The size and power of the Royal Navy internationally at the time could also explain why the flag was named the "Union Jack"; considering the navy was so widely utilised and renowned by the United Kingdom and colonies, it is possible that the term "jack" occurred because of its regular use on all British ships using the jackstaff (a flag pole attached to the bow of a ship). The term "Union Jack" possibly dates from Queen Anne's time (r. 1702–14), but its origin is uncertain. It may come from the 'jack-et' of the English or Scottish soldiers, or from the name of James I who originated the first union in 1603. Even if the term "Union Jack" does derive from the jack flag, after three centuries, it is now sanctioned by use and has appeared in official use, confirmed as the national flag by Parliament and remains the popular term.
