The Czar's full name and title is: the Saint Czar Nicholas Alexandrovich Romanov II of Russia, Grand Duke of Finland, and titular King of Poland. Alexandrovich is a Russian custom in which the middle name is derived from the name of the father, and ends with either the suffix -vich for men or -aevna for women. For example, Nicholas was named AlexandroVICH after his father, Alexander. His daugthers received their middle name NikolAEVNA from their father's name, Nicholas.
The Tzar, also spelt Tsar or Czar, is, or was the ruler of Russia. The name is derived from Caesar, as is Kaiser in german. The last Tsar was Nicholas II, who was overthrown in 1917 in the Russian Revolution.
There were two czars (or 'tsars,' depending on the system of transliteration) by the name of Nicholas. Nicholas I, whose reign lasted from 1825-1855, was the son of Tsar Pavel (also Romanized as "Paul") I. Nicholas II, the last ruling tsar, who abdicated the throne in favor of the provisional government in 1917, was the son of Tsar Alexander III.
There were two Tsars of that name on Russian Throne: Nicholas I (1825 - 1856) and the very last Russian Tsar Nicholas II. Their common mistake was a firm believe in divine origin of king's power and in supremacy of Orthodox form of Christianity over any other variation of Christian religion.
She was the last legitimate Czarina of Russia, and somewhat oddly was born German. Her maiden name was the most Germanic-sounding Alexandra Von Hess, she dropped this, of course, on marrying Czar Nicholas, then Crown Prince. Olga ( l895-l9l8) was born while Nicholai was still Crown Prince, not yet Czar of all the Russias. Of couse she ws the mother of Olga, Tatiana, Maria, and Anastasia as welll as the new ( and very vulnerable) Hemophiliac crown prince- Alexis. there is no way Alexis could have survicvd the revolution. ( Blood hazard). so it goes.
The last name of the Russian tsar before the Russian Revolution was Romanov.
