What it means

Where it came from

The Union Jack is three flags in one. In 1606 King James, who ruled both England and Scotland, combined the red cross of Saint George (England) with the white diagonal cross of Saint Andrew (Scotland) on blue.

When Great Britain and Ireland united on 1 January 1801, the red diagonal cross of Saint Patrick (Ireland) was added. The red and white diagonals were offset so Scotland's white cross keeps the place of honour near the flagpole at the top.

History

At first the 1606 flag was used mainly at sea, and in 1634 it was limited to Royal Navy ships. It became the national flag after England and Scotland united in 1707.

When most of Ireland left the United Kingdom in 1922, the flag did not change, because Northern Ireland stayed. Wales is not shown, because it was already part of the Kingdom of England in 1606. No law makes it the national flag; it is the national flag by long custom.
