Modern Princesses Of Europe

Princess is the feminine form of prince (from Latin princeps, meaning principal citizen). Most often, the term has been used for the consort of a prince, or his daughters.
For many centuries, the title "princess" was not regularly used for a monarch's daughter, who might simply be called "Lady" or a non-English equivalent; Old English had no female equivalent to "prince", "earl", or any royal or noble aside from the queen, and the women of nobility bore the title of "Lady".
