What changes did the British Army have?

The history of the British Army spans over three and a half centuries since its founding in 1660 and involves numerous European wars, colonial wars and world wars. From the late 17th century until the mid-20th century, the United Kingdom was the greatest economic and imperial power in the world, and although this dominance was principally achieved through the strength of the Royal Navy (RN), the British Army played a significant role.

As of 2015, there were 92,000 professionals in the regular army (including 2,700 Gurkhas) and 20,480 Volunteer Reserves.[1] Britain has generally maintained only a small regular army during peacetime, expanding this as required in time of war, due to Britain's traditional role as a sea power. Since the suppression of Jacobitism in 1745, the British Army has played little role in British domestic politics (except for the Curragh incident), and, apart from Ireland, has seldom been deployed against internal threats to authority (one notorious exception being the Peterloo Massacre).The British Army has been involved in many international conflicts, including the Napoleonic Wars, the Crimean War and both World War I and World War II. Historically, it contributed to the expansion and retention of the British Empire.

The British Army has long been at the forefront of new military developments. It was the first in the world to develop and deploy the tank, and what is now the Royal Air Force (RAF) had its origins within the British Army as the Royal Flying Corps (RFC). At the same time the British Army emphasises the continuity and longevity of several of its institutions and military tradition.
