Seyyed Hossein Emami (born 1303; died 1328) was a member of the Fadayan Islam group. Along with his brother Ali Mohammad, he killed Ahmad Kasravi with a knife on March 20, 1324, in the Palace of Justice, but he was released from prison at the insistence of the authorities at the time, including Abdul Hossein Hajir. Four years later, Seyyed Hossein Emami killed Hajir, who was the minister of the court, during the Muharram prayer ceremony of Sepahsalar Mosque on November 13, 1328, and was executed for the same crime.
