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 Jack. The ensign originated in the 17th century with the St George's cross (the Flag of England) in the canton, and with a blue field (top right).
The Acts of Union 1707 united England and Wales with Scotland in the Kingdom of Great Britain, thus producing a new Blue Ensign with the new Union Flag in the canton. With the Act of Union 1800, Ireland joined the United Kingdom and St Patrick's Cross was added to the Union Flag and, accordingly, to the cantons of all 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.
- British merchant vessels whose officers and crew include a certain number of retired Royal Navy personnel or Royal Navy reservists, or are commanded by an officer of the Royal Naval Reserve in possession of a Government warrant. The number and rank of such crew members required has varied over the years, as have the additional conditions required, since the system was first introduced in 1864.
