The Hispanic Monarchy (MonarquĂa HispĂĄnica in Spanish), also known as the Catholic Monarchy and historically referred to as the Monarchy of Spain, was the political entity encompassing the territories and dependencies of the Spanish Empire between 1479 and 1716. These regions maintained distinct, individual public institutions, councils, and legal systems, but were united under the control of a superior entity (the King of Spain) and common state institutional structures. This monarchy was administered under a polysynodial system of councils. The Spanish monarch acted as king (or with the corresponding title) according to the political constitution of each kingdom, state, or lordship, and thus, their formal power varied from one territory to another. However, they acted as a unified monarch over all the territories of the monarchy, almost like a Composite Monarchy.
The Monarchy included the Crown of Castileâwith Granada, Navarre and the kingdoms of the Indiesâand Aragonâwith Sicily, Naples, Sardinia, Malta and the State of the Presidiâ, Portugal and its overseas territories between 1580 and 1640, the territories of the Burgundian Circle except between 1598â1621âFranche-ComtĂ©, the Netherlands, as well as Charolaisâ, the Duchy of Milan, the Marquisate of Finale, the Spanish East Indies, and Spanish Africa.
