Who is Queen Elizabeth II Scotland?

Answer

Scotland is part of the United Kingdom of Great Britain and Northern Ireland, so Her Majesty Queen Elizabeth II, the current monarch is in effect Queen of Scotland although that title does not formally exist.

In actual fact, Queen Elizabeth II is only Queen Elizabeth II in England. As Scotland had never previously had a Queen Elizabeth, Queen Elizabeth II is actually only Queen Elizabeth I in Scotland. (The previous Queen Elizabeth in England was not a monarch in Scotland as the Union of the Crowns occurred on her death with James VI of Scotland becoming King in England (in England he was known as James I)).

There are some factual errors here.

James I of England was James VI of Scots (note Scots not Scotland in the title)

This was because there were two distinct kingdoms he reigned over.

The two kingdoms were united into Great Britain in 1707 (later becoming the United Kingdom in 1801 when Ireland was added in)

Since that time Monarchs take the highest ordinal number that has existed in either England (from 1066) or Scotland.

There have been 3 Richards in England and none in Scotland. If there was another King Richard he would be Richard IV of the UK

Similalry there have been 3 Roberts in Scotland and none in England. If there was another King Robert he would be Robert IV of the UK

Hence the current Queen is Elizabeth II in both countries.

There may be some Scottish nationist who would take issue with this but desiring on thing is different to how it actually is and besides, they could still be independent with the same Queen as in Austraila or Canada she is afterall probably more Scottish than English and overall more German one could argue.
