The 18th century lasted from 1 January 1701 (represented by the Roman numerals MDCCI) to 31 December 1800 (MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the Atlantic Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. 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. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events. To historians who expand the century to include larger historical movements, the "long" 18th century may run from the Glorious Revolution of 1688 to the Battle of Waterloo in 1815 or even later.In Europe, philosophers ushered in the Age of Enlightenment. This period coincided with the French Revolution of 1789, and was later compromised by the excesses of the Reign of Terror. At first, many monarchies of Europe embraced Enlightenment ideals, but in the wake of the French Revolution they feared loss of power and formed broad coalitions to oppose the French Republic in the French Revolutionary Wars. Various conflicts throughout the century, including the War of the Spanish Succession and the Seven Years' War, saw the Kingdom of Great Britain triumph over its European rivals to become the preeminent power in Europe. However, Britain's attempts to exert its authority over its colonies became a catalyst for the American Revolution. The 18th century also marked the end of the Polish–Lithuanian Commonwealth as an independent state. Its semi-democratic government system was not robust enough to rival the neighboring states of Prussia, Russia, and Austria, which partitioned the Polish–Lithuanian Commonwealth between themselves, changing the landscape of Central Europe and politics for the next hundred years. In Africa, the Ethiopian Empire underwent the Zemene Mesafint, a period when the country was ruled by a class of regional noblemen and the emperor was merely a figurehead. The Atlantic slave trade also encouraged the formation of states such as the Bamana Empire. The Ottoman Empire experienced an unprecedented period of peace and economic expansion, taking no part in European wars from 1740 to 1768. As a result, the empire was not exposed to Europe's military improvements during the Seven Years' War. The Ottoman military consequently lagged behind and suffered several defeats against Russia in the second half of the century. In West Asia, Nader Shah led successful military campaigns, which indirectly led to the founding of the Durrani Empire. In South Asia, the death of Mughal emperor Aurangzeb marked the end of medieval India and the beginning of an increasing level of European influence and control in the region, this period also with an episode of rapid Maratha expansion. In 1739, Persian emperor Nader Shah invaded and plundered Delhi, the capital of the Mughal Empire. Later, his general Ahmad Shah Abdali scored another defeat against the Marathas, the then dominant power in India, in the Third Battle of Panipat in 1761. By the middle of the century, the British East India Company began to conquer eastern India, and by the end of the century, the Anglo-Mysore Wars against Tipu Sultan and his father Hyder Ali, led to Company rule over the south.In East Asia, the century marked the High Qing era and the continual seclusion policies of the Tokugawa shogunate. European colonization intensified in present-day Indonesia, where the Dutch East India Company established increasing levels of control over the Mataram Sultanate. Southeast Asia would experience the major upheavals of the Konbaung–Ayutthaya Wars and the Tây Sơn rebellion. In Oceania, the European colonization of Australia and New Zealand began during the late half of the century. Source: Wikipedia (en)
