Princess Sisi, who is admired by many people in Austria, celebrated her 40th birthday on Christmas Day in 1877. Although she is the queen of Austria and Hungary and the wife of Emperor Franz Joseph I, she has no right to express herself, as long as she remains beautiful and young. To meet these expectations, she has been on a strict diet, fitness, hairdressing and measuring her waistline every day. These rules suffocated her, she longed for knowledge and life, did not want to just be a beautiful vase, so she began to break this image more and more frequently.
