The Kingdom of Hungary was a monarchy in Central Europe that existed for nearly a millennium, from 1000 to 1946. The Catholic kingdom emerged as a continuation of the Grand Principality of Hungary upon the coronation of the first king Stephen I at Esztergom around 1000; his family (the Árpád dynasty) led the monarchy for 300 years. By the 12th century, the kingdom had become a European power.
Due to the Ottoman occupation of the central and southern territories of Hungary in the 16th century, the country was partitioned into three parts: the Habsburg Royal Hungary, Ottoman Hungary, and the semi-independent Principality of Transylvania. The House of Habsburg held the Hungarian throne after the Battle of Mohács in 1526 continuously until 1918 and also played a key role in the wars against the Ottoman Empire and the eventual expulsion of the Turks during and after the Great Turkish War.
The Hungarians fought many wars of independence against the Habsburgs, including in 1604–06, 1664–71, 1680–85, 1703–11, and 1848–49. From 1867, territories connected to the Hungarian crown were incorporated into Austria-Hungary under the name of Lands of the Crown of Saint Stephen. The monarchy ended with the deposition of the last king Charles IV in 1918, after which Hungary became a republic. The kingdom was nominally restored during the "Regency" of 1920–46, ending under the Soviet occupation in 1946.
The Kingdom of Hungary was a multiethnic state from its inception until the Treaty of Trianon and it covered what is today Hungary, Slovakia, Transylvania and other parts of Romania, Carpathian Ruthenia (now part of Ukraine), Vojvodina (now part of Serbia), the territory of Burgenland (now part of Austria), Međimurje (now part of Croatia), Prekmurje (now part of Slovenia) and a few villages which are now part of Poland. From 1102, it also included the Kingdom of Croatia, being in personal union with it, united under the King of Hungary.
According to Hungarian demographers, about 80 percent of the population was made up of Hungarians before the Battle of Mohács, however in the mid-19th century out of a population of 14 million less than 6 million were Hungarian due to the resettlement policies and continuous immigration from neighboring countries. The loss of 72% of Hungary as a result of the post-World War I Treaty of Trianon (reinforced by the post-World War II Treaty of Paris) made the remnant of Hungary ethnically homogeneous. More than nine-tenths of the population of modern Hungary is ethnically Hungarian and speaks Hungarian as their mother tongue.
Today, the feast day of the first king Stephen I (20 August) is a national holiday in Hungary, commemorating the foundation of the state (Foundation Day).
The Latin forms Regnum Hungariae or Ungarie (Regnum meaning kingdom); Regnum Marianum (Kingdom of Mary); or simply Hungaria, were the names used in official documents in Latin from the beginning of the kingdom to the 1840s.
The German name (Königreich Ungarn) was used officially from 1784 to 1790; it was used again between 1849 and the 1860s.
The Hungarian name (Magyar Királyság) was used in the 1840s, and then again from the 1860s to 1946. The unofficial Hungarian name of the kingdom was Magyarország, which is still the colloquial, and also the official name of Hungary.
The names in the other native languages of the kingdom were: Polish: Królestwo Węgier, Romanian: Regatul Ungariei, Serbian: Kraljevina Ugarska, Croatian: Kraljevina Ugarska, Slovene: Kraljevina Ogrska, Slovak: Uhorské kráľovstvo, and Italian (for the city of Fiume), Regno d'Ungheria.
In Austria-Hungary (1867–1918), the unofficial name Transleithania was sometimes used to denote the regions of the Kingdom of Hungary. Officially, the term Lands of the Crown of Saint Stephen was included for the Hungarian part of Austria-Hungary, although this term was also in use prior to that time.
The Hungarians, led by Árpád (who might have been either their sacred ruler known as a kende or their military leader known as a gyula), settled the Carpathian Basin in 895 and established the Principality of Hungary (896–1000). The Hungarians led several successful incursions to Western Europe, until they were stopped by Otto I, Holy Roman Emperor in Battle of Lechfeld.
The principality was succeeded by the Christian Kingdom of Hungary with the coronation of St Stephen I (son of principal Géza. Originally called Vajk until baptized) at Esztergom on Christmas Day 1000. The first kings of the kingdom were from the Árpád dynasty. He fought against Koppány and in 998, with Bavarian help, defeated him near Veszprém. The Catholic Church received powerful support from Stephen I, who with Christian Hungarians and German knights wanted a Christian kingdom established in Central Europe. Stephen I of Hungary was canonized as a Catholic saint in 1083 and an Eastern Orthodox saint in 2000.
Around the 11th century, the Kingdom of Hungary became a Christian state, and Catholicism in the Hungarian Kingdom was a state religion.
After his death, a period of revolts and conflict for supremacy ensued between the royalty and the nobles. In 1051, armies of the Holy Roman Empire tried to conquer Hungary, but they were defeated at Vértes Mountain. The armies of the Holy Roman Empire continued to suffer defeats; the second greatest battle was at the town now called Bratislava, in 1052. Before 1052, Peter Orseolo, a supporter of the Holy Roman Empire, was overthrown by king Samuel Aba of Hungary.
This period of revolts ended during the reign of Béla I. Hungarian chroniclers praised Béla I for introducing new currency, such as the silver denarius, and for his benevolence to the former followers of his nephew, Solomon. He was succeeded by Ladislaus I of Hungary, who further stabilized and strengthened the kingdom. He was also canonized as a saint. Under his rule Hungarians successfully fought against the Cumans and acquired parts of Croatia in 1091. Due to a dynastic crisis in Croatia, with the help of the local nobility who supported his claim, he managed to swiftly seize power in northern parts of the Croatian kingdom (Slavonia), as he was a claimant to the throne due to the fact that his sister was married to the late Croatian king Zvonimir who died without an heir.
However, kingship over all of Croatia would not be achieved until the reign of his successor Coloman. With the coronation of King Coloman as "King of Croatia and Dalmatia" in Biograd in 1102, the two kingdoms of Croatia and Hungary were united under one crown. Although the precise terms of this relationship became a matter of dispute in the 19th century, it is believed that Coloman created a kind of personal union between the two kingdoms. The nature of the relationship varied through time, Croatia retained a large degree of internal autonomy overall, while the real power rested in the hands of the local nobility. Modern Croatian and Hungarian historiographies mostly view the relations between Kingdom of Croatia (1102–1526) and Kingdom of Hungary from 1102 as a form of a personal union, i.e. that they were connected by a common king. Also, one of the greatest Hungarian jurists and statesmen of the 16th century, István Werbőczy in his work Tripartitum treats Croatia as a kingdom separate to Hungary.
Especially Arabic and Byzantine travelers from this time praised the richness country, the dense pastures, the nicely cultivated lands, the plentiful animals in waters and forests. They said that the wheat is cheap, the markets are populous, the cities flourish and the folk are wealthy. Although it is hardly credible that they refer to all layers of society, the documents were inspired by the reality.
