There is much discussion regarding the name "Union Jack." In maritime history, a "jack" was a small flag flown from a jackstaff at the bow of a ship. These small flags were used as signals or to identify a vessel's nationality. Because the Union Flag was frequently flown as a small jack on naval ships, the name "Union Jack" became very common. Some historical sources, like the Admiralty in 1913, tried to insist that "Union Flag" was the correct term for the national flag. However, other authoritative sources, such as the 1909 book by Arthur Charles Fox-Davies, used "Union Jack" freely. Today, the Flag Institute states that both names are acceptable for the national flag.
