Napoleonic Wars in the context of "British Century"

A unitary state is a sovereign state governed as a single entity in which the central government is the supreme authority. The central government may create or abolish administrative divisions (sub-national or sub-state units). Such units exercise only the powers that the central government chooses to delegate. Although political power may be delegated through devolution to regional or local governments by statute, the central government may alter the statute, to override the decisions of devolved governments or expand their powers.

The modern unitary state concept originated in France; in the aftermath of the Hundred Years' War, national feelings that emerged from the war unified France. The war accelerated the process of transforming France from a feudal monarchy to a unitary state. The French then later spread unitary states by conquests, throughout Europe during and after the Napoleonic Wars, and to the world through the vast French colonial empire. Presently, prefects remain an illustration of the French unitary state system, as the representatives of the State in each department, tasked with upholding central government policies.

Gibraltar (/dʒɪˈbrɔːltər/ jih-BRAWL-tər, Spanish: [xiβɾalˈtaɾ]) is a British Overseas Territory and city located at the southern tip of the Iberian Peninsula, on the Bay of Gibraltar, near the exit of the Mediterranean Sea into the Atlantic Ocean (Strait of Gibraltar). It has an area of 6.8 km (2.6 sq mi) and is bordered to the north by Spain (Campo de Gibraltar). The landscape is dominated by the Rock of Gibraltar, at the foot of which is a densely populated town area. Gibraltar is home to around 34,000 people, primarily Gibraltarians.

Gibraltar was founded as a permanent watchtower by the Almohads in 1160. It switched control between the Nasrids, Castilians and Marinids in the Late Middle Ages, acquiring larger strategic clout upon the destruction of nearby Algeciras c. 1375. It became again part of the Crown of Castile in 1462. In 1704, Anglo-Dutch forces captured Gibraltar from Spain during the War of the Spanish Succession, and it was ceded to Great Britain in perpetuity under the Treaty of Utrecht in 1713. It became an important base for the Royal Navy, particularly during the Napoleonic Wars and World War II, as it controlled the narrow entrance and exit to the Mediterranean Sea, the Strait of Gibraltar, with half the world's seaborne trade passing through it.

Germany, officially the Federal Republic of Germany, is a country in Western and Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen constituent states have a total population of over 83 million, making it the most populous member state of the European Union. Germany borders Denmark to the north; Poland and the Czech Republic to the east; Austria and Switzerland to the south; and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr.

Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts, with Germanic tribes inhabiting the north. Romans named the area Germania. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation. Following the Napoleonic Wars and the dissolution of the Holy Roman Empire in 1806, the German Confederation was formed in 1815.

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.

The Peninsular War (1808–1814) was fought in the Iberian Peninsula by the Iberian nations Spain and Portugal, and the United Kingdom against the invading and occupying forces of the First French Empire during the Napoleonic Wars. In Spain, it is considered to overlap with the Spanish War of Independence. It overlapped with the War of the Fifth Coalition (1809) and the War of the Sixth Coalition (1812-1814).

The war can be said to have started when the French and Spanish armies invaded and occupied Portugal in 1807 by transiting through Spain, but it escalated in 1808 after Napoleonic France occupied Spain, which had been its ally. Napoleon Bonaparte forced the abdications of Ferdinand VII and his father Charles IV and then installed his brother Joseph Bonaparte on the Spanish throne and promulgated the Bayonne Constitution. Most Spaniards rejected French rule and fought a bloody war to oust them. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and is regarded as one of the first wars of national liberation. It is also significant for the emergence of large-scale guerrilla warfare.

Academic art, academicism, or academism, is a style of painting and sculpture produced under the influence of European academies of art. This method extended its influence throughout the Western world over several centuries, from its origins in Italy in the mid-16th century, until its dissipation in the early 20th century. It reached its apogee in the 19th century, after the end of the Napoleonic Wars in 1815. In this period, the standards of the French Académie des Beaux-Arts were very influential, combining elements of Neoclassicism and Romanticism, with Jean-Auguste-Dominique Ingres a key figure in the formation of the style in painting. The success of the French model led to the founding of countless other art academies in several countries. Later painters who tried to continue the synthesis included William-Adolphe Bouguereau, Thomas Couture, and Hans Makart among many others. In sculpture, academic art is characterized by a tendency towards monumentality, as in the works of Auguste Bartholdi and Daniel Chester French.

The academies were established to replace medieval artists' guilds and aimed to systematize the teaching of art. They emphasized the emulation of established masters and the classical tradition, downplaying the importance of individual creativity, valuing instead collective, aesthetic and ethical concepts. By helping raise the professional status of artists, the academies distanced them from artisans and brought them closer to intellectuals. They also played a crucial role in organizing the art world, controlling cultural ideology, taste, criticism, the art market, as well as the exhibition and dissemination of art. They wielded significant influence due to their association with state power, often acting as conduits for the dissemination of artistic, political, and social ideals, by deciding what was considered "official art". As a result, they faced criticism and controversy from artists and others on the margins of these academic circles, and their restrictive and universalist regulations are sometimes considered a reflection of absolutism.

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.

Decolonization is the undoing of colonialism, the latter being the process whereby imperial nations establish and dominate foreign territories, often overseas. The meanings and applications of the term are disputed. Some scholars of decolonization focus especially on independence movements in the colonies and the collapse of global colonial empires.

As a movement to establish independence for colonized territories from their respective metropoles, decolonization began in 1775 with the American Revolution in North America against the British Empire. The Napoleonic Wars in the 19th century saw the French colonial empire, the Spanish Empire, and Portugal face decolonization with the Haitian Revolution, the Spanish American wars of independence, and the independence of Brazil from Portugal. A major wave of decolonization occurred in the aftermath of the First World War, including in the United States and the Empire of Japan. Another wave of decolonization occurred after the Second World War, and many countries gained their independence in the following years. The last wave of decolonization occurred after the Cold War with the collapse of the Soviet Union, the independence of Palau, and the handovers of Hong Kong and Macau. Seventeen territories remain under the United Nations classification of non-self-governing territories.

A great power is a nation, state or empire that, through its economic, political and military strength, is able to exert power and influence not only over its own region of the world, but beyond to others. A great power typically possesses military, economic, and diplomatic strength that it can wield to influence the actions of middle or small powers.

In a modern context, recognized great powers first arose in Europe during the post-Napoleonic era. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814.
