A field army is a military formation in many armed forces, composed of two or more corps and may be subordinate to an army group. Air armies are equivalent formation within some air forces. A field army is composed of 100,000 to 150,000 troops. Particular field armies are named or numbered to distinguish them from "army" in the sense of an entire national land military force. In English, the typical style for naming field armies is word numbers, such as "First Army". A field army may be given a geographical name in addition to or as an alternative to a numerical name, such as the British Army of the Rhine, Army of the Niemen or Aegean Army; the Roman army was among the first to feature a formal field army, in the sense of a large, combined arms formation, namely the sacer comitatus, which may be translated as "sacred escort". The term is derived from the fact that they were commanded by Roman emperors, when they acted as field commanders. While the Roman comitatensis is sometimes translated as "field army", it may be translated as the more generic "field force" or "mobile force".
In some armed forces, an "army" has been equivalent to a corps-level unit. Prior to 1945, this was the case with a gun within the Imperial Japanese Army, for which the formation equivalent in size to a field army was an "area army". In the Soviet Red Army and the Soviet Air Forces, an army was subordinate in wartime to a front, it contained at least three to five divisions along with artillery, air defense and other supporting units. It could be classified as either tank army. In peacetime, a Soviet army was subordinate to a military district. Modern field armies are large formations which vary between armed forces in size and scope of responsibility. For instance, within NATO a field army is composed of a headquarters, controls at least two corps, beneath which are a variable number of divisions. A battle is influenced at the field army level by transferring divisions and reinforcements from one corps to another to increase the pressure on the enemy at a critical point. NATO armies are commanded by a general or lieutenant general.

Ukraine, sometimes called the Ukraine, is a country in Eastern Europe. Excluding Crimea, Ukraine has a population of about 42.5 million, making it the 32nd most populous country in the world. Its capital and largest city is Kiev. Ukrainian is the official language and its alphabet is Cyrillic; the dominant religions in the country are Greek Catholicism. Ukraine is in a territorial dispute with Russia over the Crimean Peninsula, which Russia annexed in 2014. Including Crimea, Ukraine has an area of 603,628 km2, making it the largest country within Europe and the 46th largest country in the world; the territory of modern Ukraine has been inhabited since 32,000 BC. During the Middle Ages, the area was a key centre of East Slavic culture, with the powerful state of Kievan Rus' forming the basis of Ukrainian identity. Following its fragmentation in the 13th century, the territory was contested and divided by a variety of powers, including Lithuania, Austria-Hungary, the Ottoman Empire and Russia. A Cossack republic emerged and prospered during the 17th and 18th centuries, but its territory was split between Poland and the Russian Empire, merged into the Russian-dominated Soviet Union in the late 1940s as the Ukrainian Soviet Socialist Republic.
In 1991 Ukraine gained its independence from the Soviet Union in the aftermath of its dissolution at the end of the Cold War. Before its independence, Ukraine was referred to in English as "The Ukraine", but most sources have since moved to drop "the" from the name of Ukraine in all uses. Following its independence, Ukraine declared itself a neutral state. In 2013, after the government of President Viktor Yanukovych had decided to suspend the Ukraine-European Union Association Agreement and seek closer economic ties with Russia, a several-months-long wave of demonstrations and protests known as the Euromaidan began, which escalated into the 2014 Ukrainian revolution that led to the overthrow of Yanukovych and the establishment of a new government; these events formed the background for the annexation of Crimea by Russia in March 2014, the War in Donbass in April 2014. On 1 January 2016, Ukraine applied the economic component of the Deep and Comprehensive Free Trade Area with the European Union.
Ukraine is ranks 88th on the Human Development Index. As of 2018, Ukraine has the second lowest GDP per capita in Europe. At US$40, it has the lowest median wealth per adult in the world, it suffers from a high poverty rate and severe corruption. However, because of its extensive fertile farmlands, Ukraine is one of the world's largest grain exporters. Ukraine maintains the second-largest military in Europe after that of Russia; the country is home to a multi-ethnic population, 77.8 percent of whom are Ukrainians, followed by a large Russian minority, as well as Georgians, Belarusians, Crimean Tatars, Jews and Hungarians. Ukraine is a unitary republic under a semi-presidential system with separate powers: legislative and judicial branches; the country is a member of the United Nations, the Council of Europe, the OSCE, the GUAM organization, one of the founding states of the Commonwealth of Independent States. There are different hypotheses as to the etymology of the name Ukraine. According to the older widespread hypothesis, it means "borderland", while some more recent linguistic studies claim a different meaning: "homeland" or "region, country"."The Ukraine" used to be the usual form in English, but since the Declaration of Independence of Ukraine, "the Ukraine" has become less common in the English-speaking world, style-guides recommend not using the definite article.
"The Ukraine" now implies disregard for the country's sovereignty, according to U. S. ambassador William Taylor. The Ukrainian position is that the usage of "'The Ukraine' is incorrect both grammatically and politically." Neanderthal settlement in Ukraine is seen in the Molodova archaeological sites which include a mammoth bone dwelling. The territory is considered to be the location for the human domestication of the horse. Modern human settlement in Ukraine and its vicinity dates back to 32,000 BC, with evidence of the Gravettian culture in the Crimean Mountains. By 4,500 BC, the Neolithic Cucuteni–Trypillia culture flourished in wide areas of modern Ukraine including Trypillia and the entire Dnieper-Dniester region. During the Iron Age, the land was inhabited by Cimmerians and Sarmatians. Between 700 BC and 200 BC it was Scythia. Beginning in the sixth century BC, colonies of Ancient Greece, Ancient Rome and the Byzantine Empire, such as Tyras and Chersonesus, were founded on the northeastern shore of the Black Sea.
These colonies thrived well into the 6th century AD. The Goths stayed in the area but came under the sway of the Huns from the 370s AD. In the 7th century AD, the territory of eastern Ukraine was the centre of Old Great Bulgaria. At the end of the century, the majority of Bulgar tribes migrated in different directions, the Khazars took over much of the land. In the 5th and 6th centuries, the Antes were located in the territory of; the Antes were the ancestors of Ukrainians: White Croats, Polans, Dulebes and Tiverians. Migrations from Ukraine throughout the Balkans established many Southern Slavic nations. Northern migrations, reaching to the Ilmen l
The Don is one of the major Eurasian rivers of Russia and the fifth-longest river in Europe. The Don basin is between the Dnieper basin to the west, the Volga basin to the east, the Oka basin to the north; the Don rises in the town of Novomoskovsk 60 kilometres southeast of Tula, flows for a distance of about 1,870 kilometres to the Sea of Azov. From its source, the river first flows southeast to Voronezh southwest to its mouth; the main city on the river is Rostov on Don. Its main tributary is the Seversky Donets. According to the Kurgan hypothesis, the Volga-Don river region was the homeland of the Proto-Indo-Europeans c. 4000BC. The Don river functioned as a fertile cradle of civilization where the Neolithic farmer culture of the Near East fused with the hunter-gatherer culture of Siberian groups, resulting in the nomadic pastoralism of the Proto-Indo-Europeans. In antiquity, the river was viewed as the border between Europe and Asia by some ancient Greek geographers. In the Book of Jubilees, it is mentioned as being part of the border, beginning with its easternmost point up to its mouth, between the allotments of sons of Noah, that of Japheth to the north and that of Shem to the south.
During the times of the old Scythians it was known in Greek as the Tanaïs and has been a major trading route since. Tanais appears in ancient Greek sources as both the name of the river and of a city on it, situated in the Maeotian marshes. Pliny gives the Scythian name of the Tanais as Silys. According to Plutarch, the Don River was home to the legendary Amazons of Greek mythology; the area around the estuary is speculated to be the source of the Black Death. While the lower Don was well known to ancient geographers, its middle and upper reaches were not mapped with any accuracy before the gradual conquest of the area by Muscovy in the 16th century; the Don Cossacks, who settled the fertile valley of the river in the 16th and 17th centuries, were named after the river. The fort of Donkov was founded by the princes of Ryazan in the late 14th century; the fort stood on the left bank of the Don, about 34 kilometers from the modern town of Dankov, until 1568, when it was destroyed by the Crimean Tatars, but soon restored at a better fortified location.
It is shown as Donko in Mercator's Atlas, Donkov was again relocated in 1618, appearing as Donkagorod in Joan Blaeu's map of 1645. Both Blaeu and Mercator follow the 16th-century cartographic tradition of letting the Don originate in a great lake, labelled Resanskoy ozera by Blaeu. Mercator still follows Giacomo Gastaldo in showing a waterway connecting this lake to Ryazan and the Oka River. Mercator shows Mtsensk as a great city on this waterway, suggesting a system of canals connecting the Don with the Zusha and Upa centered on a settlement Odoium, reported as Odoium lacum in the map made by Baron Augustin von Mayerberg, leader of an embassy to Muscovy in 1661. In modern literature, the Don region was featured in the work And Quiet Flows the Don by Mikhail Aleksandrovich Sholokhov, a Nobel-prize winning writer from the stanitsa of Veshenskaya. At its easternmost point, the Don comes near the Volga, the Volga-Don Canal, connecting the two rivers, is a major waterway; the water level of the Don in this area is raised by the Tsimlyansk Dam, forming the Tsimlyansk Reservoir.
For the next 130 kilometres below the Tsimlyansk Dam, the sufficient water depth in the Don River is maintained by the sequence of three dam-and-ship-lock complexes: the Nikolayevsky Ship Lock, Konstantinovsk Ship Lock, the best known of the three, the Kochetovsky Ship Lock. The Kochetovsky Lock, built in 1914–1919 and doubled in 2004–2008, is 7.5 kilometres below the fall of the Seversky Donets into the Don, 131 kilometres upstream of Rostov-on-Don, the Kochetovsky Ship Lock is located. This facility, with its dam, maintains sufficient water level both in its section of the Don and in the lowermost stretch of the Seversky Donets; this is presently the last lock on the Don. In order to improve shipping conditions in the lower reaches of the Don, the waterway authorities support the proposals for the construction of one or two more low dams with locks, in Bagayevsky District and also in Aksaysky District.

Operation Little Saturn
Operation Saturn, revised as Operation Little Saturn, was a Red Army operation on the Eastern Front of World War II that led to battles in the North Caucasus and Donets Basin regions of the Soviet Union from December 1942 to February 1943. The success of Operation Uranus, launched on 19 November 1942, had trapped 250,000–300,000 troops of General Friedrich Paulus' German 6th Army and 4th Panzer Army in Stalingrad. To exploit this victory, the Soviet general staff planned a winter campaign of continuous and ambitious offensive operations, codenamed "Saturn". Joseph Stalin reduced his ambitious plans to a small campaign codenamed "Operation Little Saturn"; the offensive succeeded in smashing Germany's Italian and Hungarian allies, applied pressure on the over stretched German forces in Eastern Ukraine and prevented further German advances to the relief of the entrapped forces at Stalingrad. Despite these victories, the Soviets themselves became over extended, setting up the stages for the German offensives of the Third Battle of Kharkov and the Battle of Kursk.
On 17 May 1942, German Army Groups A and B launched a counteroffensive against advancing Soviet armies around the city of Kharkov, resulting in the Second Battle of Kharkov. By 6 July, General Hermann Hoth's Fourth Panzer Army had taken the city of Voronezh, threatening to collapse the Red Army's resistance. By early August, General Paul Ludwig Ewald von Kleist's First Panzer Army had reached the oil center of Maykop, 500 kilometres south of the city of Rostov, taken by the Fourth Panzer Army on 23 July; the rapid German advance threatened to cut the Soviet Union off from its southern territories, while threatening to cut the lend-lease supply lines from Persia. However, the offensive began to peter out, as the offensive's supply train struggled to keep up with the advance and spearhead units began to run low on fuel and manpower. Operation Uranus was the codename of the Soviet strategic operation in World War II which led to the encirclement of the German Sixth Army and Fourth Romanian armies, portions of the German Fourth Panzer Army.
The operation formed part of the ongoing Battle of Stalingrad, was aimed at destroying German forces in and around Stalingrad. Planning for Operation Uranus had commenced as early as September 1942, was developed with plans to envelop and destroy German Army Group Center and German forces in the Caucasus; the Red Army took advantage of the fact that German forces in the southern Soviet Union were overstretched around Stalingrad, using weaker Romanian armies to guard their flanks. These Axis armies were deployed in open positions on the steppe and lacked heavy equipment to deal with Soviet armor. Operation Winter Storm, undertaken between 12–23 December 1942, was the German Fourth Panzer Army's attempt to relieve encircled Axis forces during the Battle of Stalingrad. In late November, the Red Army completed Operation Uranus, which resulted in the encirclement of Axis personnel in and around the city of Stalingrad. German forces within the Stalingrad Pocket and directly outside were reorganized under Army Group Don, under the command of Field Marshal Erich von Manstein.
As the Red Army continued to build strength, in an effort to allocate as many resources as possible to the eventual launch of the planned Operation Saturn, which aimed to isolate Army Group A from the rest of the German Army, the Luftwaffe had begun an attempt to supply German forces in Stalingrad through an air bridge. However, as the Luftwaffe proved incapable of carrying out its mission and it became more obvious that a successful breakout could only occur if it was launched as early as possible, Manstein decided to plan and launch a dedicated relief effort. After the defeat of the Romanian Army around Stalingrad and the successful encirclement of the German Sixth Army, Stalin started a counter-offensive nicknamed "Operation Little Saturn" in order to enlarge the area controlled by the Soviet Army in eastern Ukraine until Kharkov and Rostov. Zhukov states the South-Western Front was assigned a mission in which the 1st and 3rd Guard armies and the 5th Tank Army "were to strike out in the general direction of Morozovsk and destroy the enemy grouping in that sector."
They would be supported by the 6th Army of the Voronezh Front. The first stage — an attempt to cut off the German Army Group A in the Caucasus — had to be revised when General Erich von Manstein launched Operation Winter Storm on 12 December in an attempt to relieve the trapped armies at Stalingrad. While General Rodion Malinovsky's Soviet 2nd Guards Army blocked the German advance on Stalingrad, the modified plan Operation Little Saturn was launched on 16 December; this operation consisted of a pincer movement. General Fyodor Isidorovich Kuznetsov's 1st Guards Army and General Dmitri Danilovich Lelyushenko's 3rd Guards Army attacked from the north, encircling 130,000 soldiers of the Italian 8th Army on the Don and advancing to Millerovo; the Italians resisted the Soviet attack for nearly two weeks, although outnumbered 9 to 1 in some sectors, but with huge losses. Manstein sent the 6th Panzer Division to the Italians' aid: of the 130,000 encircled troops, only 45,000 survived after bloody fighting to join the Panzers at Chertkovo on 17 January.
To the south the advance of General Gerasimenko's 28th Army threatened to encircle the 1st Panzer Army and General Trufanov's 51st Army attacked the relief column directly. In a dar
Volgograd Tsaritsyn, 1589–1925, Stalingrad, 1925–1961, is an industrial city and the administrative centre of Volgograd Oblast, Russia. The city lies on the western bank of the Volga River; the Battle of Stalingrad in World War II was one of the largest and bloodiest battles in the history of warfare. Known locally as the "Hero City", it is home to The Motherland Calls, an 85 meter statue dedicated to the heroes of the battle; the city has many tourist attractions, such as museums, sandy beaches, a self-propelled floating church. Its population was 1,021,215 at the 2010 Census, growing from 1,011,417 in the 2002 Census. Although the city may have originated in 1555, documented evidence of Tsaritsyn at the confluence of the Tsaritsa and Volga rivers dates only from 1589. Grigori Zasekin established the fortress Sary Su as part of the defences of the unstable southern border of the Tsardom of Russia; the structure stood above the mouth of the Tsaritsa River on the right bank. It soon became the nucleus of a trading settlement.
In 1607 the fortress garrison rebelled against the troops of Tsar Vasili Shuisky for six months. In 1608 the city acquired St. John the Baptist. At the beginning of the 17th century, the garrison consisted of 350 to 400 people. In 1670 troops of Stepan Razin captured the fortress. In 1708 the insurgent Cossack Kondraty Bulavin held the fortress. In 1717 in the Kuban pogrom, raiders from the Kuban under the command of the Crimean Tatar Bakhti Gerai blockaded the town and enslaved thousands in the area. In August 1774 Yemelyan Pugachev unsuccessfully attempted to storm the city. In 1691 Moscow established a customs-post at Tsaritsyn. In 1708 Tsaritsyn was assigned to the Kazan Governorate. According to the census in 1720, the city had a population of 408 people. In 1773 the city became a district town. From 1779 it belonged to the Saratov Viceroyalty. In 1780 the city came under the newly-established Saratov Governorate. In the 19th century Tsaritsyn became commercial center; the population expanded increasing from fewer than 3,000 people in 1807 to about 84,000 in 1900.
The first railway reached the town in 1862. The first theatre opened in 1872, the first cinema in 1907. In 1913 Tsaritsyn got its first tram-line, the city's first electric lights were installed in the city center. During the Russian Civil War of 1917–1923, Tsaritsyn came under Soviet control from November 1917. In 1918 White troops under the Ataman of the Don Cossack Host, Pyotr Krasnov, besieged Tsaritsyn; the Reds repulsed three assaults by the Whites. However, in June 1919 the White Armed Forces of South Russia under the command of General Denikin captured Tsaritsyn, which they held until January 1920; the fighting from July 1918 to January 1920 became known as the Battle for Tsaritsyn. The city was renamed Stalingrad after Joseph Stalin on April 10, 1925; this was to recognize the city and Stalin's role in its defense against the Whites between 1918 and 1920. In 1931, the German settlement-colony Old Sarepta became a district of Stalingrad. Renamed Krasnoarmeysky Rayon, it became the largest area of the city.
The first institute was opened in 1930. A year the Stalingrad Industrial Pedagogical Institute, now Volgograd State Pedagogical University, was opened. Under Stalin, the city became a center of heavy industry and transshipment by river. During World War II, German and Axis forces attacked the city, in 1942 it became the site of one of the pivotal battles of the war; the Battle of Stalingrad had the greatest casualty figures of any single battle in the history of warfare. The battle became a titanic struggle between Hitler and Stalin as both saw it of great propaganda value, each keenly aware of the namesake of the city, each poured hundreds of thousands of men into the battle; the battle began on August 23, 1942, on the same day, the city suffered heavy aerial bombardment that reduced most of it to rubble. By September, the fighting reached the city center; the fighting was of unprecedented intensity. By early November, the German forces controlled 90 percent of the city and had cornered the Soviets in two narrow pockets, but they were unable to eliminate the last pockets of Soviet resistance before Soviet forces launched a huge counterattack on November 19.
This led to the encirclement of the German Sixth Army and other Axis units. On January 31, 1943 the Sixth Army's commander, Field Marshal Friedrich Paulus, by February 2, with the elimination of straggling German troops, the Battle of Stalingrad was over. In 1945 the Soviet Union awarded Stalingrad the title Hero City for its resistance. Great Britain's King George VI awarded the citizens of Stalingrad the jeweled "Sword of Stalingrad" in recognition of their bravery. A number of cities around the world established sister and twinning links in the spirit of solidarity or reconciliation. One of the first "sister city" projects was that established during World War II between Stalingrad and Coventry in the United Kingdom – both suffered extensive devastation from aerial bombardment. On 10 November 1961, Nikita Khrushchev's administration changed the name of the city to Volg
Operation Uranus was the codename of the Soviet 19–23 November 1942 strategic operation in World War II which led to the encirclement of the German Sixth Army, the Third and Fourth Romanian armies, portions of the German Fourth Panzer Army. The operation was executed at the midpoint of the five month long Battle of Stalingrad, was aimed at destroying German forces in and around Stalingrad. Planning for Operation Uranus had commenced in September 1942, was developed with plans to envelop and destroy German Army Group Center and German forces in the Caucasus; the Red Army took advantage of the German army's poor preparation for winter, the fact that its forces in the southern Soviet Union were overstretched near Stalingrad, using weaker Romanian troops to guard their flanks. These Axis armies lacked heavy equipment to deal with Soviet armor. Due to the length of the front created by the German summer offensive, aimed at taking the Caucasus oil fields and the city of Stalingrad and other Axis forces were forced to guard sectors beyond the length they were meant to occupy.
The situation was exacerbated by the German decision to relocate several mechanized divisions from the Soviet Union to Western Europe. Furthermore, units in the area were depleted after months of fighting those which took part in the fighting in Stalingrad; the Germans could only count on the XXXXVIII Panzer Corps, which had the strength of a single panzer division, the 29th Panzergrenadier Division as reserves to bolster their Romanian allies on the German Sixth Army's flanks. In comparison, the Red Army deployed over one million personnel for the purpose of beginning the offensive in and around Stalingrad. Soviet troop movements were not without problems, due to the difficulties of concealing their build-up, to Soviet units arriving late due to logistical issues. Operation Uranus was first postponed from 8 to 17 November to 19 November. At 07:20 Moscow time on 19 November, Soviet forces on the northern flank of the Axis forces at Stalingrad began their offensive. Although Romanian units were able to repel the first attacks, by the end of 20 November the Third and Fourth Romanian armies were in headlong retreat, as the Red Army bypassed several German infantry divisions.
German mobile reserves were not strong enough to parry the Soviet mechanized spearheads, while the Sixth Army did not react enough nor decisively enough to disengage German armored forces in Stalingrad and reorient them to defeat the impending threat. By late 22 November Soviet forces linked up at the town of Kalach, encircling some 290,000 men east of the Don River. Instead of attempting to break out of the encirclement, German leader Adolf Hitler decided to keep Axis forces in Stalingrad and resupply them by air. In the meantime and German commanders began to plan their next movements. On 28 June 1942, the Wehrmacht began its offensive against Soviet forces opposite of Army Group South, codenamed Case Blue. After breaking through Red Army forces by 13 July, German forces encircled and captured the city of Rostov. Following the fall of Rostov, Hitler split German forces operating in the southern extremity of the southern Russian SFSR in an effort to capture the city of Stalingrad and the Caucasus oil fields.
The responsibility to take Stalingrad was given to the Sixth Army, which turned towards the Volga River and began its advance with heavy air support from the Luftwaffe's Luftflotte 4. On 7 August, two German panzer corps were able to flank and encircle a Soviet force of 50,000 personnel and 1,000 tanks, on 22 August German forces began to cross the Don River to complete the advance towards the Volga; the following day, the Battle of Stalingrad began when vanguards of the Sixth Army penetrated the suburbs of the city. By November the Sixth Army had occupied most of Stalingrad, pushing the defending Red Army to the banks of the Volga River. By this stage, there were indications of an impending Soviet offensive which would target Wehrmacht forces around the city, including increased Soviet activity opposite the Sixth Army's flanks, information gained through the interrogation of Soviet prisoners. However, the German command was intent upon finalizing its capture of Stalingrad. In fact, head of Army General Staff General Franz Halder had been dismissed in September after his efforts to warn about the danger, developing along the over-extended flanks of the Sixth Army and the Fourth Panzer Army.
As early as September the Soviet Stavka began planning a series of counteroffensives to encompass the destruction of German forces in the south, fighting in Stalingrad and in the Caucasus, against Army Group Center. Command of Soviet efforts to relieve Stalingrad was put under the leadership of General Aleksandr Vasilevsky; the Stavka developed two major operations to be conducted against Axis forces near Stalingrad and Saturn, planned for Operation Mars, designed to engage German Army Group Center in an effort to distract reinforcements and to inflict as much damage as possible. Operation Uranus involved the use of large Soviet mechanized and infantry forces to encircle German and other Axis forces directly around Stalingrad; as preparations for the offensive commenced, the attack's starting points were positioned on stretches of front to the rear of the German Sixth Army preventing the Germans from reinforcing those sectors where Axis units were too overstretched to occupy effectively. The offensive was a double envel
Budapest is the capital and the most populous city of Hungary, the tenth-largest city in the European Union by population within city limits. The city had an estimated population of 1,752,704 in 2016 distributed over a land area of about 525 square kilometres. Budapest is both a city and county, forms the centre of the Budapest metropolitan area, which has an area of 7,626 square kilometres and a population of 3,303,786, comprising 33 percent of the population of Hungary; the history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century; the area was pillaged by the Mongols in 1241. Buda, the settlements on the west bank of the river, became one of the centres of Renaissance humanist culture by the 15th century; the Battle of Mohács in 1526 was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the region entered a new age of prosperity.
Pest-Buda became a global city with the unification of Buda, Óbuda, Pest on 17 November 1873, with the name'Budapest' given to the new capital. Budapest became the co-capital of the Austro-Hungarian Empire, a great power that dissolved in 1918, following World War I; the city was the focal point of the Hungarian Revolution of 1848, the Battle of Budapest in 1945, the Hungarian Revolution of 1956. Budapest is an Alpha − global city with strengths in commerce, media, fashion, technology and entertainment, it is Hungary's financial centre and the highest ranked Central and Eastern European city on Innovation Cities Top 100 index, as well ranked as the second fastest-developing urban economy in Europe. Budapest is the headquarters of the European Institute of Innovation and Technology, the European Police College and the first foreign office of the China Investment Promotion Agency. Over 40 colleges and universities are located in Budapest, including the Eötvös Loránd University, the Semmelweis University and the Budapest University of Technology and Economics.
Opened in 1896, the city's subway system, the Budapest Metro, serves 1.27 million, while the Budapest Tram Network serves 1.08 million passengers daily. Budapest is cited as one of the most beautiful cities in Europe, ranked as "the world's second best city" by Condé Nast Traveler, "Europe's 7th most idyllic place to live" by Forbes. Among Budapest's important museums and cultural institutions is the Museum of Fine Arts. Further famous cultural institutions are the Hungarian National Museum, House of Terror, Franz Liszt Academy of Music, Hungarian State Opera House and National Széchényi Library; the central area of the city along the Danube River is classified as a UNESCO World Heritage Site and has many notable monuments, including the Hungarian Parliament, Buda Castle, Fisherman's Bastion, Gresham Palace, Széchenyi Chain Bridge, Matthias Church and the Liberty Statue. Other famous landmarks include Andrássy Avenue, St. Stephen's Basilica, Heroes' Square, the Great Market Hall, the Nyugati Railway Station built by the Eiffel Company of Paris in 1877 and the second-oldest metro line in the world, the Millennium Underground Railway.
The city has around 80 geothermal springs, the largest thermal water cave system, second largest synagogue, third largest Parliament building in the world. Budapest attracts 4.4 million international tourists per year, making it a popular destination in Europe. The separate towns of Buda, Óbuda, Pest were in 1873 unified and given the new name Budapest. Before this, the towns together had sometimes been referred to colloquially as "Pest-Buda". Pest has been sometimes used colloquially as a shortened name for Budapest. All varieties of English pronounce the -s- as in the English word pest; the -u in Buda- is pronounced either /u/ like food or /ju/ like cue. In Hungarian, the -s- is pronounced /ʃ/ as in wash; the origins of the names "Buda" and "Pest" are obscure. The first name comes from: Buda was the name of the first constable of the fortress built on the Castle Hill in the 11th century or a derivative of Bod or Bud, a personal name of Turkic origin, meaning'twig'. or a Slavic personal name, the short form of Budimír, Budivoj.
Linguistically, however, a German origin through the Slavic derivative вода is not possible, there is no certainty that a Turkic word comes from the word buta ~ buda'branch, twig'. According to a legend recorded in chronicles from the Middle Ages, "Buda" comes from the name of its founder, brother of Hunnic ruler Attila. There are several theories about Pest. One states that the name derives from Roman times, since there was a local fortress called by Ptolemaios "Pession". Another has it that Pest originates in the Slavic word for пещера, or peštera. A third cites pešt, referencing a cave where fires burned or a limekiln; the first settlement on the territory of Budapest was built by Celts before 1 AD. It was occupied by the Romans; the Roman settlement – Aquincum – became the main city of Pannonia Inferior in 106 AD. At first it was a military settlement, the city rose around it, making it the focal point of the city's commercial life. Today this area corresponds to the Óbuda district within Budapest.
The Romans constructed roads, amphitheaters and houses with heated floors in this fortified military camp. The Roman city of Aquincum is the best-conserved of the Roman sites in Hungary; the archaeological site was turned into a museum with open-air sections. The Magyar tribes led by Árpád, forc
