October Manifesto
In June, 1905, the Potemkin Mutiny took place and industrial workers all over Russia went on strike. In October, 1905, the railwaymen went on strike which paralyzed the whole Russian railway network. Later that month, Leon Trotsky and other Mensheviks established the St. Petersburg Soviet. Over the next few weeks over 50 of these soviets were formed all over Russia.
Witte, the new Chief Minister, advised Nicholas II to make concessions. He eventually agreed and published the October Manifesto. This granted freedom of conscience, speech, meeting and association. He also promised that in future people would not be imprisoned without trial. Finally he announced that no law would become operative without the approval of the State Duma.
As the Duma was only a consultative body, many Russians felt that this reform did not go far enough. Leon Trotsky and other revolutionaries denounced the plan. In December, 1905, Trotsky and the rest of the executive committee of the St. Petersburg Soviet were arrested. Others followed and gradually Nicholas II and his government regained control of the situation.

Through all these horrible days, I constantly met Witte. We very often met in the early morning to part only in the evening when night fell. There were only two ways open; to find an energetic soldier and crush the rebellion by sheer force. That would mean rivers of blood, and in the end we would be where had started. The other way out would be to give to the people their civil rights, freedom of speech and press, also to have laws conformed by a State Duma - that of course would be a constitution. Witte defends this very energetically.
Almost everybody I had an opportunity of consulting, is of the same opinion. Witte put it quite clearly to me that he would accept the Presidency of the Council of Ministers only on the condition that his programme was agreed to, and his actions not interfered with. We discussed it for two days and in the end, invoking God's help I signed. This terrible decision which nevertheless I took quite consciously. I had no one to rely on except honest Trepov. There was no other way out but to cross oneself and give what everyone was asking for.
