Two skeletal remains found near Yekaterinburg, Russia are confirmed by Russian scientists to be the remains of Alexei and Anastasia, two of the children of the last Tsar of Russia, whose entire family was executed at Yekaterinburg by the Bolsheviks.

Alexei Nikolaevich (Russian: ) (12 August [O.S. 30 July] 1904 17 July 1918) of the House of Romanov, was the last Tsesarevich (heir apparent to the throne of the Russian Empire).

He was the youngest child and only son of Emperor Nicholas II and Empress Alexandra Feodorovna. He was born with haemophilia, which his parents tried treating with the methods of a peasant faith healer named 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 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.

Alexei is sometimes known to Russian legitimists as Alexei II, as they do not recognize the abdication of his father in favor of his uncle Grand Duke Michael as lawful.

Yekaterinburg ( yih-KAT-ər-in-burg; Russian: Екатеринбург, IPA: [jɪkətʲɪrʲɪnˈburk]), alternatively romanized Ekaterinburg, formerly known as Sverdlovsk (Russian: Свердло́вск, IPA: [svʲɪrˈdlofsk], 1924–1991), is the largest city and the administrative centre of Sverdlovsk Oblast and the Ural Federal District, Russia. The city is located on the Iset River between the Volga-Ural region and Siberia, with a population of roughly 1.5 million residents, up to 2.2 million residents in the urban agglomeration. Yekaterinburg is the fourth-largest city in Russia, the largest city in the Ural Federal District, and one of Russia's main cultural and industrial centres. Yekaterinburg has been dubbed the "Third capital of Russia", as it is ranked third by the size of its economy, culture, transportation and tourism.Yekaterinburg was founded on 18 November 1723 and named after the Russian emperor Peter the Great's wife, who after his death became Catherine I, Yekaterina being the Russian form of her name. The city served as the mining capital of the Russian Empire as well as a strategic connection between Europe and Asia. In 1781, Catherine the Great gave Yekaterinburg the status of a district town of Perm Province, and built the historical Siberian Route through the city. Yekaterinburg became a key city to Siberia, which had rich resources. In the late 19th century, Yekaterinburg became one of the centres of revolutionary movements in the Urals. In 1924, after the Russian SFSR became a part of the Soviet Union, and a socialist state, the city was named Sverdlovsk after the Bolshevik leader Yakov Sverdlov. During the Soviet era, Sverdlovsk was turned into an industrial and administrative powerhouse. In 1991, after the dissolution of the Soviet Union, the city returned to its historical name.

Yekaterinburg is one of Russia's most important economic centres and was one of the host cities of the 2018 FIFA World Cup. The city is currently experiencing an economic and population boom, which resulted in some of the tallest skyscrapers of Russia being located in the city. Yekaterinburg is home to the headquarters of the Central Military District of the Russian Armed Forces, as well as the presidium of the Ural Branch of the Russian Academy of Sciences, and will be the host city of the 2023 Summer Universiade.
