Prince Harry is going where other British royals haven’t for over a century: to a courtroom witness stand. The Duke of Sussex is set to testify in the first of his five pending legal cases largely centered around battles with British tabloids. Opening statements are scheduled Monday in his case.

If Harry testifies as scheduled Tuesday in his lawsuit against the publisher of the Daily Mirror, he’ll be the first member of the royal family to do so since the late 19th century, when Queen Victoria’s eldest son, Prince Albert Edward, testified twice in court.
