Why was Báb killed?
As a result of Báb’s new claim and the events of Badasht, Nasser al-Din Shah who was the crown prince at that time, summoned Báb to Tabriz and questioned him about his claim. His attempts to answer the questions was futile, after 11 strokes to his leg, he repented of his claims (as the Báb or Imam Mahdi). He was not executed because of these claims which was declared mentally unstable. However because of the magnitude of the nationwide chaos which he brought to Iran, he was executed later.
