How did Spain go from a monarchy to a republic?

The form of government in Spain is a parliamentary monarchy, that is, a social representative democratic constitutional monarchy in which the monarch is the head of state, while the prime minister—whose official title is "President of the Government"—is the head of government.

Explanation:

The Republic was proclaimed on 14 April 1931, after the deposition of Alfonso XIII, and it lost the Spanish Civil War on 1 April 1939 to the rebel faction that would establish a military dictatorship under the rule of Francisco Franco. The revolt was finally suppressed by the Republic with the intervention of the army.
