[10] The uprising began on April 5, 1920, and was preceded by protests and speeches by some members of the Tabriz Committee of the Azerbaijani Democratic Party against the policies of the central government and the 1919 agreement.
[11] The statement was issued by the party on that Thursday: The libertarians of Tabriz are excited by the reactionary tendencies that have manifested in a series of anti-constitutional actions by the local governments, and have risen up with the intention of protesting strongly and sedately.
The libertarians of Tabriz declare that the whole point of their program is to obtain a total and complete assurance that government officials respect the free regime of the country and sincerely follow the constitutions.
[2]The uprising did not have a cohesive organization and the division of responsibilities was not clear, and it was mostly run individually and with the help of some members of the Democratic Party of Tabriz, such as Ismail Nobari[12] and Mohammad Agha Hariri,[13][14] and Khiabani himself.
After the uprising began, a committee called the "Board of Directors of the Assemblies" formed and handed over government offices and appointed a supervisor for Nazmiyeh (law enforcement).
Nazmiyeh and gendarmerie forces were handed over, but the Cossack Brigade was still under the command of the provincial ruler Abdol Majid Mirza, taking orders from him and Tehran.
On September 13, 1920, the Cossack forces and some gendarmerie agents, with the prior coordination and order of Mehdi Qoli Hedayat and under the command of Brigadier general Hashemi,[16] attacked the building of the uprising headquarters.
He, who tried to raise awareness and enlighten the minds of the people with his speeches, neglected to equip and arm the masses, and the popular support was weakened for various reasons.
