Kingdom of Hungary in the context of "Suleiman the Magnificent"

Romania is a country located at the crossroads of Central, Eastern and Southeast Europe. It borders Ukraine to the north and east, Hungary to the west, Serbia to the southwest, Bulgaria to the south, Moldova to the east, and the Black Sea to the southeast. It has a mainly continental climate, and an area of 238,397 km (92,046 sq mi) with a population of 19 million people. Romania is the twelfth-largest country in Europe and the sixth-most populous member state of the European Union. Europe's second-longest river, the Danube, empties into the Danube Delta in the southeast of the country. The Carpathian Mountains cross Romania from the north to the southwest and include Moldoveanu Peak, at an altitude of 2,544 m (8,346 ft). Bucharest is the country's capital, largest urban area, and financial centre. Other major urban areas include Cluj-Napoca, Timișoara, Iași, Constanța and Brașov.

Settlement in the territory of modern Romania began in the Lower Paleolithic, later becoming the Dacian Kingdom before Roman conquest and Romanisation. The modern Romanian state was formed in 1859 with the unification of Moldavia and Wallachia under Alexandru Ioan Cuza, becoming the Kingdom of Romania in 1881 under Carol I of Romania. Romania gained independence from the Ottoman Empire in 1877, formalised by the Treaty of Berlin. After World War I, Transylvania, Banat, Bukovina, and Bessarabia joined the Old Kingdom, forming Greater Romania, which reached its largest territorial extent. In 1940, under Axis pressure, Romania lost territories to Hungary, Bulgaria, and the Soviet Union. Following the 1944 Romanian coup d'état, Romania switched sides to join the Allies. After World War II, it regained Northern Transylvania through the Paris Peace Treaties. Under Soviet occupation, King Michael I was forced to abdicate, and Romania became a socialist republic and Warsaw Pact member. After the uniquely violent Romanian revolution in December 1989, Romania began a transition to liberal democracy and a market economy.

The House of Wittelsbach (German: Haus Wittelsbach) is a former Bavarian dynasty, with branches that have ruled over territories including the Electorate of Bavaria, the Electoral Palatinate, the Electorate of Cologne, Holland, Zeeland, Sweden (with Swedish-ruled Finland), Denmark, Norway, Hungary, Bohemia, and Greece. Their ancestral lands of Bavaria and the Palatinate were prince-electorates, and the family had three of its members elected emperors and kings of the Holy Roman Empire. They ruled over the Kingdom of Bavaria which was created in 1805 and continued to exist until 1918.

The House of Windsor, the reigning royal house of the British monarchy, are descendants of Sophia of Hanover (1630–1714), a Wittelsbach Princess of the Palatinate by birth and Electress of Hanover by marriage, who had inherited the succession rights of the House of Stuart and passed them on to the House of Hanover.

The High Middle Ages, or High Medieval Period, was the period of European history between c. 1000 and c. 1300; it was preceded by the Early Middle Ages and followed by the Late Middle Ages, which ended c. 1500 according to historiographical convention. Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of the rural exodus and urbanization. By 1350, the robust population increase had greatly benefited the European economy, which had reached levels that would not be seen again in some areas until the 19th century. That trend faltered in the early 14th century, as the result of numerous events which together comprised the crisis of the late Middle Ages—most notable among them being the Black Death, in addition to various regional wars and economic stagnation.

From c. 780, Europe saw the last of the barbarian invasions and became more socially and politically organized. The Carolingian Renaissance stimulated scientific and philosophical activity in Northern Europe. The first universities started operating in Bologna, Oxford, Paris, Salamanca, Cambridge and Modena. The Vikings settled in the British Isles, France and elsewhere, and Norse Christian kingdoms started developing in their Scandinavian homelands. The Magyars ceased their expansion in the 10th century, and by 1000, a Christian Kingdom of Hungary had become a recognized state in Central Europe that was forming alliances with regional powers. With the brief exception of the Mongol invasions in the 13th century, major nomadic incursions ceased. The powerful Byzantine Empire of the Macedonian and Komnenos dynasties gradually gave way to the resurrected Serbia and Bulgaria and to a successor crusader state (1204 to 1261), who continually fought each other until the end of the Latin Empire. The Byzantine Empire was reestablished in 1261 with the recapture of Constantinople from the Latins, though it was no longer a major power and would continue to falter through the 14th century, with remnants lasting until the mid 15th century.

The Hungarian invasions of Europe (Hungarian: kalandozások, German: Ungarneinfälle) occurred in the 9th and 10th centuries, during the period of transition in the history of Europe of the Early Middle Ages, when the territory of the former Carolingian Empire was threatened by invasion by the Magyars (Hungarians) from the east, the Viking expansion from the north, and the Arabs from the south.

The Hungarians took possession of the Carpathian Basin (corresponding to the later Kingdom of Hungary) in a planned manner, with a long period of settlement between 862–895, and launched a number of campaigns both westward into former Francia and southward into the Byzantine Empire. The westward raids were stopped only with the Magyar defeat at the Battle of Lechfeld in 955, which led to the revival of the Holy Roman Empire in 962, producing a new political order in Western Europe. The raids into Byzantine territories continued throughout the 10th century, until the eventual Christianisation of the Magyars and the establishment of the Christian Kingdom of Hungary in 1000.

Slovenia, officially the Republic of Slovenia, is a country in Central Europe. Formed in 1991, Slovenia borders Italy to the west, Austria to the north, Hungary to the northeast, and Croatia to the south and southeast; its southwestern boundary consists of a 46.6 km coastline on the Adriatic Sea. Slovenia is mostly mountainous and forested, covers 20,271 square kilometres (7,827 sq mi), and has a population of approximately 2.1 million people. Slovene is the official language. Slovenia has a predominantly temperate continental climate, with the exception of the Slovene Littoral and the Julian Alps. Ljubljana, the capital and largest city of Slovenia, is geographically situated near the centre of the country. Other larger urban centers include Maribor, Ptuj, Kranj, Celje, and Koper.

Slovenia's territory has been part of many different states, including the Byzantine Empire, the Carolingian Empire, the Holy Roman Empire, the Kingdom of Hungary, the Republic of Venice, the Illyrian Provinces of Napoleon's First French Empire and the Habsburg Empire. The Kingdom of Serbs, Croats, and Slovenes was formed in December 1918; in 1929, the Kingdom became known as Yugoslavia. In 1946, after World War II, Slovenia was established as one of six republics that made up the socialist federation of Yugoslavia. In June 1991, Slovenia declared independence from Yugoslavia and became an independent sovereign state.

Hungary is a landlocked country in Central Europe. Spanning much 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 lies within the drainage basin of the Danube River and is dominated by great lowland plains. It has a population of 9.6 million, consisting mostly of ethnic Hungarians (Magyars) and a significant Romani minority. Hungarian is the official language, and among the few in Europe outside the Indo-European family. Budapest is the country's capital and largest city, and the dominant cultural and economic centre.

Prior to the foundation of the Hungarian state, various peoples settled in the territory of present-day Hungary, including the Celts, Romans, Huns, Germanic peoples, Avars and Slavs. Hungarian statehood is traced to the Principality of Hungary, which was established in the late ninth century by Álmos and his son Árpád through the conquest of the Carpathian Basin. King Stephen I ascended the throne in 1000 and converted his realm to a Christian kingdom. The medieval Kingdom of Hungary was a European power, reaching its height in the Late Middle Ages.

Slovakia, officially the Slovak Republic, is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the west, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about 49,000 km (19,000 sq mi), hosting a population exceeding 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice.

The Slavs arrived in the territory of the present-day Slovakia in the 5th and 6th centuries. From the late 6th century, parts of modern Slovakia were incorporated into the Avar Khaghanate. In the 7th century, the Slavs played a significant role in the creation of Samo's Empire. When the Avar Khaghanate dissolved in the 9th century, the Slavs established the Principality of Nitra before it was annexed by the Principality of Moravia, which later became Great Moravia. When Great Moravia fell in the 10th century, the territory was integrated into the Principality of Hungary at the end of the 9th century, which later became the Kingdom of Hungary in 1000. In 1241 and 1242, after the Mongol invasion of Europe, much of the territory was destroyed, but was recovered largely thanks to Hungarian king Béla IV. During the 16th and 17th centuries, southern portions of present-day Slovakia were incorporated into provinces of the Ottoman Empire. The Ottoman-controlled areas were ceded to the Habsburgs by the turn of the 18th century. The Hungarian declaration of independence in 1848 was followed in the same year by the Slovak Uprising through the establishment of the Slovak National Council. While the uprising did not achieve its aim, it played an important role in cementing a Slovak national identity. The Hungarian wars of independence eventually resulted in a compromise that established the Austro-Hungarian Empire.

Croatia, officially the Republic of Croatia, is a country in Central and Southeast Europe, on the coast of the Adriatic Sea. It borders Slovenia to the northwest, Hungary to the northeast, Serbia to the east, Bosnia and Herzegovina and Montenegro to the southeast, and shares a maritime border with Italy to the west. Its capital and largest city, Zagreb, forms one of the country's primary subdivisions, with twenty counties. Other major urban centers include Split, Rijeka and Osijek. The country spans 56,594 square kilometres (21,851 square miles), and has a population of nearly 3.9 million.

The Croats arrived in modern-day Croatia, then part of Roman Illyria, in the late 6th century. In the 7th century, they organized the territory into two duchies. Croatia was first internationally recognized as independent on 7 June 879 during the reign of Duke Branimir. Tomislav became the first king by 925, elevating Croatia to the status of a kingdom. During the succession crisis after the Trpimirović dynasty ended, Croatia entered a personal union with Hungary in 1102. In 1527, faced with Ottoman conquest, the Croatian Parliament elected Ferdinand I of Austria to the Croatian throne. In October 1918, the State of Slovenes, Croats, and Serbs, independent from the Habsburg Empire, was proclaimed in Zagreb, and in December 1918, it merged into the Kingdom of Yugoslavia. Following the Axis invasion of Yugoslavia in April 1941, most of Croatia was incorporated into a Nazi-installed puppet state, the Independent State of Croatia. A resistance movement led to the creation of the Socialist Republic of Croatia, which after the war became a founding member and constituent of the Socialist Federal Republic of Yugoslavia. On 25 June 1991, Croatia declared independence, and the War of Independence was successfully fought over the next four years.

The Capetian House of Anjou, or House of Anjou-Sicily was a royal house and cadet branch of the Capetian dynasty. It is one of three separate royal houses referred to as Angevin, meaning "from Anjou" in France. Founded by Charles I of Anjou, the youngest son of Louis VIII of France, the Capetian king first ruled the Kingdom of Sicily during the 13th century. The War of the Sicilian Vespers later forced him out of the island of Sicily, leaving him with the southern half of the Italian Peninsula, known as the Kingdom of Naples. The house and its various branches would go on to influence much of the history of Southern and Central Europe during the Middle Ages until it became extinct in 1435.

Historically, the house ruled the Counties of Anjou, Maine, Touraine, Provence and Forcalquier; the Principalities of Achaea and Taranto; and the Kingdoms of Sicily, Naples, Hungary, Croatia, Albania and Poland.
