Why is Wales not represented in the Union Jack?

Wales is actually represented in the Union Jack. The Union Jack is made up of the flags of England and Scotland, and the Union Flag (also known as the Union Jack). The Union Flag is made up of the flags of England, Scotland, and Northern Ireland. The Welsh flag is not included in the Union Jack because Wales was not a separate kingdom when the flag was created. Wales was annexed by England in the 13th century, and it has been part of the United Kingdom since 1707.
