The Union Flag, or Union Jack, is the national flag of the United Kingdom. It is so called because it combines the crosses of the three countries united under one Sovereign - the kingdoms of England and Wales, of Scotland and of Ireland (although since 1921 only Northern Ireland has been part of the United Kingdom).
