Firstly, what was the accurate birth date of Abdolrahim Talbof Tabrizi, who campaigned for freedom and the establishment of laws during the Constitutional Revolution? Secondly, what was the main reason for Talbof not attending the first term of the National Consultative Assembly as the representative of the people of Tabriz? The biography of Talbof Tabrizi is studied using historical records, especially his personal correspondence. Finally, it is concluded that Abdolrahim son of Sheikh Abutaleb ebne Alimorad - Known as Talbof - has been born in 1840 and his reason for refusing to attend the first term of the National Consultative Assembly was that he was considered irreligious by a number of the leaders of the Constitutional Revolution.
