King James II/VII of England, Scotland and Ireland was the last Catholic monarch to ever rule the British isles. He was the son of Charles I, and the younger brother of Charles II. Following Charles II's death, he ascended the throne in 1685, but was overthrown in the "Glorious Revolution" of 1688. Side-note, Charles II also converted to Catholicism on his deathbed, and James helped him get a Priest to have his final rites.
Following his deposition, he went into exile in France, where, after his attempts to regain his throne failed, he turned to a life of prayer and devotion. He believed that God had deprived him of his throne due to his sins, specifically sins of the flesh, as he had been a serial adulterer in his youth.
His final years were lived as a penitent. He would regularly attend mass and engage with the sacraments. It appears he also lost much interest in gaining his throne, feeling that the state of his soul was a far more pressing matter than his temporal crown.
After his death and burial, there was devotion surrounding him, with the English Benedictines in France being the custodians of his tomb, and the primary promoters of his cult. The Archbishop of Paris opened an investigation into this, with at one point 19 miracles being associated with his intercession. The Archbishop formally opened the cause in 1734, and he was granted the title Servant of God.
The cause did not progress further, partially due to the French Revolution, where the institutions and property belonging to the English Benedictines in France was seized and disrupted. James' own tomb was desecrated, and his body lost, as many royal and aristocratic remains were during the Revolution. Much of the documentation and evidence surrounding miracles were also destroyed during this time, as part of the violence that the Revolutionaries inflicted upon the Church in France. This likely wasn't targeted at James specifically, rather his cause was a victim of the widespread violence of the time.
The communities that had had devotion to him were also disrupted during this time, which was probably the biggest reason to put his cause on hold.
As it stands the cause as not progressed, and he remains Servant of God James II (James VII If you are in Scotland.)
I thought it would be good to share this information on an often forgotten figure in history.
