West Ukrainian People's Republic in the context of "Flag of Ukraine"

The Ukrainian People's Republic (UPR) was a short-lived state in Eastern Europe. Prior to its proclamation, the Central Council of Ukraine was elected in March 1917 as a result of the February Revolution, and in June, it declared Ukrainian autonomy within Russia. Its autonomy was later recognized by the Russian Provisional Government. Following the October Revolution, the Central Council of Ukraine denounced the Bolshevik seizure of power and proclaimed the Ukrainian People's Republic with a territory including the area of approximately eight Russian imperial governorates (Kiev, Volhynia, Kharkov, Kherson, Yekaterinoslav, Poltava, Chernigov and Podolia). It formally declared its independence from Russia on 22 January 1918.

During its short existence, the republic went through several political transformations – from the socialist-leaning republic headed by the Central Council of Ukraine with its general secretariat, to the socialist republic led by the Directorate and by Symon Petliura. Between April and December 1918, the socialist authority of the Ukrainian People's Republic was suspended, having been overthrown by the pro-German Ukrainian State of Pavlo Skoropadskyi, who was elected as the Hetman of Ukraine by a congress of peasants. After the collapse of the Ukrainian State, the Ukrainian People's Republic declared its unification with the West Ukrainian People's Republic in January 1919. After the Polish–Ukrainian War, it signed an alliance with the Second Polish Republic. On 10 November 1920, the state lost the remainder of its territory to the Bolsheviks. The Peace of Riga on 18 March 1921 between Poland, Soviet Russia (acting also on behalf of Soviet Belarus), and Soviet Ukraine sealed the fate of the Ukrainian People's Republic.

The Unification Act (Ukrainian: Акт Злуки, romanized: Akt Zluky, IPA: [ˈɑkt ˈzlukɪ]; or Велика Злука, Velyka Zluka, IPA: [ˈwɛlɪkɐ ˈzlukɐ]) was an agreement signed by the Ukrainian People's Republic and the West Ukrainian People's Republic in Sophia Square in Kyiv on 22 January 1919. Since 1999, it is celebrated every year as the Day of Unity of Ukraine to commemorate the signing of the treaty; it is a state holiday in Ukraine, though not a public holiday.

The Polish–Ukrainian War, from November 1918 to July 1919, was a conflict between the Second Polish Republic and Ukrainian forces (both the West Ukrainian People's Republic and the Ukrainian People's Republic).

The conflict had its roots in ethnic, cultural, and political differences between the Polish and Ukrainian populations living in the region, as Poland and both Ukrainian republics emerged from the collapse of the Russian and Austrian empires.

The Lwów pogrom (Polish: pogrom lwowski, German: Lemberger Pogrom, Ukrainian: львівський погром) was a pogrom perpetrated by Polish soldiers and civilians against the Jewish population of the city of Lviv, West Ukrainian People's Republic (then taken by Poland). It happened on 21–23 November 1918, during the Polish–Ukrainian War that followed World War I.

During three days of unrest in the city, an estimated 52–150 Jewish residents were killed, and hundreds were injured. Non-Jewish casualties were also reported. They were mainly Ukrainian, and they might have outnumbered the Jewish fatalities. The total number of victims was reported to be 340. Roughly 1,600 people, including some soldiers, were arrested by Polish authorities during and after the pogrom. Seventy-nine of them were tried by Polish military courts, with 44 of them being convicted. Although three of the pogromists were executed, most of the others received lenient sentences, ranging from 10 days to 18 months.

Ivano-Frankivsk (Ukrainian: Івано-Франківськ, IPA: [iˈwɑno frɐnˈkiu̯sʲk] ), formerly Stanyslaviv, Stanislav and Stanisławów, is a city in western Ukraine. It serves as the administrative centre of Ivano-Frankivsk Oblast as well as Ivano-Frankivsk Raion within the oblast. Ivano-Frankivsk also hosts the administration of the Ivano-Frankivsk urban hromada. Its population is 238,196 (2022 estimate), 227,827 (2024 estimate).

Built in the mid-17th century as a fortress of the Polish Potocki family, Stanisławów was annexed to the Habsburg Empire during the First Partition of Poland in 1772, after which it became the property of the State within the Austrian Empire. Throughout this time, it was within the Kingdom of Galicia and Lodomeria. The fortress was slowly transformed into one of the most prominent cities at the foothills of the Carpathian Mountains. After World War I, for several months, it served as a temporary capital of the West Ukrainian People's Republic. Following the Peace of Riga in 1921, Stanisławów became part of the Second Polish Republic. After the Soviet invasion of Poland at the onset of World War II, the city was annexed by the Soviet Union, only to be occupied by Nazi Germany two years later. With the liberation of Soviet Ukraine in 1944 and the shifting of borders, the city remained part of the Ukrainian SSR and was renamed in 1962 after Ivan Franko. With the fall of the Soviet Union in 1991, the city become part of newly-independent Ukraine.
