Juliet reflects the renaissance person in her character. She won't accept the status quo of her life's situation. This is true of the artistry, the building, and the music of the period.
Renaissance people are dramatic and impulsive. Juliet is ready to kill herself about 15 different times in the storyline of Romeo and Juliet. Sometimes you take a risk and it kills you, other times, the risk is the difference between mediocre and fantastic. Juliet worked so hard to go against her parents and that would not have been okay during that era. This rebellion marks her as a renaissance person.
During the Renaissance, a wealthy woman was expected to marry young, obey her husband and be loyal to him, and bear children, especially heirs. Like a young woman of her time, Juliet has a father who arranges the marriage to a young man of family and wealth. While other girls do not marry young because they must work for their families, fourteen is the normal age at which wealthy women are married. And, the father, like Lord Capulet, makes arrangements with a suitable young man, one who has a reputable name, position, and property. A dowry is paid to the new husband when the young couple are married.
Also, typically, Juliet is cared for by a wet nurse just as other young wealthy women of her time are. The Nurse is probably a poor relative who serves in the Capulet home for her room and board; her affection for Juliet seems to indicate that she is most likely related to the girl for whom she is so fond and proud.
