The decadence of Primo de Rivera´s dictatorship

Yesterday, January 28, the fall of the dictatorship of Miguel Primo de Ribera took place
The dictator presented his resignation to the King of Spain Alfonso XIII and he accepted it, giving way to the "Dictablanda" of General Berenguer. The end of the dictatorship is the culmination of a process that began several months before.
His resignation is due to the fact that the social and political sectors that had initially lent their support to the Dictatorship - forming the "alliance of 1923 were withdrawn: the peripheral nationalisms when the dictatorship broke the promise of" decentralization "and ended up dissolving the Mancomunitat de Catalunya ; business organizations dissatisfied with the increase of the UGT's influence in labor relations - "the UGT strengthened their organizations and began to extend them to agriculture, which subverted the traditional relations between day laborers and employers in the campolos; intellectual and university sectors that abandoned their "benevolent expectation", disappointed with their conservative "regenerationism"; various social and political liberal groups that saw how the Dictatorship intended to perpetuate itself in power, breaking its promise to be a "temporary regime"; etc
