May Alexander II reign long and well

Alexander II was Russian Emperor from 1855/56-1881. He was most famous for emancipating the serfs, but he did introduce a whole host of other liberal reforms - the Zemstvo system, his judicial, education, military and financial reforms. However, he was assassinated by the "People's Will" terrorist organisation on the 1st March 1881. But, on that same day, he signed the Loris-Melikov constitution - the first step to a constitutional monarchy. I made this timeline with one simple Point of Divergence - the assassination failed.
