The history of Europe is traditionally divided into four time periods: prehistoric Europe, classical antiquity, the Middle Ages, and the modern era.
The 18th century lasted from 1 January 1701 to 31 December 1800 (MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the Atlantic Revolutions. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. The European colonization of the Americas and other parts of the world intensified and associated mass migrations of people grew in size as part of the Age of Sail. During the century, slave trading expanded across the shores of the Atlantic Ocean, while declining in Russia and China.
The Napoleonic Wars (1803–1815) were a series of conflicts fought between the First French Empire under Napoleon Bonaparte (1804–1815) and a fluctuating array of European coalitions. 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 War of the Second Coalition was the second war targeting revolutionary France by many European monarchies, led by Britain, Austria, and Russia and including the Ottoman Empire, Portugal, Naples and various German monarchies. Prussia did not join the coalition, while Spain supported France.
A series of military conflicts between the Ottoman Empire and various European states took place from the Late Middle Ages up through the early 20th century. The earliest conflicts began during the Byzantine–Ottoman wars, waged in Anatolia in the late 13th century before entering Europe in the mid-14th century with the Bulgarian–Ottoman wars. The mid-15th century saw the Serbian–Ottoman wars and the Albanian-Ottoman wars. Much of this period was characterized by the Ottoman expansion into the Balkans. The Ottoman Empire made further inroads into Central Europe in the 15th and 16th centuries, culminating in the peak of Ottoman territorial claims in Europe.
The military history of Portugal is as long as the history of the country, from before the emergence of the independent Portuguese state.
The military history of Spain, from the period of the Carthaginian conquests over the Phoenicians to the former Afghan War spans a period of more than 2200 years, and includes the history of battles fought in the territory of modern Spain, as well as her former and current overseas possessions and territories, and the military history of the people of Spain, regardless of geography.
The military history of the United Kingdom covers the period from the creation of the united Kingdom of Great Britain, with the political union of England and Scotland in 1707, to the present day.
The European balance of power is a tenet in international relations that no single power should be allowed to achieve hegemony over a substantial part of Europe. During much of the Modern Age, the balance was achieved by having a small number of ever-changing alliances contending for power, which culminated in the World Wars of the early 20th century.
