Crown Princess Victoria of Sweden
When Crown Princess Victoria ascends to the Swedish throne, she will become the fourth female monarch in the country’s history. The eldest of King Carl XVI Gustaf and Queen Silvia, Victoria was born in July 1977, followed by Prince Carl Philip in May 1979, and Princess Madeleine three years later, in June 1982.

Interestingly, there was a period of time when she was not heir apparent, however. Her younger brother became heir to the Swedish throne upon his birth, a position he held for seven months. Everything changed in January 1980 when a change in constitution came into effect, which made the natural birth order the basis for succession. It was from this point forward that Victoria became the nation's future queen.
Princess Estelle of Sweden
Crown Princess Victoria will herself be succeeded by her own daughter, Princess Estelle. Victoria and her husband Prince Daniel were married in June 2010 and welcomed little Estelle on 23 February 2012. Their second child, Prince Oscar, was born on 2 March 2016.

Estelle will make history when she ascends to the throne. She will be the first female in Swedish history to be born with the right to inherit the crown that cannot be superseded by the birth of a male heir, as well as the first person in Swedish history to be born of a female heir apparent.
Princess Leonor of Spain
Princess Leonor is the heir presumptive to the Spanish throne as the eldest daughter of King Felipe VI and Queen Letizia. When she ascends to the throne, the 15-year-old will be the first queen regnant since Isabella II, who reigned from 1833 to 1868. Leonor has a younger sister, Infanta Sofia, who was born in April 2007.
Princess Leonor is now studying at UWC Atlantic College in Wales

"You must first get to know yourself through and through. That's what I am constantly emphasizing with Amalia," Willem-Alexander told Dutch author Wilfried de Jong. "I keep saying: know your own limits. Go everywhere. Make mistakes, as far as possible out of the eyes of the public. I did that, a lot. Festivals, parties, everything and more - find your boundaries. It is a good thing to do, without doing it in the public domain."
Amalia has two younger sisters: Princess Alexia and Princess Ariane.
Princess Elisabeth of Belgium
Princess Elisabeth became heir apparent to the Belgian throne in 2013, following the abdication of her grandfather, King Albert II. Elisabeth, 19, is the eldest child of King Philippe and Queen Mathilde, and has three younger siblings – Prince Gabriel, Prince Emmanuel, and Princess Eleonore.
