Wars and Conflicts of England and Great Britain

British Soldiers in Afghanistan

Great Britain is really only a part of the United Kingdom of Great Britain and Northern Ireland, but it is of course, the largest part. Great Britain itself is an island off the northwest coast of Europe and is comprised of three countries united into one kingdom. Those three countries are: England, Scotland, and Wales.

For many centuries, these three nations, along with Ireland, waged war against each other. Eventually, the English defeated the Scots and the Welsh (and the Irish), and a series of Acts of Union were passed that eventually resulted in what would later be known as the United Kingdom. In 1535, England and Wales were united as one kingdom, and in 1707, the Act of Union brought Scotland into the Kingdom of Great Britain.

This page presents a listing, with some details, of many of the wars of Great Britain (including separate English and Scottish wars) from early history to the present.

The Boxer Rebellion (1899-1900)-- The Chinese secret religious and nationalistic Society of the Righteous Harmonious Fists (Boxers), initiated a rebellion against both foreign colonizers, missionaries and their own government in 1899. By 1900, the Chinese government had co-opted the rebels and directed their violent fury entirely upon the foreign presence in China. The Boxers, aided by Chinese Imperial troops, besieged the diplomatic legations (embassies) of the Western powers and Japan, sparking a truly international response.

Since the ending of the British Mandate and the advent of full Iraqi independence in 1932, Britain retained a great deal of military influence in Iraq, despite lingering opposition from many Arab nationalists. One of these nationalists, Rashid Ali, seized power in Baghdad and refused British requests to allow British military forces to enter Iraq. Britain at this time was fighting German and Italian forces in North Africa and were preparing to invade Vichy French-held Syria. (The Vichy French were working with the Germans and British and Free French forces needed to secure the region). Believing promises of German support, Rashid Ali ordered his forces to attack British bases in western Iraq and to oppose the landing of British forces at the southern city of Basra. German support appeared in the form of a small number of Luftwaffe fighter planes, and the British forces quickly defeated the Iraqi military.

Cold War (1945-1990)--Britain, along with the United States and other Western nations, formed the backbone of anti-Communist resistance in the Cold War.

Greek Civil War (1944-1947)--British forces became involved in the early stages of the Greek Civil War when they liberated Greece from German occupation toward the end of 1944. As the Germans withdrew, competing Greek factions fought for control. The British sided with the re-established Greek government against the Communist rebels. Due to financial pressures and their own need to recover from World War Two, Britain announced a withdrawal of forces in 1947. The Greek Civil War continued until 1949, with the United States taking over the role of protector for the government. British combat involvement primarily took place in 1944 and 1945. The Greek Civil War continued until the Greek government defeated the rebels in 1949.

The conflict ended with a change in the Egyptian government and the eventual withdrawal of British troops. This conflict led to Britain's involvment in the 1956 Anglo-French-Israeli invasion of Egypt in 1956. (see below)
