When Alexander II was assassinated, his son Alexander III took over. Unfortunately, he had very different ideas from his father that were pretty much the opposite of his dad's. Also, after Alexander II was assassinated, the revolutionaries thought that his death was the beginning of a new uprising of their power and ideas. On the contrary, Alexander III was absolutely against the ideas of the revolutionaries and had the people in charge of his fathers assassination hanged. The remaining people of the radical group that assassinated Alexander II plotted to kill Alexander III, but were found out and hanged. Also, I don't quite understand why Alexander III believed in ideas that would only continue to slow Russia and keep it in the dark.
