Celebrations and constitutional changes as a wave of royals came of age in 2023

A royal baby boom took place in 2005, and now all those royal babies are coming of age. Who has marked or is marking their 18th birthday this year?

Prince Hashem of Jordan

The youngest child of King Abdullah and Queen Rania turned 18 on 30 January (his father’s birthday). He is now attending university in the United States. He’s second in line to the Jordanian throne after his older brother, Crown Prince Hussein.

Countess Luana of Orange-Nassau

Luana was born on 26 March 2005 as the elder child of Prince Friso and Princess Mabel of the Netherlands. Although she is the granddaughter of the former Queen Beatrix, she is not in the line of succession as her father gave up his succession rights to marry her mother. Her uncle is the current King of the Netherlands, Willem-Alexander.

Princess Georiga (Gina) of Liechtenstein

Born on 23 July 2005, Gina is the second child of Prince Constantin and Princess Marie and the grandchild of Prince Hans Adam II.
