Red Ruthenia in the context of "Kingdom of Galicia–Volhynia"

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.

Ruthenia is an exonym, originally used in Medieval Latin, as one of several terms for Rus'. Originally, the term Rus' land referred to a triangular area, which mainly corresponds to the tribe of Polans in Dnieper Ukraine. Ruthenia was used to refer to the East Slavic and Eastern Orthodox people of the Grand Duchy of Lithuania and the Kingdom of Poland, and later the Polish-Lithuanian Commonwealth and Austria-Hungary, mainly to Ukrainians and sometimes Belarusians, corresponding to the territories of modern Belarus, Ukraine, Eastern Poland and some of western Russia.

Historically, in a broader sense, the term was used to refer to all the territories under Kievan dominion (mostly East Slavs).

Lublin Voivodeship (Polish: województwo lubelskie [vɔjɛˈvut͡stfɔ luˈbɛlskʲɛ] ) is a voivodeship (province) of Poland, located in the southeastern part of the country, with its capital being the city of Lublin.

The region is named after its largest city and regional capital, Lublin, and its territory is made of four historical lands: the western and central part of the voivodeship, with Lublin itself, belongs to Lesser Poland, the eastern part of Lublin Area belongs to Cherven Cities/Red Ruthenia, and the northeast belongs to Polesie and Podlasie.Lublin Voivodeship borders Subcarpathian Voivodeship to the south, Świętokrzyskie Voivodeship to the south-west, Masovian Voivodeship to the west and north, Podlaskie Voivodeship along a short boundary to the north, Belarus (Brest Region) and Ukraine (Lviv and Volyn Regions) to the east. The region's population as of 2024 was 1,996,440. It covers an area of 25,155 square kilometres (9,712 sq mi).

Western Ukraine or West Ukraine (Ukrainian: Західна Україна, romanized: Zakhidna Ukraina, IPA: [ˈzɑxidnɐ ʊkrɐˈjinɐ]) refers to the western territories of Ukraine. There is no universally accepted definition of the territory's boundaries, but the contemporary Ukrainian administrative regions (oblasts) of Chernivtsi, Ivano-Frankivsk, Lviv, Ternopil and Zakarpattia (which were part of the former Austro-Hungarian Empire) are typically included. In addition, Volyn and Rivne oblasts (parts of the territory annexed from the Polish–Lithuanian Commonwealth during its Third Partition) are also usually included. In modern sources, Khmelnytskyi Oblast is often included because of its geographical, linguistic and cultural association with Western Ukraine, although this cannot be confirmed from a historical and political point of view. It includes several historical regions such as Carpathian Ruthenia, Halychyna including Pokuttia (the eastern portion of Eastern Galicia), most of Volhynia, northern Bukovina and the Hertsa region, and Podolia. Western Ukraine is sometimes considered to include areas of eastern Volhynia, Podolia, and the small northern portion of Bessarabia.

The area of Western Ukraine was ruled by various polities, including the Kingdom of Galicia–Volhynia, which became part of the Polish–Lithuanian Commonwealth, but also the Principality of Moldavia; it would then variously come under rule of the Austrian Empire, Austria-Hungary, the Second Polish Republic, the Kingdom of Romania, and finally the Soviet Union (via the Ukrainian Soviet Socialist Republic) in 1939 and 1940 following the invasion of Poland and the Soviet occupation of Bessarabia and Northern Bukovina, with the borders finalized after the end of World War II. After the dissolution of the Soviet Union, it became part of the independent Ukrainian state.

Galicia (/ɡəˈlɪʃ(i)ə/ gə-LISH-(ee-)ə; also known by the variant name Galizia; Polish: Galicja, IPA: [ɡaˈlit͡sja] ; Ukrainian: Галичина, romanized: Halychyna, IPA: [ɦɐlɪtʃɪˈnɑ]; Yiddish: גאַליציע, romanized: Galitsye; see below) is a historical and geographic region spanning what is now southeastern Poland and western Ukraine, long part of the Polish–Lithuanian Commonwealth. It covers much of the other historic regions of Red Ruthenia (centered on Lviv) and Lesser Poland (centered on Kraków).

The name of the region derives from the medieval city of Halych, and was first mentioned in Hungarian historical chronicles in the year 1206 as Galiciæ. The eastern part of the region was controlled by the medieval Kingdom of Galicia–Volhynia before it was annexed by the Kingdom of Poland in 1352 and became part of the Ruthenian Voivodeship. During the partitions of Poland, it was incorporated into a crown land of the Austrian Empire — the Kingdom of Galicia and Lodomeria.

Podkarpackie Voivodeship (Polish pronunciation: [pɔt.karˈpat͡s.kjɛ]; lit. 'Subcarpathian') is a voivodeship, or province, in the southeastern corner of Poland. Its administrative capital and largest city is Rzeszów. It is governed by the Subcarpathian Regional Assembly and the voivodeship marshal.

The name derives from the region's location near the Carpathian Mountains, and the voivodeship comprises areas of two historic regions of Central Europe—Lesser Poland (western and northwestern counties) and Cherven Cities/Red Ruthenia.

Mieszko II Lambert (Polish pronunciation: [ˈmjɛʂkɔ ˈdruɡʲi ˈlambɛrt] ; c. 990 – 10/11 May 1034) was King of Poland from 1025 to 1031 and Duke from 1032 until his death.

He was the second son of Bolesław I the Brave but the eldest born from his third wife, Emnilda of Lusatia. He organized two devastating invasions of Saxony in 1028 and 1030. Then, he ran a defensive war against Germany, Bohemia and the Kievan princes. Mieszko II was forced to escape from the country in 1031 after an attack by Yaroslav I the Wise, who installed Mieszko's older half-brother Bezprym on the Polish throne. Mieszko II took refuge in Bohemia, where he was imprisoned by Duke Oldrich. In 1032 he regained power in one of Poland's three districts, then united the country, making good use of the remaining power structures. At this time, several Polish territorial acquisitions of his father were lost: Upper Lusatia (also known as Milsko), part of Lower Lusatia, Red Ruthenia, the western and central parts of Upper Hungary (now Slovakia) and probably Moravia.

White Ruthenia (Belarusian: Белая Русь, romanized: Biełaja Ruś; Polish: Ruś Biała; Russian: Белая Русь, romanized: Belaya Rus'; Ukrainian: Біла Русь, romanized: Bila Ruś; Yiddish: רייסן, romanized: Raysn) is one of the historical divisions of Kievan Rus' according to the color scheme, which also includes Black and Red Ruthenia. In the Late Middle Ages and Early Modern period, the name White Ruthenia was characterized by instability, designating a number of different regions on the territory of modern Belarus, Russia, and Ukraine. It is recorded mainly in Western European sources, starting from the middle of the 13th century.
