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, [1] to the present day.
From the 18th century onwards, with the expansion of the British Empire and the country's industrial strength, the British military became one of the most powerful and technologically advanced militaries in Europe and the world. Its navy in particular, with major bases in four Imperial fortresses and coaling stations surrounding the globe, was the world's greatest naval force from the 18th to the mid-20th century. British military declined in the mid-20th century as did those of the traditional European continental powers following the two world wars, decolonisation, and the rise of the United States and the Soviet Union as the new superpowers. However, Britain remains a major military power with frequent military interventions around the world since the end of the Cold War in 1991. The present-day British Armed Forces encompass the Royal Navy, the British Army, and the Royal Air Force.
Britain has been involved in a great many armed conflicts since the union in 1707, on all continents except for Antarctica.
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. 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.
The Maratha Empire, also referred to as the Maratha Confederacy, was an early modern Indian empire and later a confederation that controlled large portions of the Indian subcontinent in the 18th century. Maratha rule formally began in 1674 with the coronation of Shivaji of the Bhonsle dynasty as the Chhatrapati. Although Shivaji came from the Maratha caste, the Maratha empire also included warriors, administrators, and other nobles from the Maratha and several other castes from what is known today as Maharashtra. The Maratha Kingdom was expanded into a full-fledged Empire in the 18th Century CE under the leadership of Peshwa Bajirao I.
Colonial India was the part of the Indian subcontinent that was occupied by European colonial powers during the Age of Discovery. European power was exerted both by conquest and trade, especially in spices. The search for the wealth and prosperity of India led to the colonisation of the Americas after Christopher Columbus went to the Americas in 1492. Only a few years later, near the end of the 15th century, Portuguese sailor Vasco da Gama became the first European to re-establish direct trade links with India by being the first to arrive by circumnavigating Africa. Having arrived in Calicut, which by then was one of the major trading ports of the eastern world, he obtained permission to trade in the city from the Saamoothiri Rajah. The next to arrive were the Dutch, with their main base in Ceylon. Their expansion into India was halted after their defeat in the Battle of Colachel to the Kingdom of Travancore, during the Travancore–Dutch War.
The Anglo-Mysore Wars were a series of four wars fought during the last three decades of the 18th century between the Sultanate of Mysore on the one hand, and the British East India Company, Maratha Empire, Kingdom of Travancore, and the Kingdom of Hyderabad on the other. Hyder Ali and his succeeding son Tipu fought the wars on four fronts: with the British attacking from the west, south and east and the Nizam's forces attacking from the north. The fourth war resulted in the overthrow of the house of Hyder Ali and Tipu, and the dismantlement of Mysore to the benefit of the East India Company, which took control of much of the Indian subcontinent.
The provinces of India, earlier presidencies of British India and still earlier, presidency towns, were the administrative divisions of British governance on the Indian subcontinent. Collectively, they have been called British India. In one form or another, they existed between 1612 and 1947, conventionally divided into three historical periods:
A subsidiary alliance, in South Asian history, was a tributary alliance between an Indian state and a European East India Company.
The Maratha Conquests were a series of conquests in the Indian subcontinent which led to the building of the Maratha Empire. These conquests were started by Shivaji in 1659, from the victory at the Battle of Pratapgad against Bijapur. The expansion of the empire was limited and interrupted by the Mughal conquests of south India by Mughal ruler Aurangzeb until he eventually died in 1707 in Deccan itself. Marathas were forced to defend their territories against the overwhelmingly strong Mughal army in the 27 years long Deccan wars. They were able to defend their territories and gain an upper hand over Mughals in the sustained conflict.
The Second Hundred Years' War is a periodization or historical era term used by some historians to describe the series of military conflicts around the globe between Great Britain and France that occurred from about 1689 to 1815, including several separate wars such as the War of the Spanish Succession, War of the Austrian Succession, French and Indian War, American Revolutionary War and the Napoleonic Wars. The Second Hundred Years' War is named after the Hundred Years' War, which occurred in the 14th and 15th century. The term appears to have been coined by J. R. Seeley in his influential work The Expansion of England (1883).

The presidency armies were the armies of the three presidencies of the East India Company's rule in India, later the forces of the British Crown in India, composed primarily of Indian sepoys. The presidency armies were named after the presidencies: the Bengal Army, the Madras Army and the Bombay Army. Initially, only Europeans served as commissioned or non-commissioned officers. In time, Indian Army units were garrisoned from Peshawar in the north, to Sind in the west, and to Rangoon in the east. The army was engaged in the wars to extend British control in India and beyond.
The Maratha–Mysore Wars were a conflict in 18th century India between the Maratha Empire and the Kingdom of Mysore. Though initial hostilities between the sides started in 1770s, the last battle began on February 1785 and ended in 1787.
The British Militia was the principal military reserve force of the Kingdom of Great Britain. Militia units were repeatedly raised in Great Britain during the Georgian era for internal security duties and to defend against external invasions. The Militia Act 1757, passed by the Parliament of Great Britain after the outbreak of the Seven Years' War, led to the rapid expansion of the British Militia in order to defend from potential French invasions. In the Kingdom of Ireland, a client state of Great Britain, the equivalent force was the Irish Militia, which saw heavy service in the Irish Rebellion of 1798 alongside British militia units. The existence of militia units in Great Britain and Ireland played an important role in freeing regular troops from the British and Irish establishments for overseas service.
