Isabel II was now declared of age (1843), and from the date of her accession two political parties, the Progressists and the Moderates, under the leadership of Espartero and Narvaez respectively, contended for control, until, in 1865, the insurrection of Vicalváro gave the direction of affairs to O'Donnell, Canovas del Castillo, and others, who represented the liberal Unionist party. They remained in power till 1866, when Prim and Gonzales Bravo raised the standard of revolt once more and Isabel II was dethroned. Then another provisional government was formed under a triumvirate composed of Generals Prim, Serrano, and Topete, who represented the Progressist and the democratic parties (September, 1868). They steered the ship of state till 1871, and, seeing the rocks of revolution still ahead, offered the Spanish crown to Amadeo, who, after wearing it scarce two years, found it too heavy for his brow, and abdicated. He had changed ministeriums six times in less than two years, and came to the conclusion that the modern Spaniards were ungovernable. A republican form of government was now established (February 11, 1873), and it was understood by all parties that it should be a Federal Republic, in which each of the provinces should enjoy the largest possible amount of autonomy, subject to the authority of the central government. This proved to be the stumbling-block; the deputies could not agree on the details, passions were aroused, violent discussions took place. The Carlists, seeing a favorable opportunity, plunged the Basque provinces, Navarra, Cataluña, lower Aragón, and part of Castilla and Valencia, into civil war. At the same time, the Radicals promoted what were called "cantonnal" insurrections in Cartagena, and Spain seemed on the verge of social chaos and ruin. A _coup d'état_ saved the country. General Pavia, the Captain-General of Madrid, with a body of guards forced an entrance into the halls of congress and turned the Deputies out (January 3, 1874). A provisional government was once more constituted with Serrano at the head. His first act was to dissolve the Cortes. * * * * * The events just summarized exercised a baneful influence on the social, political, and economic conditions of this and of its more important sister Antilla. Royalists, Carlists, Liberals, Reformists, Unionists, Moderates, and men of other political parties disputed over the direction of the nation's affairs at the point of the sword, and as each party obtained an ephemeral victory it hastened to send its partizans to govern these islands. The new governors invariably proceeded at once to undo what their predecessors had wrought before them.
