A movement subsequently rose demanding that the King was removed as the head of the Church of England.

[Uncanny]

I am wondering how the Subjunctive Mood functions in the past, considering this sentence:

A movement subsequently rose demanding that the King was removed as the head of the Church of England.

My question is, why not:

A movement subsequently rose demanding that the King be removed as the head of the Church of England.
A movement subsequently rose demanding that the King should be removed as the head of the Church of England.

I prefer your first option to the original.

Remember that most native speakers will have had limited formal instruction in English grammar. I learned, and have since forgotten, far more from studying French and Latin between the ages of 12 and 16. For the average person it's a matter of what "sounds right" and sometimes we make mistakes.
