limits force an incumbent out, the office becomes open, raising the stakes for all players. If the constitution clearly designates who steps in (e.g., a vice president) and under what conditions, the transition can proceed smoothly. But many constitutions have gaps—such as what happens if the designated successor is also unable to serve, or if the election result is contested. These gaps create opportunities for political actors to exploit ambiguity. Moreover, term limits can paradoxically increase instability because an outgoing leader may fear future prosecution or loss of influence, making them reluctant to leave. Even with clear rules, a leader can use a compliant judiciary or legislature to change the rules, as seen in several African and Latin American countries where term limits were amended to allow reelection, prompting protests and coups. Thus, the mechanism of crisis is not the limit itself but the mismatch between the rule and the political reality—when constitutions fail to anticipate every contingency, or when actors value power more than the rule of law.
