Although a younger son of Moḥammad Shāh, Nāṣer al-Dīn was named heir apparent through the influence of his mother. Serious disturbances broke out when he succeeded to the throne on his father’s death in 1848, but these were quelled through the efforts of his chief minister, Mīrzā Taqī Khān. Under Taqī Khān’s influence, Nāṣer al-Dīn began his rule by instituting a series of needed reforms. Taqī Khān, however, was later forced from power by his enemies, who included Nāṣer al-Dīn’s mother, and was disgraced, imprisoned, and finally murdered. In 1852 an attempt was made on Nāṣer al-Dīn’s life by two Bābīs (members of a religious sect considered heretical); he responded with a fierce, cruel, and prolonged persecution of the sect.
