The first princess in Swedish history was changed to crown prince because she was born earlier than her younger brother (she was not crown prince when she was born-there are legal provisions and practices of male priority in the European system of succession to the throne, so far in Britain-only when there is no direct male heir, female heirs are considered). Her younger brother was made Crown Prince because he was a boy when he was born. But at that time, there was a call for equality between men and women in Sweden, and people demanded to establish heirs according to birth order rather than gender.
