The Treaty of Warsaw (also the Polish-Ukrainian or Petliura-Piłsudski Alliance or Agreement) of April 1920 was a military-economical alliance between the Second Polish Republic, represented by Józef Piłsudski, and the Ukrainian People's Republic, represented by Symon Petliura, against Bolshevik Russia. The treaty was signed on 21 April 1920, with a military addendum on 24 April.


The alliance was signed during the Polish-Soviet War, just before the Polish Kiev Offensive. Piłsudski was looking for allies against the Bolsheviks and hoped to create a Międzymorze alliance; Petliura saw the alliance as the last chance to create an independent Ukraine.

The treaty had no permanent impact. [1] The Polish-Soviet War continued and the territories in question were distributed between Russia and Poland in accordance with the 1921 Peace of Riga. Territories claimed by the Ukrainian national movement were split between the Ukrainian SSR in the east and Poland in the west (Galicia and part of Volhynia).


The Polish leader Józef Piłsudski was trying to create a Poland-led alliance of East European countries, the Międzymorze federation, designed to strengthen Poland and her neighbors at the expense of the Russian Empire, and later of the Russian SFSR and the Soviet Union. [2] [3] His plan was however plagued with setbacks, as some of his planned allies refused to cooperate with Poland, and others, while more sympathetic, preferred to avoid conflict with the Bolsheviks. [4] But in April 1920, from a military standpoint, Polish army needed to strike at the Soviets, to disrupt their plans for an offensive of their own. [5] Piłsudski also wanted an independent Ukraine to be a buffer between Poland and Russia rather than seeing Ukraine again dominated by Russia right at the Polish border. [6] Piłsudski, who argued that "There can be no independent Poland without an independent Ukraine", may have been more interested in Ukraine being split from Russia than he was in Ukrainians' welfare. [7] As such, Piłsudski turned to Petliura, whom he originally had not considered high on his planned allies list. [8]

A Ukrainian delegation could not gain recognition for Ukraine as an independent state at the Treaty of Versailles at the end of the First World War, and the Ukrainian dream of independence was also plagued with setbacks, with Ukrainian lands becoming a warzone between various local and foreign factions vying for their control. The Ukrainian People's Republic, led by Petliura, suffered mounting attacks on its territory since early 1919, and by April 1920 most of Ukrainian territory was outside its control. [9]

In such conditions, Józef Piłsudski had little difficulty in convincing Petliura to join the alliance with Poland despite recent conflict between the two nations that had been settled in favour of Poland the previous year. [4]

The treaty was signed on 21 April in Warsaw [8] (it was signed at night 01:40 LST from 21 onto 22, but it was dated as of 21 April 1920). [10] In exchange for agreeing to a border along the Zbruch River, recognizing the recent Polish territorial gains in western Ukraine (obtained by the Poland's defeating the Ukrainian attempt to create another Ukrainian state in Galicia, territories with mixed Ukrainian-Polish population) as well as the western portions of Volhynian Governorate, Kholm Governorate, and other territories [10] (Article II), [4] [11] Poland recognized the Ukrainian People's Republic as an independent state (Article I) with borders as defined by Articles II and III and under ataman Petliura's leadership. [8] [12]

A separate provision in the treaty prohibited both sides from concluding any international agreements against each other (Article IV). [13] Ethnic Poles within the Ukrainian border, and ethnic Ukrainians within the Polish border, were guaranteed the same rights within their states (Article V). [14] Unlike their Russian counterparts, whose lands were to be distributed among the peasants, Polish landlords in Ukraine were accorded special treatment [13] until a future legislation would be passed by Ukraine that would clarify the issue of Polish landed property in Ukraine (Article VI). [8] Further, an economic treaty was drafted, significantly tying Polish and Ukrainian economies; Ukraine was to grant significant concessions to the Poles and the Polish state. [4] [8]

The treaty was followed by a formal military alliance signed by general Volodymyr Sinkler and Walery Sławek on 24 April. Petliura was promised military help in regaining the control of Bolshevik-occupied territories with Kiev, where he would again assume the authority of the Ukrainian People's Republic. [5] The Ukrainian republic was to subordinate its military to Polish command and provide the joint armies with supplies on Ukrainian territories; the Poles in exchange promised to provide equipment for the Ukrainians. [4] [8]

On the same day as the military alliance was signed (24 April), Poland and UPR forces began the Kiev Operation , aimed at securing the Ukrainian territory for Petliura's government thus creating a buffer for Poland that would separate it from Russia. Sixty-five thousand Polish and fifteen thousand Ukrainian soldiers [15] took part in the initial expedition. After winning the battle in the south, the Polish General Staff planned a speedy withdrawal of the 3rd Army and strengthening of the northern front in Belarus where Piłsudski expected the main battle with the Red Army to take place. The Polish southern flank was to be held by Polish-allied Ukrainian forces under a friendly government in Ukraine. [16]

For Piłsudski, this alliance gave his campaign for the Międzymorze federation the legitimacy of joint international effort, [8] secured part of the Polish eastward border, and laid a foundation for a Polish dominated Ukrainian state between Russia and Poland. [4] For Petliura, this was a final chance to preserve the statehood and, at least, the theoretical independence of the Ukrainian heartlands, even while accepting the loss of Western Ukrainian lands to Poland. [17]

Both Piłsudski and Petliura were criticized by other factions within their governments and nations. Piłsudski faced stiff opposition from Dmowski's National Democrats who opposed Ukrainian independence; Petliura, in turn, was criticized by many Ukrainian politicians for entering a pact with the Poles and giving up on Western Ukraine. [18] Mykhailo Hrushevsky, the highly respected chairman of the Central Council, also condemned the alliance with Poland and Petliura's claim to have acted on the behalf of the UPR. [18] In general, many Ukrainians viewed a union with Poles with great suspicion, [6] [17] especially in the view of historically difficult relationships between the nations, and the alliance received an especially dire reception from Galicia Ukrainians who viewed it as their betrayal; [19] their attempted state, the West Ukrainian People's Republic, had been defeated by July 1919 and was now to be incorporated into Poland. The Western Ukrainian political leader, Yevhen Petrushevych, who expressed fierce opposition to the alliance, left for exile in Vienna. The remainder of the Ukrainian Galician Army, the Western Ukrainian state's defence force, still counted 5,000 able fighters though devastated by a typhus epidemic, [20] joined the Bolsheviks on 2 February 1920 as the transformed Red Ukrainian Galician Army. [21] [22] Later, the Galician forces would turn against the Communists and join Petliura's forces when sent against them, resulting in mass arrests and disbandment of the Red Galician Army. [23]

On April 26, in his "Call to the People of Ukraine", Piłsudski assured that "the Polish army would only stay as long as necessary until a legal Ukrainian government took control over its own territory". [24] Despite this, many Ukrainians were just as anti-Polish as anti-Bolshevik, [6] and resented the Polish advance, [5] which many viewed as just a new variety of occupation [25] considering previous defeat in the Polish-Ukrainian War. [26] Thus, Ukrainians also actively fought the Polish invasion in Ukrainian formations of the Red Army. [22] Some scholars stress the effects of Soviet propaganda in encouraging negative Ukrainian sentiment towards the Polish operation and Polish-Ukrainian history in general. [5]

The alliance between Piłsudski and Petliura resulted in 15,000 allied Ukrainian troops supporting Poles at the beginning of the campaign, [27] increasing to 35,000 through recruitment and desertion from the Soviet side during the war. [27] This number, however, was much smaller than expected, and the late alliance with Poland failed to secure Ukraine's independence, as Petliura did not manage to gather any significant forces to help his Polish allies. [28]

On 7 May, during the course of the Kiev Offensive, the Pilsudski-Petliura alliance took the city. Anna M. Cienciala writes: "However, the expected Ukrainian uprising against the Soviets did not take place. Ukraine was ravaged by war; also, most of the people were illiterate and had not developed their own national consciousness. Finally, they distrusted the Poles, who had formed a large part of the landowning class in Ukraine up to 1918." [5]

The divisions within the Ukrainian factions themselves, with many opposing Poles just as they opposed the Soviets, further reduced the recruitment to the pro-Polish Petliurist forces. In the end, Petliurist forces were unable to protect the Polish southern flank and stop the Soviets, as Piłsudski hoped; Poles at that time were falling back before the Soviet counteroffensive and were unable to protect Ukraine from the Soviets by themselves. [28]

The Soviets retook Kiev in June. Petliura's remaining Ukrainian troops were defeated by the Soviets in November 1920, [29] and by that time the Poles and the Soviets had already signed an armistice and were negotiating a peace agreement. After the Polish-Soviet Peace of Riga next year, Ukrainian territory found itself split between the Ukrainian SSR in the east, and Poland in the west (Galicia and part of Volhynia). Piłsudski felt the agreement was a shameless and short-sighted political calculation. Allegedly, having walked out of the room, he told the Ukrainians waiting there for the results of the Riga Conference: "Gentlemen, I deeply apologize to you". [30] [31] Over the coming years, Poland would provide some aid to Petliura's supporters in an attempt to destabilize Soviet Ukraine (see Prometheism), but it could not change the fact that Polish-Ukrainian relations would continue to steadily worsen over the interwar period. [19] [32] One month before his death Piłsudski told his aide: "My life is lost. I failed to create the free from the Russians Ukraine". [33]

They were squeezed between the Red Russians of Lenin and Trotsky in the north-east, White Russians of Denikin in south-east and the Poles in the West. Death were looking into their eyes. And not only to the people but to the nascent Ukrainian state. Therefore, the chief ataman Petliura had no choice but to accept the union offered by Piłsudski, or, as an alternative, to capitulate to the Bolsheviks, as Volodymyr Vinnychenko or Mykhailo Hrushevsky did at the time or in a year or two. The decision was very hurtful. The Polish Szlachta was a historic enemy of the Ukrainian people. A fresh wound was bleeding, the West Ukrainian People's Republic, as the Pilsudchiks were suppressing the East Galicians at that very moment. However, Petliura agreed to peace and the union, accepting the Ukrainian-Polish border, the future Soviet-Polish one. It's also noteworthy that Piłsudski also obtained less territories than offered to him by Lenin, and, in addition, the war with immense Russia. The Dnieper Ukrainians then were abandoning their brothers, the Galicia Ukrainians, to their fate. However, Petliura wanted to use his last chance to preserve the statehood - in the union with the Poles. Attempted, however, without luck."

The operation led to a Soviet counteroffensive resulting in the creation of the short-lived Galician Soviet Socialist Republic, and ended amicably with the formal Peace of Riga of 1921.

Polish–Ukrainian War 1918-1919 conflict between the Second Polish Republic and West Ukrainian Peoples Republic

The Polish–Ukrainian War of November 1918 and 1919 was a conflict between the Second Polish Republic and Ukrainian forces. The conflict had its roots in ethnic, cultural and political differences between the Polish and Ukrainian populations living in the region. The war started in Eastern Galicia after the dissolution of the Austro-Hungarian Empire and spilled over into Chełm Land and Volhynia (Wołyń) regions formerly belonging to the Russian Empire, which were both claimed by the Ukrainian State and the Ukrainian People's Republic.

Causes of the Polish–Soviet War

During the Polish–Soviet War of 1919-1921, Soviet Russia and Soviet Ukraine were in combat with the re-established Second Polish Republic and the newly established Ukrainian People's Republic. Both sides aimed to secure territory in the often disputed areas of the Kresy, which make up today's Ukraine and parts of modern-day Belarus, in the context of the fluidity of borders in Central and Eastern Europe in the aftermath of World War I and the breakdown of the Austrian, German, and Russian empires. The first clashes between the two sides occurred in February 1919, but full-scale war did not break out until the following year. Especially at first, neither Soviet Russia, embroiled in the Russian Civil War, nor Poland, still in the early stages of state re-building, were in a position to formulate and pursue clear and consistent war aims.

The Polish–Soviet war erupted in 1919 in the aftermath of World War I. The root causes were twofold: a territorial dispute dating back to Polish–Russian wars in the 17–18th centuries; and a clash of ideology due to RSFSR's goal of spreading communist rule further west, to Europe. At that time both countries had just undergone transition: in 1918 Poland reclaimed independence after 123 years of partitions. In 1917 the October Revolution replaced the liberal, democratic Provisional Government, that had previously displaced the Tsar in Russia, with Soviet rule. The war ended with the Treaty of Riga in 1921, which settled the border issue and regulated Polish-Soviet relations until the German-Soviet invasion of Poland in 1939.

Directorate of Ukraine

The Directorate, or Directory was a provisional collegiate revolutionary state committee of the Ukrainian People's Republic, initially formed on November 13–14, 1918 during a session of the Ukrainian National Union in rebellion against Skoropadsky's regime. During the overthrow of Pavlo Skoropadsky it was named as the Executive Council of the State Affairs. Its authority was extended by the Labor Congress of Ukraine on January 23–28, 1919.

Związek Walki Czynnej was a Polish secret military organization founded in June 1908 in Lwów by Józef Piłsudski, Marian Kukiel, Kazimierz Sosnkowski and Władysław Sikorski, all members of the Combat Organization of the Polish Socialist Party's Revolutionary Faction.

The Polish–Romanian Alliance was a series of treaties signed in the interwar period by the Second Polish Republic and the Kingdom of Romania. The first of them was signed in 1921 and, together, the treaties formed a basis for good foreign relations between the two countries that lasted until World War II began in 1939.

Various factions fought over Ukrainian territory after the collapse of the Russian Empire following the Russian Revolution of 1917 and after the First World War ended in 1918, resulting in the collapse of Austria-Hungary, which had ruled Ukrainian Galicia. The crumbling of the empires had a great effect on the Ukrainian nationalist movement, and in a short period of four years a number of Ukrainian governments sprang up. This period was characterized by optimism and by nation-building, as well as by chaos and civil war. Matters stabilized somewhat in 1921 with the territory of modern-day Ukraine divided between Soviet Ukraine and Poland, and with small ethnic-Ukrainian regions belonging to Czechoslovakia and to Romania.

Ukrainian War of Independence

The Ukrainian War of Independence, a period of sustained warlike conflict, lasted from 1917 to 1921 and resulted in the establishment and development of a Ukrainian republic, most of which was later absorbed into the Soviet Union as the Ukrainian Soviet Socialist Republic of 1922–1991.

History of the Ukrainian minority in Poland

The history of the Ukrainian minority in Poland dates back to the Late Middle Ages, preceding the 14th century Galicia–Volhynia Wars between Casimir III the Great of Poland, and Liubartas of Lithuania. Following the extinction of the Rurikid dynasty in 1323, the Polish Kingdom extended further east in 1340 to include the lands of Przemyśl and in 1366, Kamianets-Podilskyi. After the Union of Lublin (1569), principalities of Galicia and Western Volhynia became, what is known as, the Ruthenian Voivodeship of the Polish Crown, while the rest of Red Ruthenia together with Kiev came under Lithuanian control. The Polish borders reached as far east as Zaporizhia, and Poltava.

The Ukrainian People's Army, also known as the Ukrainian National Army (UNA) was the Army of the Ukrainian People's Republic (1917-1921). They were often quickly reorganized units of the former Imperial Russian Army or newly formed volunteer detachments that later joined the national armed forces. The army lacked a certain degree of uniformity, adequate leadership to keep discipline and morale. Unlike the Ukrainian Galician Army, the Ukrainian People's Army did not manage to evolve a solid organizational structure, and consisted mostly of volunteer units, not regulars.

The Ukrainian People's Republic, or Ukrainian National Republic, a predecessor of modern Ukraine, was declared on 10 June 1917 following the February Revolution in Russia. It initially formed part of the Russian Republic, but proclaimed its independence on 25 January 1918. During its short existence the republic went through several political transformations - from the socialist-leaning republic headed by the Central Council with its general secretariat to the national republic led by the Directorate and by Symon Petliura. Between April and December 1918 the Ukrainian People's Republic did not function, having been overthrown by the Ukrainian State of Pavlo Skoropadsky. From late 1919 the UNR operated as an ally of the Second Polish Republic, but by then the state de facto no longer existed in Ukraine. The 18 March 1921 Treaty of Riga between the Second Polish Republic, Soviet Russia and of Soviet Ukraine sealed the fate of the Ukrainian People's Republic.

Ukrainian–Soviet War war (1917–1921) between the Ukrainian Peoples Republic and the Bolsheviks, won by the latter, resulting in the establishment of the Ukrainian SSR

The Ukrainian–Soviet War is the term commonly used in post-Soviet Ukraine for the events taking place between 1917–21, nowadays regarded essentially as a war between the Ukrainian People's Republic and the Russian Soviet Republic. The war ensued soon after the October Revolution when Lenin dispatched the Antonov's expeditionary group to Ukraine and Southern Russia.
