A dynastic crisis occurs when a ruling family faces challenges that threaten its power and stability. This can happen due to issues like succession disputes, lack of heirs, or external pressures from rival factions. Such crises often lead to political instability, civil wars, or the rise of new powers. Historically, dynastic crises have been significant in shaping nations. For example, the Wars of the Roses in England were fueled by competing claims to the throne, leading to a prolonged period of conflict. Similarly, the Ming Dynasty in China faced a crisis when internal strife weakened its authority, paving the way for the Qing Dynasty to rise.
