What was the short term significance of the 1905 revolution on Russia?

The essence of the question focusses on the short-term impact of the 1905 revolution with particular focus on the significance of such an event. Identifying the necessary and relevant factual knowledge is an important part of such question, demonstrating a precision with which to answer accurately. The question requires attention focussing on the year and its immediate aftermath. Particular detail to the widespread civil disruption and concessions made by Tsar Nicholas II and Sergei Witte in the October Manifesto, along with the fundamental laws issued afterward, ushered in somewhat of a constitutional experiment which should be the focus of the response to such a question. Explicitly focusing on the immediate year(s) is the point of the task, identifying those years in isolation to what occurred later in 1917 and the two revolutions that took place. Being able to analyse the events of 1905 in isolation suggests a broader strain of thought rather than simply acknowledging them as a stepping stone toward the February and October revolutions of 1917. The significance of the events is debatable, with historians such as Orlando Figes and Hans Rogger concluding that the autocracy was doomed by its very nature despite acknowledgment that the reforms of Witte, and later Stolypin, could have endeavoured toward a constitutional monarchy. Although there is no specific answer the response should focus on the importance of the aftermath of the 1905 revolution with particular attention to the social and political changes which occurred as a result.
