The Union flag - Union Jack
The flag of the United Kingdom of Great Britain and Northern Ireland is a combination of more flags.
It is known as "Union Jack" although it is often stated that the Union Flag should only be described as the "Union Jack" when flown in the bows of a warship.
There is also the theory that the name "Union Jack" came from King James, whose name is "Jacobus" in Latin, and "Jacob" in Hebrew.
