What amendent was the no quartering of soldiers in homes without the approval of the owner?

The amendment that prohibits the quartering of soldiers in private homes without the owner's consent is the Third Amendment to the United States Constitution. Ratified in 1791, it was a response to British practices during the American Revolutionary War, where soldiers could be housed in civilian homes against the residents' wishes. The Third Amendment reflects the Founding Fathers' emphasis on personal privacy and property rights.
