I've received a number of emperor's portraits, that's why decided to combine them in one post.
Alexander II (Alexander the Liberator ) (1818-1881)
He was a liberal emperor, who accomplished the Emancipation reform of 1861 in Russia - in my opinion, one of the greatest reforms in the history of Russia. He is also know as to have been assassinated. That was a very unusual, even an incredible thing, because in the course of Russian history Tsars and Emperors were regarded as very reliable persons, given to rule the state by the God and even were sometimes called as "Tsar-father".
Alexander III (1845-1894)
A son of Alexander II. He was the next emperor after his father.
From History lessons I remember he was a very strong man. Once the Imperial train got into an accident, due to the crash a carriage roof collapsed and Alexander III had to hold its remains till the children ran out of the carriage. However this situation influenced his health and he died soon after it.
Nicholas II (1868-1918)
The last Russian emperor. So he is one of the most well-know, talked about emperors of all Russian emperors.
By a belief he knew the date of his death (which also was the year of the falling of emperor power in Russia), which had been predicted 100 years before it (approx. in 1817-18) to his ancestor Alexander I. That emperor ordered to conserve the prediction and to open it only in 100 years.
