August 5 – Iranian Constitution Day A Historic Date for Iran.

August 5, 1906, marks the anniversary of the promulgation of the Constitutional Decree, a pivotal date in Iran's contemporary history. This decree resulted from a series of protests and street clashes led by the clergy, bazaar merchants, and intellectuals of the time.
The Decree of Muzaffar al-Din Shah
This day commemorates the moment when Muzaffar al-Din Shah Qajar signed the decree establishing the National Consultative Assembly (Majlis). The signing of this document represented acceptance of the demands of the constitutional movement's protesters and marked the end of absolute monarchy, introducing popular participation in government affairs. For this reason, it is known as the "Constitutional Decree."
120 Years of Parliamentarism
On this basis, parliament and national legislation for regulating people's affairs and political renewal in Iran have a history of one hundred and twenty years. During this period, numerous socio-political movements arose to preserve the popular character of Iranian government: the oil nationalization movement, the 15 Khordad movement, and finally the Islamic Revolution.
The Iranian People's Continued Commitment
Iranians have always devoted their efforts to protecting, strengthening, and completing legislative institutions, political participation, and civic and citizenship rights, deciding their own future.
