Tsesarevich in the context of "Heir-apparent"

An heir apparent is a person who is first in the order of succession and cannot be displaced from inheriting by the birth of another person. A person who is first in the current order of succession but could be displaced by the birth of a more eligible heir is known as an heir presumptive.

Today these terms most commonly describe heirs to hereditary titles (e.g. titles of nobility) or offices, especially when only inheritable by a single person. Most monarchies refer to the heir apparent of their thrones with the descriptive term of crown prince or crown princess, but they may also be accorded with a more specific substantive title: such as Prince of Orange in the Netherlands, Duke of Brabant in Belgium, Prince of Asturias in Spain (also granted to heirs presumptive), or the Prince of Wales in England and Wales; former titles include Dauphin in the Kingdom of France, and Tsesarevich in Imperial Russia.

Nicholas II (Nikolai Alexandrovich Romanov; 18 May [O.S. 6 May] 1868 – 17 July 1918) was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland from 1 November 1894 until his abdication in 1917. His reign of over 22 years marked the final chapter of the Romanov dynasty, which had ruled Russia for more than three centuries. Nicholas married Alix of Hesse (later Alexandra Feodorovna), and they had five children: four daughters, Olga, Tatiana, Maria, and Anastasia, and a son, Alexei, the Tsesarevich.

Born in Tsarskoye Selo, Nicholas was the eldest son of Emperor Alexander III and Empress Maria Feodorovna. He was educated privately and trained for military service, but was widely considered ill-prepared for the demands of ruling a vast empire. As a constitutional monarch, he resisted political reform and retained autocratic control, despite the establishment of the Duma. His reign saw significant industrial growth and diplomatic engagement, including the Hague Conventions and the Anglo-Russian Convention of 1907, but was also marked by domestic unrest, military defeats, and widespread criticism.

Emperor Nicholas II abdicated the throne of the Russian Empire on the 2nd of March (O.S.) / 15th of March (N.S.) 1917, in the Russian city of Pskov, in the midst of World War I and the February Revolution. The Emperor renounced the throne on behalf of himself and his son, Tsarevich Alexei Nikolaevich, in favor of his brother Grand Duke Michael Alexandrovich. The next day the Grand Duke refused to accept the imperial authority, stating that he would accept it only if that was the consensus of democratic action by the Russian Constituent Assembly, which shall define the form of government for Russia. With this decision, the rule of the 300-year-old House of Romanov ended. Power in Russia then passed to the Russian Provisional Government, signaling victory for the February Revolution.

Alexei Nikolaevich (Russian: Алексей Николаевич Романов, romanized: Aleksey Nikolaevich Romanov; 12 August [O.S. 30 July] 1904 – 17 July 1918) was the last Russian tsesarevich (heir apparent). He was the youngest child and only son of Tsar Nicholas II and Tsarina Alexandra Feodorovna. He was born with haemophilia, which his parents tried treating with the methods of peasant faith healer Grigori Rasputin.

After the February Revolution of 1917, the Romanovs were sent into internal exile in Tobolsk, Siberia. After the October Revolution, the family was initially to be tried in a court of law, before the intensification of the Russian Civil War made execution increasingly favorable in the eyes of the Soviet government. With White Army soldiers rapidly approaching, the Ural Regional Soviet ordered the murder of Alexei, the rest of his family, and four remaining retainers on 17 July 1918. Rumors persisted for decades that Alexei had escaped his execution, with multiple impostors claiming his identity. Alexei's remains, along with those of his sister Maria (or Anastasia), were ultimately discovered in a secondary grave near the rest of the Romanov family in 2007. On 17 July 1998, the 80th anniversary of their execution, Alexei's parents, three of his sisters, and the four retainers, were formally interred in the Cathedral of St. Peter and Paul, while Alexei's and Maria's (or Anastasia's) bones remain in Russian state archives. The Romanov family was canonized as passion bearers by the Russian Orthodox Church in 2000.

Grand Duke George Mikhailovich of Russia (Russian: Георгий Михайлович Романов, romanized: Gěorgij Mihajlovič Romanov, also spelled Romanoff; German: Georg Michailowitsch Romanow; born 13 March 1981) is the heir apparent to Maria Vladimirovna, a claimant to the disputed Headship of the Imperial Family of Russia. He is the only child of Maria and her former husband, Prince Franz Wilhelm of Prussia. George's mother attributes to him the title of Tsesarevich and he bears the prefix of "Grand Duke" with the style of Imperial Highness which is still being questioned. As the son of a cadet member of the branch of the House of Hohenzollern which formerly ruled the German Empire and Kingdom of Prussia, he is also sometimes entitled "Prince of Prussia" with the style of Royal Highness.
