Ali ibn Yahya

Ali inherited the throne from his father, Yahya ibn Tamim, in 1116.^[1] He planned to launch attacks on the Italo-Norman Kingdom of Sicily, and sought the aid of the Almoravids for the purpose.^[1] This led to a series of clashes with the Normans in the decades after his death and culminating in the capture of the Zirid capital, Mahdia, in 1148.^[1] Ali's son, Abu'l-Hasan al-Hasan, was thus the last Zirid ruler.^[1]
