Yakov Sverdlov in the context of "Alexander Beloborodov"

Yekaterinburg (/jɪˈkætərɪnbɜːrɡ/ yih-KAT-ər-in-burg; Russian: Екатеринбург, IPA: [jɪkətʲɪrʲɪnˈburk] ), alternatively romanized as Ekaterinburg and formerly known as Sverdlovsk (Свердловск IPA: [svʲɪrˈdlofsk] ; 1924–1991), is a 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 most populous 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 Orthodox name of Catherine I (born Marta Helena Skowrońska), the wife of Russian Emperor Peter the Great. 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 founded the Soviet Union, the city was renamed Sverdlovsk after the Bolshevik leader Yakov Sverdlov. During the Soviet era, Sverdlovsk was turned into an industrial and administrative powerhouse. On 23 September 1991 the city returned to its historical name.

Jewish Bolshevism, also Judeo–Bolshevism, is an antisemitic and anti-communist conspiracy theory that claims that the Russian Revolution of 1917 was a Jewish plot and that Jews controlled the Soviet Union and international communist movements, often in furtherance of a plan to destroy Western civilization. It was one of the main Nazi beliefs that served as an ideological justification for the German invasion of the Soviet Union and the Holocaust.

After the Russian Revolution, the antisemitic canard was the title of the pamphlet The Jewish Bolshevism, which featured in the racist propaganda of the anti-communist White movement forces during the Russian Civil War (1918–1922). During the 1930s, the Nazi Party in Germany and the German American Bund in the United States propagated the antisemitic theory to their followers, sympathisers, and fellow travellers. Nazi Germany used the trope to implement anti-Slavic policies and initiate racial war against the Soviet Union, portraying Slavs as inferior humans controlled by Jews to destroy Aryan people.

The Donetsk–Krivoy Rog Soviet Republic or Donetsk–Kryvyi Rih Soviet Republic (Russian: Донецко-Криворожская советская республика, romanized: Donetsko-Krivorozhskaya sovyetskaya respublika; Ukrainian: Донецько-Криворізька Радянська Республіка, romanized: Donetsko-Kryvorizka Radianska Respublika) was a self-declared Soviet republic of the Ukrainian People's Republic of Soviets proclaimed on 12 February 1918. It was founded three days after the government of the Ukrainian People's Republic (UPR) signed its Treaty of Brest-Litovsk with the Central Powers, which recognised the borders of the UPR. Lenin did not support the creation of the entity and neither did Sverdlov. Some other Bolsheviks like Elena Stasova, however, sent a telegraph of best wishes.

On 3 March 1918 a separate Treaty of Brest-Litovsk was signed between Soviet Russia and the Central Powers (Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria), by which Russia withdrew from World War I. The Article III of the treaty stated that "the territories lying to the west of the line agreed upon by the contracting parties which formerly belonged to Russia, will no longer be subject to Russian sovereignty" and "the future status of these territories will be determined in agreement with their population".

Nikolay Nikolayevich Krestinsky (Russian: Никола́й Никола́евич Крести́нский; 13 October 1883 – 15 March 1938) was a Soviet Bolshevik revolutionary and politician who served as the Responsible Secretary of the Communist Party of the Soviet Union.

Born in Mogilev to a Ukrainian family, Krestinsky studied law at Saint Petersburg Imperial University, where he embraced revolutionary politics. He became a member of the Russian Social Democratic Labour Party (RSDLP) in 1903, and two years later he supported Vladimir Lenin's Bolshevik faction following the RSDLP split. Repeatedly arrested, he was exiled to the Urals in 1914, shortly before the outbreak of the First World War. After the 1917 February Revolution brought an end to the monarchy, Krestinsky led the Bolsheviks in Yekaterinburg before returning to Petrograd. He was named People's Commissar for Finance and elected to the first Politburo. After the death of Yakov Sverdlov, Krestinsky also served as Responsible Secretary of the Russian Communist Party.
