Austrian Empire in the context of "London Conference of 1830"

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.

Moravia is a historical region in the east of the Czech Republic and one of three historical Czech lands, with Bohemia and Czech Silesia.

The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown from 1348 to 1918, an imperial state of the Holy Roman Empire from 1004 to 1806, a crown land of the Austrian Empire from 1804 to 1867, and a part of Austria-Hungary from 1867 to 1918. Moravia was one of the five lands of Czechoslovakia founded in 1918. In 1928 it was merged with Czech Silesia, and then dissolved in 1948 during the abolition of the land system following the communist coup d'état.

The Czech Republic, also known as Czechia and historically known as Bohemia, is a landlocked country in Central Europe. The country is bordered by Austria to the south, Germany to the west, Poland to the northeast, and Slovakia to the southeast. The Czech Republic has a hilly landscape that covers an area of 78,871 square kilometers (30,452 sq mi) with a mostly temperate continental and oceanic climate. The capital and largest city is Prague; other major cities and urban areas include Brno, Ostrava, Plzeň and Liberec.

The Duchy of Bohemia was founded in the late 9th century under Great Moravia. It was formally recognized as an Imperial Estate of the Holy Roman Empire in 1002 and became a kingdom in 1198. Following the Battle of Mohács in 1526, all of the Lands of the Bohemian Crown were gradually integrated into the Habsburg monarchy. Nearly a hundred years later, the Protestant Bohemian Revolt led to the Thirty Years' War. After the Battle of White Mountain, the Habsburgs consolidated their rule. With the dissolution of the Holy Roman Empire in 1806, the Crown lands became part of the Austrian Empire.

Milan (/mɪˈlæn/ mil-AN, US also /mɪˈlɑːn/ mil-AHN, Milanese: [miˈlãː] ; Italian: Milano [miˈlaːno] ) is the regional capital of Lombardy, in northern Italy, and the second-most populous city in Italy, with a population of 1.36 million in 2025. The Metropolitan City of Milan is the largest city in Italy by urban area. Its wider metropolitan area is the largest in Italy, and the fourth-largest in the European Union, with an estimated population of 6.1 million.

Founded around 590 BC by a Celtic tribe, Milan was conquered by the Romans in 222 BC, who Latinized the name of the city into Mediolanum and made it the capital of the Western Roman Empire. In the Late Medieval period, the wealthy Duchy of Milan was one of the greatest forces behind the Renaissance. As a major center of the Italian Enlightenment during the Early modern period, Milan's cultural and political struggle against Austrian domination was crucial in the reunification of the Kingdom of Italy. From the 19th century onwards, Milan led the industrial and financial development of Italy.

Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it.

Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. Following the German annexation of Austria in March 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in September 1939.

Veneto, officially the Region of Veneto, is one of the 20 regions of Italy, located in the north-east of the country. It is the 4th most populous region in Italy, with a population of 4,851,851 as of 2025. Venice is the region's capital while Verona is the largest city.

Veneto was part of the Roman Empire until the 5th century AD. Later, after a feudal period, it was part of the Republic of Venice until 1797. Venice ruled for centuries over one of the largest and richest maritime republics and trade empires in the world. After the Napoleonic Wars and the Congress of Vienna, the former Republic was combined with Lombardy and re-annexed to the Austrian Empire as the Kingdom of Lombardy–Venetia, until that was merged with the Kingdom of Italy in 1866, as a result of the Third Italian War of Independence and of a plebiscite.

Maximilian I (Spanish: Fernando Maximiliano José María de Habsburgo-Lorena; German: Ferdinand Maximilian Josef Maria von Habsburg-Lothringen; 6 July 1832 – 19 June 1867) was an Austrian archduke who became emperor of the Second Mexican Empire from 10 April 1864 until his execution by the Mexican Republic on 19 June 1867.

A member of the House of Habsburg-Lorraine, Maximilian was the younger brother of Emperor Franz Joseph I of Austria. Before becoming Emperor of Mexico, he was commander-in-chief of the small Imperial Austrian Navy and briefly the Austrian viceroy of Lombardy–Venetia, but was removed by the emperor. Two years before his dismissal, he briefly met with French emperor Napoleon III in Paris, where he was approached by conservative Mexican monarchists seeking a European royal to rule Mexico. Initially Maximilian was not interested, but following his dismissal as viceroy, the Mexican monarchists' plan was far more appealing to him.

The Concert of Europe was a general agreement between the great powers of 19th-century Europe to maintain the European balance of power, political boundaries, and spheres of influence. Never a perfect unity and subject to disputes and jockeying for position and influence, the Concert was an extended period of relative peace and stability in Europe following the Wars of the French Revolution and the Napoleonic Wars which had consumed the continent since the 1790s. There is considerable scholarly dispute over the exact nature and duration of the Concert. Some scholars argue that it fell apart nearly as soon as it began in the 1820s when the great powers disagreed over the handling of liberal revolts in Italy, while others argue that it lasted until the outbreak of World War I and others for points in between. For those arguing for a longer duration, there is generally agreement that the period after the Revolutions of 1848 and the Crimean War (1853–1856) represented a different phase with different dynamics than the earlier period.

The beginnings of the Concert System, known as the Congress System or the Vienna System after the Congress of Vienna (1814–1815), was dominated by the five great powers of Europe: Austria, France, Prussia, Russia, and the United Kingdom. Initially envisioning regular Congresses among the great powers to resolve potential disputes, in practice, Congresses were held on an ad hoc basis and were generally successful in preventing or localizing conflicts. The more conservative members of the Concert of Europe, members of the Holy Alliance (Russia, Austria, and Prussia), used the system to oppose revolutionary and liberal movements and weaken the forces of nationalism. The formal Congress System fell apart in the 1820s but peace between the Great Powers continued and occasional meetings reminiscent of the Congresses continued to be held at times of crisis.

The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon Bonaparte. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802) and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.

The first stage of the war broke out when Britain declared war on France on 18 May 1803. After some minor campaigns, Britain allied with Austria, Russia, and several minor powers to form the Third Coalition in April 1805. Napoleon defeated the allied Russo-Austrian armies in the subsequent war which climaxed in French victories at Ulm and at Austerlitz, leading to the dissolution of the Holy Roman Empire and Austria being forced to make peace by the end of the year. Britain and Russia remained at war with France. Concerned about increasing French power, Prussia joined Britain and Russia in the Fourth Coalition, which resumed war in October 1806. Napoleon defeated the Prussians at Jena-Auerstedt and the Russians at Friedland, bringing an uneasy peace to the continent by July 1807, and again leaving Britain as France's sole major enemy. Britain was unable to dispute French dominance on the continent but obtained hegemony over the seas after a string of victories including Trafalgar. Russia used the interim peace to resolve wars with the Ottomans, Swedes, and Iranians.

The House of Bonaparte (originally Buonaparte) is a former imperial and royal European dynasty of French and Italian origin. It was founded in 1804 by Napoleon I, the son of Corsican nobleman Carlo Buonaparte and Letizia Buonaparte (née Ramolino). Napoleon was a French military leader who rose to power during the French Revolution and who, in 1804, transformed the French First Republic into the First French Empire, five years after his coup d'état of November 1799 (18 Brumaire). Napoleon and the Grande Armée had to fight against every major European power (except for the ones he was allied with, including Denmark-Norway) and dominated continental Europe through a series of military victories during the Napoleonic Wars. He installed members of his family on the thrones of client states, expanding the power of the dynasty.

The House of Bonaparte formed the Imperial House of France during the French Empire, together with some non-Bonaparte family members. In addition to holding the title of Emperor of the French, the Bonaparte dynasty held various other titles and territories during the Napoleonic Wars, including the Kingdom of Italy, the Kingdom of the Spain and the Indies, the Kingdom of Westphalia, the Kingdom of Holland, and the Kingdom of Naples. The dynasty held power for around a decade until the Napoleonic Wars began to take their toll. Making very powerful enemies, such as Austria, Britain, Russia, and Prussia, as well as royalist (particularly Bourbon) restorational movements in France, Spain, the Two Sicilies, and Sardinia, the dynasty eventually collapsed due to the final defeat of Napoleon I at the Battle of Waterloo and the restoration of the Bourbon dynasty by the Congress of Vienna.
