Queen Elizabeth was without a doubt one of the most popular people in the world, while also being significantly less controversial than any politicians or celebrities of the same scale. However this raises the question... what actions did Queen Elizabeth take that made her so popular? As monarch she had almost zero decision power and never spoke on politically sensitive matters, so clearly "good policy making" cannot be the answer.
An ideal answer would include references to surveys asking British citizens why they like (or dislike) Queen Elizabeth.
