Prince Harry and Meghan Markle have been happily married for over six years, but there was one hurdle they had to clear first. Before popping the question to Meghan, Harry had to seek permission from his late grandmother due to a longstanding royal tradition.The rule states that the first six individuals in line to the throne must obtain the monarch's approval before getting engaged. When Harry knew he was ready to take the next step with Meghan, he approached the late Queen for her blessing before offering the former actress her engagement ring.
