Silvela to his edition of the Cartas de Sor Maria de Agreda y del rey Felipe IV.
The task of reorganization was confided by the queen-regent to Seor Silvela, who had been universally recognized as the leader of the Conservatives and Catholics after the death of Canovas del Castillo.
Silvela endeavoured to unite in what he styled a Modern Conservative party the bulk of the followers of Canovas; the Ultramontanes, who were headed by General Polavieja and Seor Pidal; the Catalan Regionalists, whose leader, Duran y Bas, became a cabinet minister; and his own personal following, of whom the most prominent were the home secretary, Seor Dato, and the talented and energetic finance minister, Seor Villaverde, upon whose shoulders rested the heaviest part of the task of the new cabinet.
Silvela lacked the energy and decision which had been the characteristics of Canovas.
After parting with Villaverde, Silvela met with many difficulties, and had much trouble in maintaining discipline in the heterogeneous ranks of the Conservative party.
On the 6th of December a Conservative cabinet was formed under Seor Silvela, Seor Villaverde, pledged to a policy of retrenchment, taking the portfolio of finance.
The Republicans, under Salmeron, also had their troubles, of due to the growing influence of Socialism; and, finally, the Conservatives were distracted by the rivalries between Silvela, Villaverde and Maura.
A ministerial crisis followed; Maura resigned; and though the elections to the senate resulted in a large Conservative majority, and though in the lower house a vote of confidence was carried by 183 to 81, Silvela himself resigned shortly afterwards.
He did not object to some of his political friends, like Silvela and Elduayen, entering the cabinets of King Amadeus, and in 1872 declared that his attitude would depend on the concessions which government would make to Conservative principles.
After the war with America, and the loss of the colonies in 1899, when Senor Silvela formed a new Conservative party and cabinet, the old marshal accepted the presidency of the senate, though his health was failing fast.
