In 1813 Cuba, by the adoption of the constitution of 1812, became entitled to representation in the Spanish Cortes, and Arango was unanimously chosen for this office. There was no person in Cuban politics more fitted for the honor. He proved himself worthy, for, as deputy to the Cortes, he achieved the greatest victory of his long fight for the good of Cuba, the opening of Cuban ports to foreign trade. New honors awaited him, for he was awarded the Grand Cross of Isabella, and when in 1817 he returned to Cuba, he was accorded the rank of Counsellor of State, and Financial Intendente of Cuba. Arango died in 1837, having lived seventy-two years, and having faithfully served his country for the greater portion of them. He bequeathed a large portion of his considerable fortune for public purposes and charitable objects, all for the betterment of the land that he loved. In the darkest hours of tyranny, while suffering wrongs that would have inflamed other peoples to rebellion, Cuba remained "The Ever-Faithful Isle" for many years, until forced to rebellion. Against the background of injustice, as contrasted with the Spanish Captains-General who were to follow, and whose sole interest in Cuba was to extract as much as they could from her, acting on the principle of "after us the deluge," and caring nothing for her ultimate fate, the figure of Arango, the native Cuban, fighting at home and abroad for Cuba, stands out in bold and happy relief. It is not a matter for surprise that his name has been written on the annals of Cuba, with all the love and respect with which the other South American countries revere Bolivar. Here was a man who could not be tempted by honors, who refused remuneration for his services, and who against the greatest odds stood staunchly for everything which would help his travailing country.
