Abd Allah ibn al-Zubayr
Following a period of unrest during the Second Fitna in 679 CE (60 AH), Husayn ibn 'Ali was martyred at Karbala and Yazid assumed unchecked control for the next three years. In 682 CE (63 AH), Abd Allah ibn al-Zubayr declared himself Caliph of Mecca and the people of Medina swore allegiance to him. This led to an eight-year-long period of economic distress for the city. In 692 CE (73 AH), the Umayyads regained power and Medina experienced its second period of huge economic growth. Trade improved and more people moved into the city. The banks of Wadi al-'Aqiq were now lush with greenery. This period of peace and prosperity coincided with the rule of 'Umar ibn Abdulaziz, who many consider to be the fifth of the Rashidun.
