In 1904, the Union of Liberation declared their intention to work for the establishment of constitutional government in Russia and organised a series of society banquets for the winter of 1904-05.
These banquets would allow leading liberals to meet under the pretence of a social event as anything too overtly political would gain the unwanted attention of the Okhrana.
Liberal groups in Russia by 1914 were becoming better organised and unified with clear objectives.
However, no liberal was talking about removing the Tsar.
They wanted a constitutional monarchy where the Tsar ruled but consulted the people's representatives.
Largely from middle class and noble backgrounds, liberals opposed violence or direct action.
In many cases, they feared rule by the people and were not connected to radical groups meaning that suppressing them would not stop other opposition.
