Hey Guys,
Let's say that Elizabeth I of England, who IOTL died in 1603 and succeeded by James VI of Scotland, lives on another 25 years. I know that this is highly implausible, she was 69 when she died and so ITTL she would be 94 years old when death finally takes her. Obviously this doesn't mean she'll be healthy the whole time, and I assume for much of the end of her reign she'd be bed-ridden.
Whilst highly unlikely, IOTL
Christian Augustus, Count Palatine of Sulzbach lived to the old age of 85 in the 17th century, so this kind of age isn't totally unseen around this era.
So, what would happen? Obviously James VI would be annoyed as he'd be waiting for the death of Elizabeth, and if she might even live longer than him. How would it affect foreign affairs, especially with Spain?
Would we see the 'Republican' government grow even larger? IOTL the later reign saw her council and Parliament take on more responsibilities, but with an old and slowly deteriorating Elizabeth could we see Parliament and her Council grow in size and power?
Who would succeed her? If James' first son, Henry, survives due to butterflies I assume it'd be him, and he'd probably be a more effective ruler than IOTL's Charles I.
