Despite his father's staunch royalist tendencies and his ties to the royal court, young Teymourtash became an active member of the constitutional society headed by Malik al-Mutakallimin in Khorasan. While the rank and file of this particular society consisted mainly of lesser tradesman and poorer people, and included amongst its active membership very few educated notables, Teymourtash demonstrated his progressive tendencies by developing a strong affinity for the constitutional ideals and thrust of this gathering and assumed a leading role in the group.
