Following widespread bloody clashes and demonstrations and protests against the Regie Pact (Assignment of tobacco trade to the British Company by Iran’s king, Nasereddin Shah), Nasereddin Shah was compelled to annul that agreement and therefore the first comprehensive movement of the Iranian people against the despotic rule and the colonial agreement was victorious.. In this movement the Iranian women participated extensively. The Regie Pact was faced with strong opposition of the people. That is why Ayatollah Mirza Mohammad Hassan Shirazi, then supreme clergy, released the order of boycotting using tobacco by the people. This social opposition against despotic Nasereddin Shah and his treacherous agreements was so strong that even the women broke pipes in the royal court. The Tobacco Movement was the first extensive and pervasive movement against dictatorship and colonialism that was able to bring the women conspicuously to the movement scene and Predispose the condition for Constitutional Revolution. By setting fires on tobaccos and breaking pies, the women made the boycott victorious.
