Vinnytsia in the context of "Vinnytsia massacre"

Vinnytsia Oblast (Ukrainian: Вінницька область, romanized: Vinnytska oblast, IPA: [ˈwinːɪtsʲkɐ ˈɔblɐsʲtʲ]), also referred to as Vinnychchyna (Ukrainian: Вінниччина), is an oblast in central Ukraine. Its administrative center is Vinnytsia. The oblast has a population of 1,509,515 (2022 estimate).

The Soviet invasion of Ukraine was a major offensive by the Ukrainian Front of the Red Army against the Ukrainian People's Republic (UPR) during the Soviet–Ukrainian War. The invasion was first planned in November 1918, after the Council of People's Commissars of the Russian Soviet Federative Socialist Republic annulled the Treaty of Brest-Litovsk, and was launched in the first days of January 1919, with the occupation of Kharkiv. Its aim was to join Ukraine to the RSFSR, as the country was of significant economic, demographic and strategic importance for the Bolsheviks. In the longer term, the capture of the Black Sea coast was to prevent an intervention by the Allies in support of the Volunteer Army. Finally, the Bolsheviks intended to extend the area they control as far as possible to the west, in order to be able to support the other revolutionary movements in Europe.

In the first days of January 1919, by joining forces with local workers' units, the troops of the 1st Ukrainian Soviet Division [uk] took Kharkiv, which was announced as the seat of the Provisional Workers' and Peasants' Government of Ukraine. Then they quickly captured most of northern and eastern Ukraine, and on 5 February 1919, they occupied Kyiv. The Directorate of Ukraine moved to Vinnytsia, then to Kamianets-Podilskyi. By spring, the Red Army had reached the Zbruch and repelled a counteroffensive by the Ukrainian People's Army (UPA) that threatened Kyiv.

Podolia Governorate was an administrative-territorial unit (guberniya) of the Southwestern Krai of the Russian Empire. It bordered Volhynian Governorate to the north, Kiev Governorate to the east, Kherson Governorate to the southeast, Bessarabia Governorate to the south, and Austria to the west. Its administrative centre was Kamenets-Podolsky (Kamianets-Podilskyi), which later moved to Vinnitsa (Vinnytsia). The governorate covered areas of Ukraine's partially Khmelnytskyi and most of Vinnytsia Oblasts, along with the fractionally recognised state of Transnistria.

Vinnytsia railway station (Ukrainian: Станція Вінниця) is the main railway station in the Ukrainian city of Vinnytsia. It first opened in 1870, and is a part of Southwestern Railways.

According to the "Investment Atlas of Ukraine", the station receives around 1.3 million passengers every year.

Ukraine, formerly a republic of the Union of Soviet Socialist Republics (USSR) from 1922 to 1991, once hosted Soviet nuclear weapons and delivery systems on its territory. The former Soviet Union had its nuclear program expanded to only four of its republics: Belarus, Kazakhstan, Russia, and Ukraine. After its dissolution in 1991, Ukraine inherited about 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 nuclear warheads that remained on Ukrainian territory. Thus Ukraine became the third largest nuclear power in the world (possessing 300 more nuclear warheads than Kazakhstan, 6.5 times less than the United States, and ten times less than Russia) and held about one third of the former Soviet nuclear weapons, delivery system, and significant knowledge of its design and production. While all these weapons were located on Ukrainian territory, they were not under Ukraine's control.

In 1994, Ukraine agreed to transfer these weapons to Russia for dismantlement and became a party to the Treaty on the Non-Proliferation of Nuclear Weapons, in exchange for economic compensation and assurances from Russia, the United States and the United Kingdom to respect Ukrainian independence and sovereignty within its existing borders. Almost twenty years later, Russia, one of the parties to the agreement, invaded Ukraine in 2014.
