Mohammad Ali Shah, was determined to crush the constitution. After several disputes with the members of the Majlis, in June 1908 he used his Russian-officered Persian Cossacks Brigade to bomb the Majlis building, arrest many of the deputies, and close down the assembly. Resistance to the shah, however, coalesced in Tabriz, Esfahan, Rasht, and elsewhere. In July 1909, constitutional forces marched from Rasht and Esfahan to Tehran, deposed the shah, and reestablished the constitution. The ex-shah went into exile in Russia.
