Hello and welcome. f prince harry was to marry Markle and become king, the actress would not be queen , let me explain why. Prince Harry is NOT “second in line” to the throne Not even close. He’s actually fifth, behind his father Prince Charles, his brother Prince William, his nephew Prince George and his niece Princess Charlotte. Barring a massive tragedy, it is almost certain that Prince Harry will never ascend to the throne. That’s why he’s nicknamed the “spare heir. And that’s also why there’s a slim to zero chance Markle would ever end up ruling the royal family, should she actually wed Prince Harry. Furthermore, even if the two do tie the knot, and even if Prince Harry ends up one day becoming king, Markle still wouldn’t be the “first black queen.” She would be a consort to the king, and given a specific title such as “queen consort” or princess consort.” Queen Elizabeth’s husband, like Markle, is a foreigner, and he is not known as “king,” but as the “prince consort” and “Duke of Edinburgh.” And even if he were to marry Markle and become king, the actress would not be queen in any way Many Thanks for watching.
