Hungary Pecs 2005 June 068

Hungary ( hu, Magyarország ) is a landlocked country in Central Europe. Spanning of the Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. Hungary has a population of nearly 9 million, mostly ethnic Hungarians and a significant Romani minority. Hungarian, the official language, is the world's most widely spoken Uralic language and among the few non- Indo-European languages widely spoken in Europe. Budapest is the country's capital and largest city; other major urban areas include Debrecen, Szeged, Miskolc, Pécs, and Győr.

The territory of present-day Hungary has for centuries been a crossroads for various peoples, including Celts, Romans, Germanic tribes, Huns, West Slavs and the Avars. The foundation of the Hungarian state was established in the late 9th century AD with the conquest of the Carpathian Basin by Hungarian grand prince Árpád. His great-grandson Stephen I ascended the throne in 1000, converting his realm to a Christian kingdom. By the 12th century, Hungary became a regional power, reaching its cultural and political height in the 15th century. Following the Battle of Mohács in 1526, it was partially occupied by the Ottoman Empire (1541–1699). Hungary came under Habsburg rule at the turn of the 18th century, later joining with the Austrian Empire to form Austria-Hungary, a major power into the early 20th century.

Austria-Hungary collapsed after World War I, and the subsequent Treaty of Trianon established Hungary's current borders, resulting in the loss of 71% of its territory, 58% of its population, and 32% of ethnic Hungarians. Following the tumultuous interwar period, Hungary joined the Axis powers in World War II, suffering significant damage and casualties.''Hungary: The Unwilling Satellite''
Devin-Adair Company, New York, 1947. Reprint: Simon Publications, 2002.Thomas, ''The Royal Hungarian Army in World War II'', pg. 11 Postwar Hungary became a satellite state of the Soviet Union, leading to the establishment of the Hungarian People's Republic. Following the failed 1956 revolution, Hungary became a comparatively freer, though still repressive, member of the Eastern Bloc. The removal of Hungary's border fence with Austria accelerated the collapse of the Eastern Bloc and subsequently the Soviet Union. On 23 October 1989, Hungary again became a democratic parliamentary republic. Hungary joined the European Union in 2004 and has been part of the Schengen Area since 2007. Since the Second Orbán Government in 2010, the country has undergone significant democratic backsliding, and is now considered by some to be an authoritarian polity.

Hungary is a middle power in international affairs, owing mostly to its cultural and economic influence. It is a high-income economy with a very high human development index, where citizens enjoy universal health care and tuition-free secondary education. Hungary has a long history of significant contributions to arts, music, literature, sports, science and technology.''Hungarian literature – ”Popular poetry is the only real poetry was the opinion of Sándor Petőfi, one of the greatest Hungarian poets, whose best poems rank among the masterpieces of world literature”''.
''Encyclopædia Britannica'', 2012 edition It is a popular tourist destination in Europe, drawing 24.5 million international tourists in 2019. It is a member of numerous international organisations, including the Council of Europe, NATO, United Nations, World Health Organization, World Trade Organization, World Bank, International Investment Bank, Asian Infrastructure Investment Bank, and the Visegrád Group.

Etymology

The "H" in the name of Hungary (and Latin ''Hungaria'') is most likely derived from historical associations with the Huns, who had settled Hungary prior to the Avars. The rest of the word comes from the Latinised form of Byzantine Greek ''Oungroi'' (Οὔγγροι). The Greek name might be borrowed from Old Bulgarian ''ągrinŭ'', in turn borrowed from Oghur-Turkic '' Onogur'' ('ten ribes of theOgurs'), perhaps entering Slavic through a dialectal *Ongur. '' Onogur'' was the collective name for the tribes who later joined the Bulgar tribal confederacy that ruled the eastern parts of Hungary after the Avars. Peter B. Golden also considers Árpád Berta's theory, who has suggested that the name derives from Khazar Turkic ongar (oŋ "right," oŋar- "to make something better, to put (it) right," oŋgar-  “to make something better, to put (it) right,” oŋaru “towards the right") “rightwing”. This points to the idea that the pre-Conquest Magyar Union formed the "right wing" (= western wing) of the Khazar military forces.

The Hungarian endonym is ''Magyarország'', composed of ''magyar'' ('Hungarian') and ''ország'' ('country'). The name "Magyar", which refers to the people of the country, more accurately reflects the name of the country in some other languages such as Turkish, Persian and other languages as ''Magyaristan'' or ''Land of Magyars'' or similar. The word ''magyar'' is taken from the name of one of the seven major semi-nomadic Hungarian tribes, ''magyeri''. The first element ''magy'' is likely from proto-Ugric *''mäńć-'' 'man, person', also found in the name of the Mansi people (''mäńćī, mańśi, måńś''). The second element ''eri'', 'man, men, lineage', survives in Hungarian ''férj'' 'husband', and is cognate with Mari ''erge'' 'son', Finnish archaic ''yrkä'' 'young man'.

History

Before 895

The Roman Empire conquered the territory between the Alps and the area west of the Danube River from 16 to 15 BC, the Danube being the frontier of the empire.Kershaw, Stephen P. (2013). ''A Brief History of The Roman Empire: Rise and Fall. London.'' Constable & Robinson Ltd. ISBN 978-1-78033-048-8. In 14 BC, Pannonia, the western part of the Carpathian Basin, which includes today's west of Hungary, was recognised by emperor Augustus in the '' Res Gestae Divi Augusti'' as part of the Roman Empire. The area south-east of Pannonia was organised as the Roman province Moesia in 6 BC. An area east of the river Tisza became the Roman province of Dacia in 106 AD, which included today's east Hungary. It remained under Roman rule until 271.Scarre, Chris (2012). ''Chronicle of the Roman Emperors: The Reign-by-Reign Record of the Rulers of Imperial Rome.'' London. Thames & Hudson Ltd. ISBN 978-0-500-28989-1. From 235, the Roman Empire went through troubled times, caused by revolts, rivalry and rapid succession of emperors. The Western Roman Empire collapsed in the 5th century under the stress of the migration of Germanic tribes and Carpian pressure.

This period brought many invaders into Central Europe, beginning with the Hunnic Empire (c. 370–469). The most powerful ruler of the Hunnic Empire was Attila the Hun (434–453), who later became a central figure in Hungarian mythology.Kelly, Christopher (2008). ''Attila The Hun: Barbarian Terror and The Fall of The Roman Empire.'' London. The Bodley Head. ISBN 978-0-224-07676-0. After the disintegration of the Hunnic Empire, the Gepids, an Eastern Germanic tribe, who had been vassalised by the Huns, established their own kingdom in the Carpathian Basin. Other groups which reached the Carpathian Basin during the Migration Period were the Goths, Vandals, Lombards, and Slavs.

In the 560s, the Avars founded the Avar Khaganate, a state that maintained supremacy in the region for more than two centuries. The Franks under Charlemagne defeated the Avars in a series of campaigns during the 790s.Lajos Gubcsi

By the mid-9th century, the Balaton Principality, also known as Lower Pannonia, was established west of the Danube as part of the Frankish March of Pannonia.Luthar, Oto, ed. (2008).

Middle Ages (895–1526)

The freshly unified Hungarians led by Árpád (by tradition a descendant of Attila), settled in the Carpathian Basin starting in 895. According to the Finno-Ugrian theory, they originated from an ancient Uralic-speaking population that formerly inhabited the forested area between the Volga River and the Ural Mountains. As a federation of united tribes, Hungary was established in 895, some 50 years after the division of the Carolingian Empire at the Treaty of Verdun in 843, before the unification of the Anglo-Saxon kingdoms.

Initially, the rising Principality of Hungary ("Western Tourkia" in medieval Greek sources) was a state created by a semi-nomadic people. It accomplished an enormous transformation into a Christian realm during the 10th century. This state was well-functioning, and the nation's military power allowed the Hungarians to conduct successful fierce campaigns and raids, from Constantinople to as far as today's Spain. The Hungarians defeated no fewer than three major East Frankish imperial armies between 907 and 910. A defeat at the Battle of Lechfeld in 955 signaled a provisory end to most campaigns on foreign territories, at least towards the west.

Age of Árpádian kings

In 972 the ruling prince ( hu, fejedelem) Géza of the Árpád dynasty officially started to integrate Hungary into Christian Western Europe. His first-born son, Saint Stephen I, became the first King of Hungary after defeating his pagan uncle Koppány, who also claimed the throne. Under Stephen, Hungary was recognised as a Catholic Apostolic Kingdom. Applying to Pope Sylvester II, Stephen received the insignia of royalty (including probably a part of the Holy Crown of Hungary, currently kept in the Hungarian Parliament) from the papacy.

By 1006, Stephen consolidated his power and started sweeping reforms to convert Hungary into a Western feudal state. The country switched to using Latin for administration purposes, and until as late as 1844, Latin remained the official language of administration. Around this time, Hungary began to become a powerful kingdom. Ladislaus I extended Hungary's frontier in Transylvania and invaded Croatia in 1091. The Croatian campaign culminated in the Battle of Gvozd Mountain in 1097 and a personal union of Croatia and Hungary in 1102, ruled by Coloman.

The most powerful and wealthiest king of the Árpád dynasty was Béla III, who disposed of the equivalent of 23 tonnes of silver per year. This exceeded the income of the French king (estimated at 17 tonnes) and was double the receipts of the English Crown. Andrew II issued the '' Diploma Andreanum'' which secured the special privileges of the Transylvanian Saxons and is considered the first autonomy law in the world. He led the Fifth Crusade to the Holy Land in 1217, setting up the largest royal army in the history of Crusades. His Golden Bull of 1222 was the first constitution in Continental Europe. The lesser nobles also began to present Andrew with grievances, a practice that evolved into the institution of the parliament (''parlamentum publicum'').

In 1241–1242, the kingdom received a major blow with the Mongol (Tatar) invasion. Up to half of Hungary's population of 2 million were victims of the invasion. King Béla IV let Cumans and Jassic people into the country, who were fleeing the Mongols. Over the centuries, they were fully assimilated into the Hungarian population. After the Mongols retreated, King Béla ordered the construction of hundreds of stone castles and fortifications, to defend against a possible second Mongol invasion. The Mongols returned to Hungary in 1285, but the newly built stone-castle systems and new tactics (using a higher proportion of heavily armed knights) stopped them. The invading Mongol force was defeated near Pest by the royal army of King Ladislaus IV. As with later invasions, it was repelled handily, the Mongols losing much of their invading force.

Age of elected kings

The Kingdom of Hungary reached one of its greatest extents during the Árpádian kings, yet royal power was weakened at the end of their rule in 1301. After a destructive period of interregnum (1301–1308), the first Angevin king, Charles I of Hungary – a bilineal descendant of the Árpád dynasty – successfully restored royal power and defeated oligarch rivals, the so-called "little kings". The second Angevin Hungarian king, Louis the Great (1342–1382), led many successful military campaigns from Lithuania to southern Italy (Kingdom of Naples) and was also king of Poland from 1370. After King Louis died without a male heir, the country was stabilised only when Sigismund of Luxembourg (1387–1437) succeeded to the throne, who in 1433 also became Holy Roman Emperor. Sigismund was also (in several ways) a bilineal descendant of the Árpád dynasty.

The first Hungarian Bible translation was completed in 1439. For half a year in 1437, there was an antifeudal and anticlerical peasant revolt in Transylvania which was strongly influenced by Hussite ideas.

From a small noble family in Transylvania, John Hunyadi grew to become one of the country's most powerful lords, thanks to his outstanding capabilities as a mercenary commander. He was elected governor, then regent. He was a successful crusader against the Ottoman Turks, one of his greatest victories being the siege of Belgrade in 1456.

The last strong king of medieval Hungary was the Renaissance king Matthias Corvinus (1458–1490), son of John Hunyadi. His election was the first time that a member of the nobility mounted to the Hungarian royal throne without dynastic background. He was a successful military leader and an enlightened patron of the arts and learning. His library, the Bibliotheca Corviniana, was Europe's greatest collection of historical chronicles, philosophic and scientific works in the 15th century, and second only in size to the Vatican Library. Items from the Bibliotheca Corviniana were inscribed on UNESCO's Memory of the World Register in 2005. The serfs and common people considered him a just ruler because he protected them from excessive demands and other abuses by the magnates. Under his rule, in 1479, the Hungarian army destroyed the Ottoman and Wallachian troops at the Battle of Breadfield. Abroad he defeated the Polish and German imperial armies of Frederick at Breslau ( Wrocław). Matthias' mercenary standing army, the Black Army of Hungary, was an unusually large army for its time, and it conquered Vienna as well as parts of Austria and Bohemia.

Decline (1490–1526)

King Matthias died without lawful sons, and the Hungarian magnates procured the accession of the Pole Vladislaus II (1490–1516), supposedly because of his weak influence on Hungarian aristocracy. Hungary's international role declined, its political stability was shaken, and social progress was deadlocked. In 1514, the weakened old King Vladislaus II faced a major peasant rebellion led by György Dózsa, which was ruthlessly crushed by the nobles, led by John Zápolya. The resulting degradation of order paved the way for Ottoman pre-eminence. In 1521, the strongest Hungarian fortress in the South, Nándorfehérvár (today's Belgrade, Serbia), fell to the Turks. The early appearance of Protestantism further worsened internal relations in the country.

Ottoman wars (1526–1699)

After some 150 years of wars with the Hungarians and other states, the Ottomans gained a decisive victory over the Hungarian army at the Battle of Mohács in 1526, where King Louis II died while fleeing. Amid political chaos, the divided Hungarian nobility elected two kings simultaneously, John Zápolya and Ferdinand I of the Habsburg dynasty. With the conquest of Buda by the Turks in 1541, Hungary was divided into three parts and remained so until the end of the 17th century. The north-western part, termed as Royal Hungary, was annexed by the Habsburgs who ruled as kings of Hungary. The eastern part of the kingdom became independent as the Principality of Transylvania, under Ottoman (and later Habsburg) suzerainty. The remaining central area, including the capital Buda, was known as the Pashalik of Buda.

The vast majority of the seventeen and nineteen thousand Ottoman soldiers in service in the Ottoman fortresses in the territory of Hungary were Orthodox and Muslim Balkan Slavs rather than ethnic Turkish people. Orthodox Southern Slavs were also acting as akinjis and other light troops intended for pillaging in the territory of present-day Hungary. In 1686, the Holy League's army, containing over 74,000 men from various nations, reconquered Buda from the Turks. After some more crushing defeats of the Ottomans in the next few years, the entire Kingdom of Hungary was removed from Ottoman rule by 1718. The last raid into Hungary by the Ottoman vassals Tatars from Crimea took place in 1717. The constrained Habsburg Counter-Reformation efforts in the 17th century reconverted the majority of the kingdom to Catholicism. The ethnic composition of Hungary was fundamentally changed as a consequence of the prolonged warfare with the Turks. A large part of the country became devastated, population growth was stunted, and many smaller settlements perished. The Austrian-Habsburg government settled large groups of Serbs and other Slavs in the depopulated south, and settled Germans (called Danube Swabians) in various areas, but Hungarians were not allowed to settle or re-settle in the south of the Carpathian Basin.

From the 18th century to World War I (1699–1918)

Between 1703 and 1711, there was a large-scale war of independence led by Francis II Rákóczi, who after the dethronement of the Habsburgs in 1707 at the Diet of Ónod, took power provisionally as the ruling prince for the wartime period, but refused the Hungarian crown and the title "king". The uprisings lasted for years. The Hungarian Kuruc army, although taking over most of the country, lost the main battle at Trencsén (1708). Three years later, because of the growing desertion, defeatism, and low morale, the Kuruc forces finally surrendered.

During the Napoleonic Wars and afterward, the Hungarian Diet had not convened for decades. In the 1820s, the emperor was forced to convene the Diet, which marked the beginning of a Reform Period (1825–1848, hu, reformkor). Count István Széchenyi, one of the most prominent statesmen of the country, recognised the urgent need for modernisation and his message got through. The Hungarian Parliament was reconvened in 1825 to handle financial needs. A liberal party emerged and focused on providing for the peasantry. Lajos Kossuth—a famous journalist at that time—emerged as a leader of the lower gentry in the Parliament. A remarkable upswing started as the nation concentrated its forces on modernisation even though the Habsburg monarchs obstructed all important liberal laws relating to civil and political rights and economic reforms. Many reformers (Lajos Kossuth, Mihály Táncsics) were imprisoned by the authorities.

On 15 March 1848, mass demonstrations in Pest and Buda enabled Hungarian reformists to push through a list of 12 demands. Under Governor and President Lajos Kossuth and Prime Minister Lajos Batthyány, the House of Habsburg was dethroned. The Habsburg ruler and his advisors skillfully manipulated the Croatian, Serbian and Romanian peasantry, led by priests and officers firmly loyal to the Habsburgs, and induced them to rebel against the Hungarian government, though the Hungarians were supported by the vast majority of the Slovak, German and Rusyn nationalities and by all the Jews of the kingdom, as well as by a large number of Polish, Austrian and Italian volunteers. In July 1849 the Hungarian Parliament proclaimed and enacted the first laws of ethnic and minority rights in the world. Many members of the nationalities gained the coveted highest positions within the Hungarian Army, like General János Damjanich, an ethnic Serb who became a Hungarian national hero through his command of the 3rd Hungarian Army Corps or Józef Bem, who was Polish and also became a national hero in Hungary. The Hungarian forces ('' Honvédség'') defeated Austrian armies. To counter the successes of the Hungarian revolutionary army, Habsburg Emperor Franz Joseph I asked for help from the "Gendarme of Europe", Tsar Nicholas I, whose Russian armies invaded Hungary. This made Artúr Görgey surrender in August 1849. The leader of the Austrian army, Julius Jacob von Haynau, became governor of Hungary for a few months and ordered the execution of the 13 Martyrs of Arad, leaders of the Hungarian army, and Prime Minister Batthyány in October 1849. Kossuth escaped into exile. Following the war of 1848–1849, the whole country was in "passive resistance".

Because of external and internal problems, reforms seemed inevitable, and major military defeats of Austria forced the Habsburgs to negotiate the Austro-Hungarian Compromise of 1867, by which the dual monarchy of Austria-Hungary was formed. This empire had the second largest area in Europe (after the Russian Empire), and it was the third most populous (after Russia and the German Empire). The two realms were governed separately by two parliaments from two capital cities, with a common monarch and common external and military policies. Economically, the empire was a customs union. The old Hungarian Constitution was restored, and Franz Joseph I was crowned as King of Hungary. The era witnessed impressive economic development. The formerly backward Hungarian economy became relatively modern and industrialised by the turn of the 20th century, although agriculture remained dominant until 1890. In 1873, the old capital Buda and Óbuda were officially united with Pest, thus creating the new metropolis of Budapest. Many of the state institutions and the modern administrative system of Hungary were established during this period.

After the assassination of Archduke Franz Ferdinand in Sarajevo, Prime Minister István Tisza and his cabinet tried to avoid the outbreak and escalating of a war in Europe, but their diplomatic efforts were unsuccessful. Austria-Hungary drafted 9 million (fighting forces: 7.8 million) soldiers in World War I (over 4 million from the Kingdom of Hungary) on the side of Germany, Bulgaria, and Turkey. The troops raised in the Kingdom of Hungary spent little time defending the actual territory of Hungary, with the exceptions of the Brusilov offensive in June 1916 and a few months later when the Romanian army made an attack into Transylvania, both of which were repelled. The Central Powers conquered Serbia. Romania declared war. The Central Powers conquered southern Romania and the Romanian capital Bucharest. In 1916 Emperor Joseph died, and the new monarch Charles IV sympathised with the pacifists. With great difficulty, the Central Powers stopped and repelled the attacks of the Russian Empire.

The Eastern Front of the Allied (Entente) Powers completely collapsed. The Austro-Hungarian Empire then withdrew from all defeated countries. On the Italian front, the Austro-Hungarian army made no progress against Italy after January 1918. Despite great success on the Eastern Front, Germany suffered complete defeat on the Western Front. By 1918, the economic situation had deteriorated (strikes in factories were organised by leftist and pacifist movements) and uprisings in the army had become commonplace. In the capital cities, the Austrian and Hungarian leftist liberal movements (the maverick parties) and their leaders supported the separatism of ethnic minorities. Austria-Hungary signed a general armistice in Padua on 3 November 1918. In October 1918, Hungary's union with Austria was dissolved.

Between the World Wars (1918–1941)

Following the First World War, Hungary underwent a period of profound political upheaval, beginning with the Aster Revolution in 1918, which brought the social-democratic Mihály Károlyi to power as prime minister. The Hungarian Royal Honvéd army still had more than 1,400,000 soldiers when Károlyi was installed. Károlyi yielded to U.S. President Woodrow Wilson's demand for pacifism by ordering the disarmament of the Hungarian army. This happened under the direction of Béla Linder, minister of war in the Károlyi government.Dixon J. C

Palgrave Macmillan 2008. p. 156. Disarmament of its army meant that Hungary was to remain without a national defence at a time of particular vulnerability. During the rule of Károlyi's pacifist cabinet, Hungary lost control over approximately 75% of its former pre-WW1 territories () without a fight and was subject to foreign occupation. The Little Entente, sensing an opportunity, invaded the country from three sides— Romania invaded Transylvania, Czechoslovakia annexed Upper Hungary (today's Slovakia), and a joint Serb-French coalition annexed Vojvodina and other southern regions. In March 1919, communists led by Béla Kun ousted the Károlyi government and proclaimed the Hungarian Soviet Republic (''Tanácsköztársaság''), followed by a thorough Red Terror campaign. Despite some successes on the Czechoslovak front, Kun's forces were ultimately unable to resist the Romanian invasion; by August 1919, Romanian troops occupied Budapest and ousted Kun.

In November 1919, rightist forces led by former Austro-Hungarian admiral Miklós Horthy entered Budapest; exhausted by the war and its aftermath, the populace accepted Horthy's leadership. In January 1920, parliamentary elections were held, and Horthy was proclaimed regent of the reestablished Kingdom of Hungary, inaugurating the so-called "Horthy era" (''Horthy-kor''). The new government worked quickly to normalise foreign relations while turning a blind eye to a White Terror that swept through the countryside; extrajudicial killings of suspected communists and Jews lasted well into 1920. On 4 June 1920, the Treaty of Trianon established new borders for Hungary. The country lost 71% of its territory and 66% of its pre-war population, as well as many sources of raw materials and its sole port at Fiume. Though the revision of the treaty quickly rose to the top of the national political agenda, the Horthy government was not willing to resort to military intervention to do so.

The initial years of the Horthy regime were preoccupied with putsch attempts by Charles IV, the Austro-Hungarian pretender; continued suppression of communists; and a migration crisis triggered by the Trianon territorial changes. Though free elections continued, Horthy's personality and those of his personally selected prime ministers dominated the political scene. The government's actions continued to drift right with the passage of antisemitic laws and, because of the continued isolation of the Little Entente, economic and then political gravitation towards Italy and Germany. The Great Depression further exacerbated the situation, and the popularity of fascist politicians increased, such as Gyula Gömbös and Ferenc Szálasi, promising economic and social recovery.

Horthy's nationalist agenda reached its apogee in 1938 and 1940, when the Nazis rewarded Hungary's staunchly pro-Germany foreign policy in the First and Second Vienna Awards, peacefully restoring ethnic-Hungarian-majority areas lost after Trianon. In 1939, Hungary regained further territory from Czechoslovakia through force. Hungary formally joined the Axis powers on 20 November 1940 and in 1941 participated in the invasion of Yugoslavia, gaining some of its former territories in the south.

World War II (1941–1945)

Hungary formally entered World War II as an Axis power on 26 June 1941, declaring war on the Soviet Union after unidentified planes bombed Kassa, Munkács, and Rahó. Hungarian troops fought on the Eastern Front for two years. Despite early success at the Battle of Uman,J. Lee Ready (1995), ''World War Two. Nation by Nation'', London, Cassell, page 130. the government began seeking a secret peace pact with the Allies after the Second Army suffered catastrophic losses at the River Don in January 1943. Learning of the planned defection, German troops occupied Hungary on 19 March 1944 to guarantee Horthy's compliance. In October, as the Soviet front approached, and the government made further efforts to disengage from the war, German troops ousted Horthy and installed a puppet government under Szálasi's fascist Arrow Cross Party. Szálasi pledged all the country's capabilities in service of the German war machine. By October 1944, the Soviets had reached the river Tisza, and despite some losses, succeeded in encircling and besieging Budapest in December.

After German occupation, Hungary participated in the Holocaust. During the German occupation in May–June 1944, the Arrow Cross and Hungarian police deported nearly 440,000 Jews, mainly to Auschwitz. Nearly all of them were murdered. The Swedish Diplomat Raoul Wallenberg managed to save a considerable number of Hungarian Jews by giving them Swedish passports. Rezső Kasztner, one of the leaders of the Hungarian Aid and Rescue Committee, bribed senior SS officers such as Adolf Eichmann
