What happened April 1931 AD

Support for the Rivera regime gradually faded, and Miguel Primo de Rivera resigned in January 1930. He was replaced by General Dámaso Berenguer, who was in turn himself replaced by Admiral Juan Bautista Aznar-Cabañas; both men continued a policy of rule by decree. There was little support for the monarchy in the major cities. Consequently, King Alfonso XIII gave in to popular pressure for the establishment of a republic in 1931 and called municipal elections for 12 April of that year. The socialist and liberal republicans won almost all the provincial capitals, and following the resignation of Aznar's government, King Alfonso XIII fled the country.

At this time, the Second Spanish Republic was formed. It remained in power until the culmination of the Spanish Civil War.

On April 15, Luciano invited Masseria and two other associates to lunch in a Coney Island restaurant. After finishing their meal, the mobsters decided to play cards. At that point, according to mob legend, Luciano went to the bathroom. Four gunmen then walked into the dining room and shot and killed Masseria.
