Princess
Most princesses in history got their title through marriage. Today we think of princesses as being born royal - being immediate members of a royal family.
Did you know for hundreds of years the title "princess" was not regularly used? A monarch's daughter was simply called "Lady". As women have slowly gained more autonomy, the title of princess is now seen as the female counterpart of prince. In some cases, a princess is the female hereditary head of state of a province in her own right.
