In October 1905, the Tsar proclaimed the October Manifesto in response to the revolution that had become wildly out of hand. This appeased many of the protestors, mainly the middle classes, and it was enough to break the unity of the revolution so that government troops could put an end to the disturbances. But before long, the Fundamental Laws had been passed and these clearly showed that the Duma was not to be the force for democracy that the people of Russia had expected. In time, the Duma became a key factor in the 1917 Revolution in which the Tsar was forced to abdicate.
