Question: What type of gesture does Donets-Krivoy Rog Soviet Republic and have in common?

full_context: Document 1: Treaty of San Stefano: The Preliminary Treaty of San Stefano (Russian: Сан-Стефанский мир; Peace of San-Stefano, Сан-Стефанский мирный договор; Peace treaty of San-Stefano, Turkish: "Ayastefanos Muahedesi" or "Ayastefanos Antlaşması") was a treaty between Russia and the Ottoman Empire signed at San Stefano, then a village west of Constantinople, on 3 March [O.S. 19 February] 1878 by Count Nicholas Pavlovich Ignatiev and Aleksandr Nelidov on behalf of the Russian Empire and Foreign Minister Safvet Pasha and Ambassador to Germany Sadoullah Bey on behalf of the Ottoman Empire. The treaty ended the Russo-Turkish War, 1877–78.
Document 2: Reinsurance Treaty: The Reinsurance Treaty, (June 18, 1887), a secret agreement between Germany and Russia arranged by the German chancellor Otto von Bismarck after the German-Austrian-Russian "Dreikaiserbund" or League of the Three Emperors, collapsed in 1887, because of competition between Austria-Hungary (Franz Joseph I) and Russia (Alexander III) for spheres of influence in the Balkans. The treaty provided that each party would remain neutral if the other became involved in a war with a third great power, though this would not apply if Germany attacked France or if Russia attacked Austria. Bismarck showed the Russian ambassador the text of the German-Austrian alliance of 1879 to drive home the last point. Germany paid for Russian friendship by agreeing to the Russian sphere of influence in Bulgaria and Eastern Rumelia (now part of southern Bulgaria) and by agreeing to support Russian action to keep the Black Sea as its own preserve. When the treaty was not renewed in 1890, a Franco-Russian alliance rapidly began to take shape.
Document 3: Separate peace: The phrase "separate peace" refers to a nation's agreement to cease military hostilities with another, even though the former country had previously entered into a military alliance with other states that remain at war with the latter country. For example, at the start of World War I (1914–1918), Russia was a member, with the United Kingdom and France, of the Triple Entente, which went to war with the Central Powers formed by Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. After the fall of Russian monarch Nicholas II and the rise to power of the Bolsheviks, Russia defaulted on its commitments to the Triple Entente by signing a separate peace with Germany and its allies in 1917. This armistice was followed on 3 March 1918 by the formal signing of the Treaty of Brest-Litovsk.
Document 4: Occupation of Turkish Armenia: The occupation of Turkish Armenia by the Russian Empire during World War I began in 1915 formally ended by the Treaty of Brest-Litovsk. It was sometimes referred to as the "Republic of Van" by Armenians, because the occupation imitated in Van. Aram Manukian of Armenian Revolutionary Federation was the "de facto" head until July 1915. It was briefly referred to as "Free Vaspurakan". After a setback beginning in August 1915, it was re-established in June 1916. From December 1917, it was under Transcaucasian Commissariat, with Hakob Zavriev as the Commissar, and during the early stages of the establishment of First Republic of Armenia, it was included with other Armenian National Councils in a briefly unified Armenia.
Document 5: Chinese Soviet Republic: The Chinese Soviet Republic (CSR), also known as the Soviet Republic of China or the China Soviet Republic, is often referred to in historical sources as the Jiangxi Soviet (after its largest component territory, the Jiangxi-Fujian Soviet). It was established in November 1931 by future Communist Party of China leader Mao Zedong, General Zhu De and others, and it lasted until 1937. Discontiguous territories included the Northeastern Jiangxi, Hunan-Jiangxi, Hunan-Hubei-Jiangxi, Hunan-Western Hubei, Hunan-Hubei-Sichuan-Guizhou, Shaanxi-Gansu, Szechuan-Shensi, Hubei-Henan-Anhui, Honghu and Haifeng-Lufeng Soviets.
Document 6: Treaty of Moscow (1921): The Treaty of Moscow or Treaty of Brotherhood (Turkish: "Moskova Antlaşması" , Russian: Московский договор ) was a peace treaty between the Grand National Assembly of Turkey (TBMM), under the leadership of Mustafa Kemal Atatürk, and the Russian SFSR, under the leadership of Vladimir Lenin, signed on 16 March 1921. Neither the Republic of Turkey nor the Soviet Union was established at the time. The internationally recognized Turkish government at the time was that of Sultan Mehmed VI, but it was not party to the Treaty of Moscow. The latter had signed the Treaty of Sèvres, which had been repudiated by the Turkish National Movement.
Document 7: Treaty of Brest-Litovsk: The Treaty of Brest-Litovsk was a peace treaty signed on 3 March 1918 between the new Bolshevik government of Soviet Russia and the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire), that ended Russia's participation in World War I. The treaty was signed at Brest-Litovsk (Polish: "Brześć Litewski" ; since 1945 Brest), after two months of negotiations. The treaty was agreed upon by the Bolshevik government under threat of further advances by German and Austrian forces. According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Triple Entente alliance.
Document 8: Soviet westward offensive of 1918–19: The Soviet westward offensive of 1918–1919 was part of the general move of the Russian Soviet Federative Socialist Republic into areas abandoned by the Ober Ost garrisons that were being withdrawn to Germany following that country's defeat in World War I. The initially successful offensive against Estonia ignited the Estonian War of Independence which ended with the Soviet recognition of Estonia. The war against Latvia and Lithuania was more successful for the Soviets, and resulted in the Latvian Socialist Soviet Republic and Lithuanian Soviet Socialist Republics being established. In Belarus the Belarusian People's Republic was conquered and the Socialist Soviet Republic of Byelorussia proclaimed.
Document 9: Bavarian Soviet Republic: The Bavarian Soviet Republic (German: "Bayerische Räterepublik" ) was the short-lived unrecognised socialist state in Bavaria during the German Revolution of 1918–19. It took the form of a workers' council republic. Its name is variously rendered in English as the Bavarian Council Republic or the Munich Soviet Republic (the German name "Räterepublik" means a republic of councils or committees; council or committee is also the meaning of the Russian word "soviet") after its capital of Munich. It was established in April 1919 following the demise of Kurt Eisner's People's State of Bavaria and sought independence from the also newly-proclaimed Weimar Republic. However, it was overthrown less than a month later by elements of the German Army and the paramilitary "Freikorps".
Document 10: North Caucasian Soviet Republic: North Caucasian Soviet Republic (Russian: Се́веро-Кавка́зская Сове́тская Респу́блика , "Severo-Kavkazskaya Sovetskaya Respublika") (July 7–December, 1918) was a territory in the North Caucasus established to consolidate Soviet power during the Russian Civil War. A republic of the Russian SFSR, it was created by merging the Kuban-Black Sea Soviet Republic, the Stavropol Soviet Republic, and the Terek Soviet Republic. Its capital was Yekaterinodar; however, on August 17, 1918 Yekaterinodar was taken by Denikin's Volunteer Army, and the capital was moved to Pyatigorsk.
Document 11: Treaty of Sèvres: The Treaty of Sèvres (French: "Traité de Sèvres" ) was one of a series of treaties that the Central Powers signed after their defeat in World War I. Hostilities had already ended with the Armistice of Mudros. The treaty was signed on 10 August 1920, in an exhibition room at the Manufacture nationale de Sèvres porcelain factory in Sèvres, France.
Document 12: Donetsk People's Republic: The Donetsk People's Republic (DPR or DNR) (Russian: Доне́цкая Наро́дная Респу́блика , "Donétskaya Naródnaya Respúblika"; ] , Ukrainian: Донецька Народна Республіка , "Donets'ka Narodna Respublika ") is a self-proclaimed state in the Donetsk Oblast of Ukraine. It has been recognized only by the partially recognized Republic of South Ossetia. It receives humanitarian and military backing from Russia. The Ukrainian government has designated it as a terrorist organization and it is at war with Ukraine, alongside the Luhansk People's Republic (LPR). It formed an unrecognized confederation of Novorossiya, referencing the corresponding historical region and its name with the also unrecognized LPR until its 20 May 2015 suspension, and since February 2015 has postured itself as the successor to the historic Donetsk–Krivoy Rog Soviet Republic. Along with the Luhansk People's Republic and the Autonomous Republic of Crimea, the Donetsk People's Republic is considered one of three temporarily occupied territories of Ukraine as a result of Russian military intervention of 2014.
Document 13: Donets-Krivoy Rog Soviet Republic: The Donetsk–Krivoy Rog Soviet Republic (Russian: Донецко-Криворожская советская республика ) was a self-declared Soviet republic of the Russian SFSR founded on 12 February 1918. The republic claimed "self-determined" territories in treaties of Brest-Litovsk; it was founded three days after the government of Ukraine signed the treaty with Germans, which recognised the borders of Ukrainian People's Republic, within which the Donetsk-Krivoy Rog Soviet Republic was located. On 29 March 1918 it became a republic within Ukrainian Soviet Republic, where it was merged with Ukrainian People's Republic of Soviets (capital in Kharkov, founded 25 December 1917) and Odessa Soviet Republic (founded 1 March 1918), until the last was fully occupied by the German forces according to treaties of Brest-Litovsk.
Document 14: Lithuanian Soviet Socialist Republic (1918–19): The Lithuanian Soviet Socialist Republic (LSSR) was a short-lived Soviet republic declared on December 16, 1918 by a provisional revolutionary government led by Vincas Mickevičius-Kapsukas. It ceased to exist on February 27, 1919 when it was merged with the Socialist Soviet Republic of Byelorussia to form the Lithuanian–Byelorussian Soviet Socialist Republic (Litbel). While efforts were made to represent the LSSR as a product of a socialist revolution supported by local residents, it was largely a Moscow-orchestrated entity created to justify the Lithuanian–Soviet War. As a Soviet historian, adhering to official propaganda, put it: "The fact that the Government of Soviet Russia recognized a young Soviet Lithuanian Republic unmasked the lie of the USA and British imperialists that Soviet Russia allegedly sought rapacious aims with regard to the Baltic countries." Lithuanians generally did not support Soviet causes and rallied for their own national state, declared independent on February 16, 1918, by the Council of Lithuania.
Document 15: Central Powers: The Central Powers (German: "Mittelmächte" ; Hungarian: "Központi hatalmak" ; Turkish: "İttifak Devletleri" or "Bağlaşma Devletleri" ; Bulgarian: Централни сили "Tsentralni sili" ), consisting of Germany, Austria-Hungary , the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance (German: "Vierbund" ) – was one of the two main factions during World War I (1914–18). It faced and was defeated by the Allied Powers that had formed around the Triple Entente. The Powers' origin was the alliance of Germany and Austria-Hungary in 1879. The Ottoman Empire and Bulgaria did not join until after World War I had begun, although the Ottoman Empire retained close relations with both Germany and Austria-Hungary since the beginning of the 20th century.
