Well, I wouldn't say he actually gave up his throne. It had more to do with the fact that he was dragged off it during the October 1917 Bolshevik revolution and had his throat cut or somesuch. He was dead, anyway, and so were all his family. Unfortunately, all the people got out of their revolution was Stalin, who made the Czar and any of his excesses look like a vacation in Hawaii. People feel sorry for the Jews. The Russians have had it at least as bad, if you ask me.
Czar Nicholas II
There was a revolution, the Russian Revolution of 1917; Czar Nicholas II was forcibly removed from power by the Bolsheviks and the Mensheviks.
The last Czar of Russian Empire was Nicholas II
Give up a throne
The last czar abdicated the throne on March 2, 1917, according to the Russian calendar then in use. In western countries, it was March 15, 1917
In 1855, Abraham Lincoln wrote that the Czar of Russia would more easily give up his throne than a slave owner would give up his slaves ( in the South ).
Nicholas II
March 15, 1917
abdicate
Belshazzar did not give up the throne of Babylon. It was taken from him when he was killed when Cyrus the Persian conqured the Babylonian Empire (Chaldean's)
King Henry VII did not "give up the throne." His reign ended when he died on 21 April 1509.
I believe that the year there was a Russian Czar was March 15, 1917 when Nicolas the II abdicated the throne.
