The rise of modern Catalan nationalist sentiments dates from the last quarter of the nineteenth century. In essence, these sentiments reflected a growing political, intellectual and, to a lesser extent economic resentment within the region of Catalonia against the Restoration regime which was imposed upon Spain in 1875. The breakthrough of Catalan nationalism, or regionalism as it is sometimes called, to become a significant force in Spanish politics followed the victory of four Catalanist candidates in the elections to the Cortes of 1901. Shortly afterwards the groups responsible for that electoral success came together to establish what was, with the possible exception of the Socialists (P.S.O.E.), the first modern political party of Spain, the Lliga Regionalista. Significantly, the foundation of the Lliga marked a turning point in the nature of Catalan nationalism, or at least its dominant strain. Of the four candidates elected in 1901, all for Barcelona seats, three represented economic interests. Indeed, much more than that, they were, or had been, presidents of three of the most powerful big business organisations of the region.
