The Spanish Crown refers to the monarchy of Spain, which has a long and complex history dating back to the unification of the Kingdoms of Castile and Aragon in the late 15th century. The crown symbolizes the authority and governance of the Spanish state, with the current monarch being King Felipe VI, who ascended to the throne in 2014. The Spanish Crown plays a significant role in the country's political system, which is a parliamentary constitutional monarchy. While the monarch's powers are largely ceremonial, the crown represents national unity and continuity, and it is involved in various state functions and diplomatic activities.
