Maria Christina of the Two Sicilies
The custom to name the head of government as "president" dates back to the reign of Isabella II, specifically to 1834 and the regency of Maria Christina of the Two Sicilies when, styled after the head of government of the French July Monarchy (1830), the official title was the ("President of the Council of Ministers"). This remained until 1939, when the Second Spanish Republic ended. Before 1834 the figure was known as ("Secretary of State"), a denomination used today for junior ministers.
