Catalan nationalism, under the leadership of Prat de la Riba, achieved in 1913 a victory in obtaining partial self-government for the "Commonwealth" (Catalan: "Mancomunitat"; Spanish: "Mancomunidad"), a grouping of the four Catalan provinces, presided over first by Prat de la Riba, and later by Josep Puig i Cadafalch; this was later suppressed in March 1925, during the 1923–1930 dictatorship of Miguel Primo de Rivera. The Commonwealth of Catalonia established a modern infrastructure, such as roads and telephones and expanded the culture (libraries, professional education, use and regulation of Catalan language, promotion of sciences...). In 1919 the Commonwealth promoted the first project of Statute of Autonomy, but the disagreements with the government of Madrid, the opposition of sectors of Spanish society and the coincidence with the rise of the workers movement provoked the fall of the project.
