Alfonso XIII of Spain in the context of "Reinosa"

The Provisional Government of the Second Spanish Republic (Spanish: Gobierno Provisional de la Segunda República Española) was the government that held political power in Spain from the fall of Alfonso XIII of Spain on 14 April 1931 and the proclamation of the Second Spanish Republic until the approval of the Spanish Constitution of 1931 on 9 December and the formation of the first regular government on 15 December. The King's departure created the need for a provisional government, whose first president was Niceto Alcalá Zamora, who presided until 1936, when Manuel Azaña took over. The new constitution established freedom of speech, freedom of association, extended voting privileges to women, allowed divorce, and stripped the Spanish nobility of their special legal status.

Spanish Renovation (Spanish: Renovación Española, RE) was a Spanish monarchist political party active during the Second Spanish Republic that advocated the restoration of Alfonso XIII of Spain, as opposed to Carlism. Associated with the Acción Española think-tank, the party was led by Antonio Goicoechea and José Calvo Sotelo. In 1937, during the course of the Spanish Civil War, it formally disappeared after Francisco Franco's merger of the variety of far-right organizations in the rebel zone into a single party.

General Miguel Primo de Rivera's dictatorship over Spain began with a coup on 13 September 1923 and ended with his resignation on 28 January 1930. It took place during the wider reign of King Alfonso XIII. In establishing his dictatorship, Primo de Rivera ousted the liberal government led by Prime Minister Manuel García Prieto and initially gained the support of King Alfonso XIII and the army. During the Military Directory (1923–1925), the dictatorship created the official party of the regime, the Unión Patriótica (UP). It also censored the Spanish press and worked to eliminate separatism in Catalonia. Under Primo de Rivera's dictatorship, Spain won the Rif War, where Spanish forces fought Riffian tribes in Morocco.

Primo de Rivera's dictatorship established the Civil Directory in 1925. During the Civil Directory, Primo de Rivera created the National Assembly, where Spanish corporations had their interests represented. The dictatorship formed good relationships with Italy and increased its interactions with countries in Latin America. It invested heavily in Spanish infrastructure, such as roads and railways, and expanded labour laws to assist nursing mothers in the workforce. Throughout the dictatorship, women became an increasing percentage of Spain's skilled labour. In 1929 an economic downturn occurred, and the value of the Spanish peseta fell. The army's grievances with Primo de Rivera grew, and seeing this, the King stopped supporting the dictatorship. Primo de Rivera resigned in 1930, ending his dictatorship, and General Dámaso Berenguer succeeded him before Spain's Second Republic was established in 1931.
