Explanation:

Spain had a parliamentary system with a written constitution virtually continuously from 1833 until 1939. Spain has always been a monarchy, with the exception of the First Republic (1873–74), the Second Republic (1931–36), and the Spanish Civil War (1936–39). For a comprehensive list of Spain's regnant kings and Queens.

Political parties are recognised under the constitution as "the primary vehicles of political participation." The Political Parties Law of 1978 allocated public funds to them depending on the number of seats they had in parliament and the number of Votes they got.

Spain is categorised as a parliamentary monarchy, which is sometimes known as a democratic constitutional monarchy. As a result, the governing king serves mostly as a ceremonial head of state. Meanwhile, the national government is led by the democratically chosen Prime Minister. Spain comes up at number 22 on the Economist Intelligence Unit's Democracy Index for 2020.

Since La Transición, Spain's current political system has been in existence. After decades of military control by General Francisco Franco, the country transitioned from dictatorship to democracy under the former monarch, Juan Carlos I, in the late 1970s. The Spanish constitution was enacted in 1978 as part of this shift. The present national and regional political structures are built on this framework.
