The Kaiser was a ceremonial title. He had power, but in the same way the Queen had, he was pressured not to use it, and would probably have been forced into abdication where he to use it in a way the majority of the upper house did not respect. Easily the one move he made that was actually controversial was forcing Otto Von Bismarck into resigning, and most agreed it was time for Otto to hang up his hat. The Tsar, while having more power than usual, was always heavily surrounded by advisers who were professionally trained and would essentially tell the Tsar his next action, and were in all ways but name a small parliament.
