Al-Hakam was the second son of his father, his older brother having died at an early age. When he came to power, he was challenged by his uncles Sulayman and Abdallah, sons of his grandfather Abd ar-Rahman I. Abdallah took his two sons Ubayd Allah and Abd al-Malik to the court of Charlemagne in Aix-la-Chapelle to negotiate for aid. In the meantime Sulayman attacked Cordoba, but was defeated and driven back to Mérida where he was captured and executed. Abdallah was pardoned, but was forced to stay in Valencia. Al-Hakam spent much of his reign suppressing rebellions in Toledo, Saragossa and Mérida. The uprisings twice reached Cordoba. An attempt was made to dethrone Al-Hakam and replace him with his cousin Mohammed ibn al-Kasim, but the plot was discovered. On 16 November 806, 72 nobles and their attendants were massacred at a banquet, crucified and displayed along the banks of the riverGuadalquivir. Such displays of cruelty were not unusual during this period, with the heads of rebel leaders or Christian foes killed in expeditions to the north being put onshowat the gates of Cordoba. Following the rebellion in Cordoba, Al-Hakam established a personal bodyguard, the Al-Haras, led by the Visigothic leader of the Christians in Cordoba, the Comes Rabi, son of Theodulf, who also served as the Emir's tax collector. Rabi was later removed and executed by crucifixion for corruption. In 818 he crushed a rebellion led by clerics in the suburb of al-Ribad on the south bank of the Guadalquivir river. Some 300 notables were captured and crucified, while the rest of the inhabitants were exiled. Some moved to Alexandria in Egypt, some to Fez and Crete. Others joined the Levantine pirates.
