On the 1st March, 1821, Martinez de la Rosa was called on to form a ministry, which duty he finally undertook, though he had at first strenuously declined it. He had good reason to decline it, as the king himself was throughout that period plotting against his own ministers and government, to re-establish himself in absolute power. At the end of June, Martinez de la Rosa found himself under the necessity of tendering his resignation, and insisting upon its being accepted, though both the king and the council at first refused to do so. The moderate course which he wished to follow pleased neither party; and even he, who had suffered six years of unjust imprisonment in the popular cause, was now looked on as a traitor by the people, and ran great risk of being murdered in a public commotion raised in the city. Had he chosen to take a more decisive part, either on the one side or the other, the weight of his character would no doubt have given it the preponderance. As it was, the question was decided by the invasion of the French under the Duc d’Angoulême, who restored Ferdinand VII. to his former authority. When the French entered Spain, the constitutionalist government had retired to Seville; but Martinez de la Rosa had been obliged, from illness, to remain at Madrid. There being called upon to give in his adhesion to the authority imposed by foreign arms on the nation, he declined to do so, and thought himself fortunate in having no severer penalty to suffer thereupon, than to have his passport given him to go from Spain, while others had to suffer so much more severely. He then retired to Paris, where he resided eight years, paying occasional visits to Italy, and though not proscribed directly as an exile, yet he was not allowed to return to his country. During those eight years he devoted his leisure to literary pursuits, and composed most of those works on which his fame must permanently rest; such as his poem, ‘Arte Poetica;’ his very beautiful ‘Ode on the Death of the Duchess de Frias,’ and several plays; among them the ‘Tragedy of the Conspiracy of Venice,’ considered the best of all he had written. Thus occupied in endeavouring to make future generations wiser and better, Martinez de la Rosa gained increased respect at home with his increased reputation abroad; and on the moderating of the first angry party-feelings in Spain, was at the end of eight years allowed to return to Granada.
