MANILA, Philippines – In some European countries, kings and queens still rule.

Ten out of the 50 countries in Europe have hereditary monarchs as head of state: 5 kings, two queens, two princes, and a grand duke.

Among them, the oldest and longest-reigning is Queen Elizabeth II, 88, of the United Kingdom. She has been the queen for 62 years.

The youngest monarch is Spain’s King Felipe VI, 46, who took the Spanish throne on Thursday, June 19, following the abdication of his father, Juan Carlos. (READ: Spain’s new King Felipe VI takes oath in new reign)

Vatican City has the Pope, elected by the College of Cardinals to become the head of the Roman Catholic Church, as its monarch.

Meanwhile, Andorra is a constitutional diarchy, having the bishop of the Roman Catholic diocese of Urgell and the president of France as co-princes. – Rappler.com
