First Partition of Poland in the context of "Polish–Soviet War"

Lviv (/ləˈviːv/ lə-VEEV or /ləˈviːf/ lə-VEEF; Ukrainian: Львів [ˈlʲviu̯] ; Polish: Lwów [ˈlvuf] ; see below for other names) is the largest city in western Ukraine, as well as the fifth-largest city in Ukraine, officially with a population of 723,403 (2025 estimate). It serves as the administrative centre of Lviv Oblast and Lviv Raion, and is one of the main cultural centres of Ukraine. Lviv also hosts the administration of Lviv urban hromada. It was named after Leo I of Galicia, the eldest son of Daniel, King of Ruthenia.

Lviv (then Lwów) emerged as the centre of the historical regions of Red Ruthenia and Galicia in the 14th century, superseding Halych, Chełm, Belz, and Przemyśl. It was the capital of the Kingdom of Galicia–Volhynia from 1272 to 1340, when it went to King Casimir III the Great of Poland in a war of succession. In 1356, Casimir the Great granted it town rights. From 1434, it was the regional capital of the Ruthenian Voivodeship in the Kingdom of Poland. In 1772, after the First Partition of Poland, the city became the capital of the Habsburg semi-autonomous Polish-dominated Kingdom of Galicia and Lodomeria. From 1918, between the wars, the city was the centre of the Lwów Voivodeship in the Second Polish Republic. There it flourished in culture, industry and academia such as the Lwów School of Mathematics, the Lwów Historical School (Polish: lwowska szkoła historyczna) and the Lwów School of Economics. After the German-Soviet invasion of Poland in 1939, the massacre of Lwów professors took place, and Lwów was eventually annexed by the Soviet Union.

The Partitions of Poland were three partitions of the Polish–Lithuanian Commonwealth that took place between 1772 and 1795, toward the end of the 18th century. They ended the existence of the state, resulting in the elimination of sovereign Poland and Lithuania for 123 years. The partitions were conducted by the Habsburg monarchy, the Kingdom of Prussia, and the Russian Empire, which divided up the Commonwealth lands among themselves progressively in the process of territorial seizures and annexations.

The First Partition was decided on August 5, 1772, after the Bar Confederation lost the war with Russia. The Second Partition occurred in the aftermath of the Polish–Russian War of 1792 and the Targowica Confederation when Russian and Prussian troops entered the Commonwealth and the partition treaty was signed during the Grodno Sejm on January 23, 1793 (without Austria). The Third Partition took place on October 24, 1795, in reaction to the unsuccessful Polish Kościuszko Uprising the previous year. With this partition, the Commonwealth ceased to exist.

The Russo-Turkish War of 1768–1774 was a major armed conflict that saw Russian arms victorious against the Ottoman Empire. Russia's victory brought the Yedisan between the rivers Bug and Dnieper, and Crimea into the Russian sphere of influence. Though a series of victories accrued by the Russian Empire led to substantial territorial conquests, including direct conquest over much of the Pontic–Caspian steppe, less Ottoman territory was directly annexed than might otherwise be expected due to a complex struggle within the European diplomatic system to maintain a balance of power that was acceptable to other European states and avoided direct Russian hegemony over Eastern Europe.

Nonetheless, Russia took advantage of the weakened Ottoman Empire, the end of the Seven Years' War, and the withdrawal of France from Polish affairs to assert itself as one of the continent's primary military powers. The war left the Russian Empire in a strengthened position to expand its territory and maintain hegemony over the Polish–Lithuanian Commonwealth, eventually leading to the First Partition of Poland. Turkish losses included diplomatic defeats which led to its decline as a threat to Europe, the loss of its exclusive control over the Orthodox millet, and the beginning of European bickering over the Eastern Question that would feature in European diplomacy until the dissolution of the Ottoman Empire in the aftermath of World War I.

The Polish–Soviet War (14 February 1919 – 18 March 1921) was fought primarily between the Second Polish Republic and the Russian Soviet Federative Socialist Republic, following World War I and the Russian Revolution.

After the collapse of the Central Powers and the Armistice of 11 November 1918, Vladimir Lenin's Soviet Russia annulled the Treaty of Brest-Litovsk and moved forces westward to reclaim the Ober Ost regions abandoned by the Germans. Lenin viewed the newly independent Poland as a critical route for spreading communist revolutions into Europe. Meanwhile, Polish leaders, including Józef Piłsudski, aimed to restore Poland's pre-1772 borders and secure the country's position in the region. Throughout 1919, Polish forces occupied much of present-day Lithuania and Belarus, emerging victorious in the Polish–Ukrainian War. However, Soviet forces regained strength after their victories in the Russian Civil War, and Symon Petliura, leader of the Ukrainian People's Republic, was forced to ally with Piłsudski in 1920 to resist the advancing Bolsheviks.

Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was the monarch of Prussia from 1740 until his death in 1786. He was the last Hohenzollern monarch titled King in Prussia, declaring himself King of Prussia after annexing Royal Prussia from the Polish–Lithuanian Commonwealth in 1772. His most significant accomplishments include military successes in the Silesian wars, reorganisation of the Prussian Army, the First Partition of Poland, and patronage of the arts and the Enlightenment. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "Old Fritz" (German: der Alte Fritz).

In his youth, Prince Frederick was more interested in music and philosophy than war, which led to clashes with his authoritarian father, Frederick William I of Prussia. However, upon ascending to the throne, he attacked and annexed the rich Austrian province of Silesia in 1742, winning military acclaim. He became an influential military theorist, whose analyses emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.

The Ruthenian Voivodeship (Latin: Palatinatus russiae; Polish: Województwo ruskie; Ukrainian: Руське воєводство, romanized: Ruske voievodstvo) was a voivodeship of the Crown of the Kingdom of Poland from 1434 until the First Partition of Poland in 1772, with its center in the city of Lwów (lat. Leopolis) (modern day Lviv). Together with a number of other voivodeships of southern and eastern part of the Kingdom of Poland, it formed Lesser Poland Province. Following the Partitions of Poland, most of Ruthenian Voivodeship, except for its northeastern corner, was annexed by the Habsburg monarchy, as part of the province of Galicia. Today, the former Ruthenian Voivodeship is divided between Poland and Ukraine.

The Kingdom of Galicia and Lodomeria, also known as Austrian Galicia or colloquially Austrian Poland, was a constituent possession of the Habsburg monarchy in the historical region of Galicia in Eastern Europe. The crown land was established in 1772. The lands were annexed from the Polish-Lithuanian Commonwealth as part of the First Partition of Poland. In 1804 it became a crown land of the newly proclaimed Austrian Empire. From 1867 it was a crown land within the Cisleithanian or Austrian half of the dual monarchy of Austria-Hungary. It maintained a degree of provincial autonomy. Its status remained unchanged until the dissolution of the monarchy in 1918.

The domain was initially carved in 1772 from the southwestern part of the Polish–Lithuanian Commonwealth. During the following period, several territorial changes occurred. In 1795 the Habsburg monarchy participated in the Third Partition of Poland and annexed additional Polish-held territory, that was renamed as West Galicia. That region was lost in 1809. Some other changes also occurred, by territorial expansion or contraction (1786, 1803, 1809, 1815, 1846, 1849). After 1849, borders of the crown land remained stable until 1918.

Royal Prussia (Polish: Prusy Królewskie; German: Königlich-Preußen or Preußen Königlichen Anteils, Kashubian: Królewsczé Prësë) or Polish Prussia (Polish: Prusy Polskie; German: Polnisch-Preußen) became a province of the Crown of the Kingdom of Poland, which was annexed following the Second Peace of Thorn (1466) from territory in Pomerelia and western Prussia which had been part of the State of the Teutonic Order. Royal Prussia retained its autonomy, governing itself and maintaining its own laws, customs, and rights.

In 1569, Royal Prussia was fully integrated into the Crown of the Kingdom of Poland and its autonomy was largely abolished. As a result, the Royal Prussian parliament was incorporated into the Sejm of the Polish–Lithuanian Commonwealth. In 1772 and 1793, after the first and second partition of Poland, the former territory of Royal Prussia was annexed by the Kingdom of Prussia and subsequently re-organized into the province of West Prussia. This occurred at the time of the First Partition of Poland, with other parts of the Polish–Lithuanian Commonwealth being annexed by the Russian Empire and Habsburg Austria.

The Inflanty Voivodeship (Polish: Województwo inflanckie), or Livonian Voivodeship (Lithuanian: Livonijos vaivadija), also known as Polish Livonia, was an administrative division and local government in the Polish–Lithuanian Commonwealth, since it was formed in the 1620s out of the Wenden Voivodeship and lasted until the First Partition of Poland in 1772. The Inflanty Voivodeship was one of the few territories of the Polish–Lithuanian Commonwealth to be ruled jointly by Poland and Lithuania.
