Due to conduct revolutionary propaganda among South Azerbaijan workers there was created the group of “Ictimaiyyun-e-amiyyun (social- democratic)-Adalet” in Baku. This group played an important role in the attraction of South Azerbaijan workers to class struggle of 1905-1907s.
In these years Tabriz organization and “Secret Union”, which was the leading organ of provincial Union of Azerbaijan, realized wide activity. Namely, by the leadership of this organ there occurred first military uprising on February 8, 1907, in Tabriz. Rebels took the reign in the city occupying all state institutions, military camps and gun stocks. The arrival of Azerbaijan representatives to Tehran and begining of their activity caused to the rise of national movement in the country and on the other side much more intensified confrontations between the reaction, led by Muhammedali Shah and democratic forces. Revolutionary uprisings in Tabriz, Tehran and other areas of the country made the Shah accept all demands. Much more essential ones among the accepted demands were the transformation of provincial Union of Azerbaijan into governing organ of this territory and the signition of provisions to the Law of October 7, 1907.
But after a while, on May-June of 1908, Shah administration again began to struggle against revolution. On June 23, by the order of Shah, Russian general Lyakhov shooted the building of Azerbaijan Union and its capital by artillery. At the result of it Mejlis was withdrawn, the revolutionists were severely punished. Despite of it, at the result of the activity of provincial Union in many cities, the revolutionary movement raised to its highest level, including Tabriz and this city became the centre of Iranian revolution.
