It is the national flag of the United Kingdom
of Great Britain and Northern Ireland - it also
retains use in some Commonwealth Realms
And whether to use Union Flag or Union Jack
is a question of debate.
From early in its life, the Lord High Admiralty
referred to the flag as Union Jack, since they
ruled the waves; and should be regarded as
the national flag - and after three centuries
it was never called the Union Flag.
Various shades of blue (my favorite color)
have been used in the Saltire over the years
To the south, they use a navy blue; to the
north, it's royal blue; the blazon is Azure
For its color from the old flag is the current's.
It is represented by the flag of St. George
who is the patron saint of England; Scotland
is represented by the flag of St. Andrew - a
compromise was reached in 1606 and it led
to the creation of the first Union Jack.
But not before Northern Ireland's St. Patrick
was added - to make a long story short, the
formation of the Union Jack came about as
the result of the progressive merging of the
inhabitants of the British Isles - Rule Britannia!
