Why didn't liberalism take root in Russia between 1815 and 1917?

It was almost impossible for Russia to have any type of liberal movement because of the tsar and multiple communist movements taking place. The government was very extreme and most “liberal” movements or strikes were forced to be eliminated. Russia did at one point (I think that this was when Alexander I was tsar) seem to try and blend both autocracy and liberalism, but obviously this didn’t work as the Dumas were overpowered. The government just didn’t work for a liberal movement even though one tried to take place.
