Siege of Makkah (Second Fitnah)

After the death of the Umayyad Caliphate's founder Mu'awiya, the Islamic world was thrown into turmoil, although he had named his son Yazid I as his successor, this choice was not universally recognized, especially by the old Medinan elites, this led to the second Fitnah, which culminated in a 64-day siege of the holiest city in Islam, the sudden death of Yazid I and his sons, prompted the Umayyads to negotiate and acknowledged the defender of Makkah, ibn al-Zubayr as the Caliph, his authority remained nominal however.
