Odesa in the context of "Grand Duchy of Lithuania"

The Black Sea is a marginal sea lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper and Dniester. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe.

The Black Sea, not including the Sea of Azov, covers 436,400 km (168,500 sq mi), has a maximum depth of 2,212 m (7,257 ft), and a volume of 547,000 km (131,000 cu mi).Most of its coasts ascend rapidly.These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north.In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farther north. The longest east–west extent is about 1,175 km (730 mi). Important cities along the coast include (clockwise from the Bosporus) the northern suburbs of Istanbul, Burgas, Varna, Constanța, Odesa, Yalta, Kerch, Yevpatoria, Sevastopol, Novorossiysk, Sochi, Poti, Batumi, Rize, Trabzon, Ordu, Simferopol, Samsun and Zonguldak.

Ukraine is a country in Eastern Europe. It is the second-largest country in Europe after Russia, which borders it to the east and northeast. Ukraine also borders Belarus to the north; Poland and Slovakia to the west; Hungary, Romania and Moldova to the southwest; and the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city, followed by Kharkiv, Odesa, and Dnipro. Ukraine's official language is Ukrainian.

Humans have inhabited Ukraine since 32,000 BC. During the Middle Ages, it was the site of early Slavic expansion and later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. Kievan Rus' became the largest and most powerful realm in Europe in the 10th and 11th centuries, but gradually disintegrated into rival regional powers before being destroyed by the Mongols in the 13th century. For the next 600 years the area was contested, divided, and ruled by a variety of external powers, including the Grand Duchy of Lithuania, the Kingdom of Poland, the Polish–Lithuanian Commonwealth, the Austrian Empire, the Ottoman Empire, and the Tsardom of Russia.

Odesa Raion (Ukrainian: Одеський район) or Odessa Raion (Russian: Одесский район) is a raion (district) of Odesa Oblast, Ukraine. It was created on 17 July 2020 as part of the reform of administrative divisions of Ukraine. Biliaivka Raion, Biliaivka and Illichivsk municipalities, parts of Lyman and Ovidiopol raions, as well as the cities of Odesa, Teplodar, and Yuzhne were merged into Odesa Raion. The center of the raion is the city of Odesa. Population: 1,378,490 (2022 estimate).

Odesa Oblast (Ukrainian: Одеська область, romanized: Odeska oblast), also referred to as Odeshchyna (Одещина), is an oblast (province) of southwestern Ukraine, located along the northern coast of the Black Sea. Its administrative centre is the city of Odesa. Population: 2,351,382 (2022 estimate).

The length of coastline (sea-coast and estuaries) reaches 300 km (190 mi), while the state border stretches for 1,200 km (750 mi). The region has eight seaports and five of the biggest lakes, including Yalpuh Lake, in Ukraine. With over 80,000 ha (200,000 acres) of vineyards, it is also the largest wine-growing region in Ukraine.

The Historic Centre of Odesa (Ukrainian: Історичний центр Одеси, romanized: Istorychnyi tsentr Odesy), Historical City Centre of Odesa, or Centre of Odesa is a city centre and World Heritage Site in Odesa, Ukraine. It was listed in 2023, and currently, it is on the list of World Heritage Sites in Danger because of the Russo-Ukrainian war.

During the southern Ukraine offensive of the Russian invasion of Ukraine, the city of Odesa and the surrounding region have been the target of shelling and air strikes by Russian forces on multiple occasions since the conflict began, fired in part by Russian warships situated offshore in the Black Sea. The city has also been targeted by Russian cruise missiles.

Khadjibey (Turkish and Crimean Tatar: Hacıbey; Ukrainian: Коцюбіїв) was a fortress and a haven by the Gulf of Odesa, in the location of the modern city of Odesa, Ukraine. The settlement was destroyed and abandoned in the 15th or 16th century and was revived under the Ottoman Empire in the 18th century.

Other known spellings include Khadzhibey, Khadjibei, Hajibey, Khacdjibei, Hacıbey, Hocabey, Gadzhibei, Chadžibėjus, Codjabey, Kachybey, Kotsiubey, Kotsiubiiv.

The Russo-Turkish War of 1787–1792 involved an unsuccessful attempt by the Ottoman Empire to regain lands lost to the Russian Empire in the course of the previous Russo-Turkish War (1768–1774). It took place concomitantly with the Austro-Turkish War (1788–1791), the Russo-Swedish War (1788–1790), and the Theatre War.

During the Russian-Turkish War of 1787–1792, on 25 September 1789, a detachment of the Imperial Russian Army under Alexander Suvorov and Ivan Gudovich, took Khadjibey and Yeni Dünya for the Russian Empire. In 1794, Odesa replaced Khadjibey by a decree of the Russian Empress Catherine the Great.

An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel–electric or gas turbine–electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system.

Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack of reciprocating parts means electric locomotives are easier on the track, reducing track maintenance. Power plant capacity is far greater than any individual locomotive uses, so electric locomotives can have a higher power output than diesel locomotives and they can produce even higher short-term surge power for fast acceleration. Electric locomotives are ideal for commuter rail service with frequent stops. Electric locomotives are used on freight routes with consistently high traffic volumes, or in areas with advanced rail networks. Power plants, even if they burn fossil fuels, are far cleaner than mobile sources such as locomotive engines. The power can also come from low-carbon or renewable sources, including geothermal power, hydroelectric power, biomass, solar power, nuclear power and wind turbines. Electric locomotives usually cost 20% less than diesel locomotives, their maintenance costs are 25–35% lower, and cost up to 50% less to run.
