Diplomacy and wars
Naser al-Din was in Tabriz from Qajars tribe when he heard of his father's death in 1848, and he ascended to the Sun Throne with the help of Amir Kabir.
Naser al-Din had early reformist tendencies, but was dictatorial in his style of government. With his sanction, some Babis were killed after an attempt on his life. This treatment continued under his prime minister Amir Kabir, who even ordered the execution of the Báb – regarded as a manifestation of God to Bábí's and Bahá'ís, and to historians as the founder of the Bábí religion.
