Origin of the word "F.U.C.K."

In ancient England, people could not have sex without consent from the king. When people wanted to have a child, they had to solicit a permission to the monarchy. In turn they would supply a plaque to hang on their door when they had sex relations. The plaque read...Fornication under consent of the king (F.U.C.K). This is origin of the word (F.U.C.K.)!
