Henry Stuart, Duke of Gloucester (8 July 164013 September 1660) was the youngest son of Charles I, King of England, Scotland, and Ireland, and his wife, Henrietta Maria of France. He is also known as Henry of Oatlands. From the age of two, Henry, along with his sister Elizabeth, were separated from their family during the English Civil War and became prisoners of Parliament. For several years, the children were constantly transported from one residence to another due to the plague raging in London. They also periodically changed their governesses and guardians to those more loyal to the government.

Before leaving for Carisbrooke, Henry and Elizabeth were stripped of all titles and privileges. Shortly after arriving on the Isle of Wight in September 1650, Henry's sister fell ill and died. Henry remained at Carisbrooke until the following year, when, with the permission of Oliver Cromwell, he returned to the continent, where he eventually joined his mother in Paris. With Henrietta Maria, whom the prince had not seen for eleven years, Henry did not have a good understanding: the prince was an ardent Protestant, and his mother was an implacable Catholic. The Queen, against the wishes of her late husband and eldest son, tried to convert Henry to Catholicism, but this only deteriorated their relationship. Henry went to his brother Charles in Cologne. In 1657, the prince fought on the side of the
