Blue Ensign

The Blue Ensign is a flag, one of several British ensigns, used by certain organisations or territories associated with the United Kingdom. It is used either plain, or defaced with a badge or other emblem.

The evolution of the Blue Ensign followed that of the Union Flag. The ensign originated in the 17th century with the St George's cross (see Flag of England) in the canton, and with a blue field background (top right).

The Acts of Union 1707 united Scotland, England and Wales in the Kingdom of Great Britain and produced a new blue ensign which placed the Union Flag in the canton. With the Act of Union 1800, Ireland joined the United Kingdom and the St Patrick's Cross was added to the Union Flag of the United Kingdom and, accordingly, to the cantons of the British ensigns from 1 January 1801.

Plain blue ensign

Prior to the reorganisation of the Royal Navy in 1864, the plain blue ensign had been the ensign of one of three squadrons of the Royal Navy, the Blue Squadron. This changed in 1864, when an order in council provided that the Red Ensign was allocated to merchantmen, the Blue Ensign was to be the flag of ships in public service or commanded by an officer in the Royal Naval Reserve, and the White Ensign was allocated to the Navy.

Thus, after 1864, the plain blue ensign is permitted to be worn, instead of the Red Ensign, by two categories of civilian vessel:

Defaced blue ensign

Since 1864, the Blue Ensign is defaced with a badge or emblem, to form the ensign of United Kingdom government departments or public bodies, for example:-
