Ternopil Oblast in the context of "Seret (river)"

Galician Jews or Galitzianers (Yiddish: גאַליציאַנער, romanized: Galitsianer) are members of the subgroup of Ashkenazi Jews originating and developed in the Kingdom of Galicia and Lodomeria and Bukovina from contemporary western Ukraine (Lviv, Ivano-Frankivsk, and Ternopil Oblasts) and from south-eastern Poland (Subcarpathian and Lesser Poland). Galicia proper, which was inhabited by Ruthenians, Poles and Jews, became a royal province within Austria-Hungary after the Partitions of Poland in the late 18th century. Galician Jews primarily spoke Yiddish.

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.

Volhynia or Volynia (/voʊˈlɪniə/ voh-LIN-ee-ə; see #Names and etymology) is a historic region in Central and Eastern Europe, between southeastern Poland, southwestern Belarus, and northwestern Ukraine. The borders of the region are not clearly defined, but in Ukraine it is roughly equivalent to Volyn Oblast, Rivne Oblast, and the northern part of the Khmelnytskyi Oblast and Ternopil Oblast. The territory that still carries the name is Volyn Oblast.

Volhynia has changed hands numerous times throughout history and been divided among competing powers. For centuries it was part of the Polish-Lithuanian Commonwealth. After the Russian annexation during the Partitions of Poland, all of Volhynia was made part of the Pale of Settlement on the southwestern border of the Russian Empire. Important cities include Rivne, Lutsk, Zviahel, and Volodymyr.

Eastern Galicia (Ukrainian: Східна Галичина, romanized: Skhidna Halychyna; Polish: Galicja Wschodnia; German: Ostgalizien) is a geographical region in Western Ukraine (present day oblasts of Lviv, Ivano-Frankivsk and Ternopil), having also essential historic importance in Poland.

Galicia was formed within the Austrian Empire during the years 1772–1918. Eastern Galicia now includes all of the Lviv and Ivano-Frankivsk Oblasts (regions) of Ukraine as well as Ternopil Oblast, with its northern strip bordering the former Kremenets, Shumsk and Lanivtsi Raions and the northern part of Zbarazh Raion. On the other hand, the western part of Eastern Galicia is located in Poland (the eastern part of the Subcarpathian Voivodeship, including Przemyśl, Sanok, Jarosław, Lubaczów, Lesko and Bieszczady, as well as the areas around these cities and places). A tiny piece of Eastern Galicia, the town of Lubycza Królewska and its surrounding area, is also located in the Lublin Voivodeship. However, Tomaszów Lubelski, 15 km away, is no longer part of Galicia, nor did it belong to the Austrian state during the partitions of Poland: it was made a part of Congress Poland, and therefore of the Russian Empire, following the abolition of the Duchy of Warsaw. The area of Eastern Galicia is about 46,800 km (18,100 sq miles).

Pidkamin (Ukrainian: Підкамінь, lit. 'Below the Rock'; Polish: Podkamień) is a rural settlement in Zolochiv Raion, Lviv Oblast, western Ukraine, near the administrative border of three oblasts, Lviv, Rivne, and Ternopil. Pidkamin hosts the administration of Pidkamin settlement hromada, one of the hromadas (municipalities) of Ukraine. Population: 1,895 (2022 estimate).

Ternopil, known until 1944 mostly as Tarnopol, is a city in western Ukraine, located on the banks of the Seret River. Ternopil is one of the major cities of Western Ukraine and the historical regions of Galicia and Podolia. The population of Ternopil was estimated at 225,004 (2022 estimate).

The city is the administrative center of Ternopil Oblast (region), as well as of surrounding Ternopil Raion (district) within the oblast. It hosts the administration of Ternopil urban hromada, one of the hromadas of Ukraine.

The Optymistychna (Ukrainian: Оптимістична, lit. 'optimistic', also known as Peshchera Optimistitscheskaya) is a gypsum cave located near the Ukrainian village of Korolivka, Chortkiv Raion, Ternopil Oblast. Approximately 264 km (164 mi) of passageways have been mapped within. As a result, it is the longest cave in Europe and the seventh-longest cave in the world, after Mammoth Cave, Sistema Sac Actun, Jewel Cave, Shuanghedong and Sistema Ox Bel Ha. It is also the longest gypsum cave in the world.
