The last British Royal arrested prior to Andrew Windsor-Mountbatten was King Charles I, who faced significant legal consequences in the 17th century. Charles I was tried and executed for treason in 1649, marking a historical event that set a precedent for royal accountability.

The last arrest of a senior member of the royal family before Andrew was King Charles I in 1649.

Charles I was charged with treason. Andrew's current charges are the watered down form: misconduct in public office related to his connections with Jeffrey Epstein (he gave the pedophile blackmailer insider information).

Andrew's arrest on February 19, 2026, is notable as it is the first time a senior royal has been arrested in modern history, emphasizing a shift in the legal landscape concerning royal accountability.

The historical context highlights the rarity and gravity of such events within the British monarchy, making Andrew's situation unprecedented in recent centuries.
