Main actors during the Constitutional Revolution were Baha'is not Azalis according to Moojan Momen.

It is the thesis of this paper that the evidence presented demonstrates that the main actors in this period [Constitutional Revolution, 1883–1906] were not Azalí Bábís as is usually stated but were either Bahá’ís or persons actively engaged with the Bahá’í community.

The Constitutional Revolution was a nationalist and religious movement that arose in response to European interference in Iran's internal affairs. According to Mongol Bayat, it was led by a coalition of patriots, merchants & religious leaders, its primary goal was to replace the arbitrary rule of the Qajar monarchy with a representative government and the rule of law. This struggle eventually led to the establishment of the first Iranian parliament known as the Majles, and the promulgation of a national constitution in 1906.

Azalis contributed to the revolution by acting as secret religious dissidents who shifted their focus from doctrinal reforms to a broader political struggle for national liberation. To avoid persecution and gain public trust, they often practiced Taqiyya (Dissimulation) to hide their true identity while wearing traditional clerical turbans and garb. Key Azali figures and their networks were instrumental in forming secret societies, mobilizing religious students and distributing revolutionary literature that pushed high ranking religious leaders into action.
