The Spanish monarchy is a constitutional monarchy, meaning that the monarch's powers are limited by a constitution. The current king is King Felipe VI, who ascended to the throne in 2014 after the abdication of his father, King Juan Carlos I. The monarchy plays a ceremonial role in the government, representing Spain at official events and promoting national unity. The Spanish monarchy has a long history, dating back to the unification of the Kingdoms of Castile and Aragon in the late 15th century. It has seen various changes, including the establishment of a republic and periods of dictatorship. Today, the monarchy is supported by many Spaniards, although it also faces criticism and calls for reform.
