Ides of March
A bad day for empires and emperors.
In 44BCE Julius Caesar was stabbed in the back by Senators. This was the first time, but definitely not the last time, this would happen.
In 1848 the Emperor of Austro-Hungary discovered he wasn’t the beloved leader of the Magyars, as revolution broke out in the Hungarian side of the Empire.
In 1917 Tsar Nicholas II decided that it was probably a good idea to hand the crown, mace, and scepter to his brother Michael, Prince of Lvov, who promptly turned it down. Unfortunately, Nicky wasn’t bright enough to get out of the country, and received the Julius treatment in the following year.
The 15th of March is a bad day to be Emperor.
