Robert Carr was a favourite of James VI and I, he was created Earl of Somerset by the King and was lavished with a great many gifts and favours, however, he soon fell from favour and was replaced by George Villiers, who became Duke of Buckingham and a crucial advisor to both James and his son Charles. Robert Carr later sealed his complete doom with his involvement in the Overbury murder plot.
My query is this, what happens if Carr is not involved in Overbury's murder and therefore, is not imprisoned etc. He'd still have some small influence over James, but not a lot. Would he be able to compete with Buckingham for James's affections, or would he move onto the heir apparent, and try and ingratiate himself in with Charles? If he does so, how does this change Charles's early reign?
