The injustice of illegal quartering during the Revolutionary War led to the passage of the Third Amendment to the Constitution which states that: "No Soldier shall, in time of peace be quartered in any house, without the consent of the Owner, nor in time of war, but in a manner to be prescribed by law."
Americans, still upset at the quartering of soldiers in their homes, wanted to ensure that future Americans would never have to endure the same again.
I don't understand what you mean by the term "middle kingdom." In the Tang Dynasty of China, they considered themselves to be the Middle Kingdom because they saw themselves as the center of the earth, if that helps.
