United Kingdom

The United Kingdom of Great Britain and Northern Ireland is a sovereign state located off the north-western coast of continental Europe. The country includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border the UK is surrounded by the Atlantic Ocean, the North Sea , the English Channel and the Irish Sea.

It is ruled by Queen Elizard.

Background
The Kingdom of Great Britain, described occasionally as the United Kingdom of Great Britain, was a sovereign state in northwest Europe , that existed from 1707 to 1801. On 1 January 1801, the Kingdom of Great Britain and the Kingdom of Ireland united to form the United Kingdom of Great Britain and Ireland. Most of Ireland left the union as the Irish Free State in 1922, leading to the remaining state being renamed as the United Kingdom of Great Britain and Northern Ireland in 1927.

It is unknown on how the United Kingdom of Great Britain and Northern Ireland exactly came to be in the Toaru Majutsu no Index universe, though it can be assumed that its formation is similar to that of the real world.

The state uses the Union Jack as its flag.

World War III
The United States of America, allied with the United Kingdom of Great Britain and Northern Ireland, and part of the science-side, takes part in the War, but their contributions are largely overshadowed during the event, due to to Academy City's overwhelming technological superiority.
