Political succession varies across systems, influencing stability and governance continuity. In democracies, elections typically determine leadership changes, ensuring accountability to the electorate. Conversely, authoritarian regimes may rely on appointment or hereditary succession, often leading to a lack of legitimacy. Transitional processes, like coups or revolutions, can also define succession in volatile environments. Understanding these dynamics is essential for predicting political stability and assessing the legitimacy of leadership, as they profoundly affect the nation's governance and citizen trust.
