Princess is the female monarch, or wife of a ruler, or the daughter of a king, queen, prince, emperor, empress. In some cases, a princess is the female hereditary head of state of a province or other significant area in her own right. The ancient meaning applies in Europe still to the extent that a female commoner who marries a prince will almost always become a princess. In many of Europe's royal families, a king would grant his heirs actual or theoretical principalities to train them for future kingship. Many people thinking that "prince" and "princess" are titles reserved for the immediate family of a king or queen. In fact, most princesses in history were not immediate members of a royal family. Some fictional princesses: Cinderella, Snow White, Sleeping Beauty, Aurora, Rapunzel, The Little Mermaid. All little girls love to pretend that they are beautiful princesses. They dress up like princesses just for fun at home.
