The municipal elections of 12 April 1931, the first to be held since the dictatorship, gave an ample victory to the left wing. On 14 April, Francesc Macià proclaimed the Catalan Republic from the Palau de la Generalitat. That same day, the Second Spanish Republic was proclaimed in Madrid. Under pressure from the provisional government of the Spanish Republic, Macià agreed to turn his proposal for a Catalan Republic into an autonomous governing body, the Generalitat de Catalunya. A Statute of Self-government, approved by a referendum amongst the people of Catalonia and by the Cortes of the Republic, defined the powers of the Catalan government.
