In the presidential campaign of 1876 Lowell was active, making speeches, serving as delegate to the Republican Convention, and later as Presidential Elector. There was even much talk of sending him to Congress. Through the friendly offices of Mr. Howells, who was in intimate personal relations with President Hayes, he was appointed Minister to Spain. This honor was the more gratifying to him because he had long been devoted to the Spanish literature and language, and he could now read his beloved Calderon with new joys. In 1880 he was promoted to the English mission, and during the next four years represented his country at the Court of St. James in a manner that raised him to the highest point of honor and esteem in both nations. His career in England was an extraordinary, in most respects an unparalleled success. He was our first official representative to win completely the heart of the English people, and a great part of his permanent achievement was to establish more cordial relations between the two countries. His literary reputation had prepared the ground for his personal popularity. He was greeted as “His Excellency the Ambassador of American Literature to the Court of Shakespeare.” His fascinating personality won friends in every circle of society. Queen Victoria declared that during her long reign no ambassador had created so much interest or won so much regard. He had already been honored by degrees from Oxford and Cambridge, and now many similar honors were thrust upon him. He was acknowledged to be the best after-dinner speaker in England, and no one was called upon so often for addresses at dedications, the unveiling of tablets, and other civic occasions. It is not strange that he became attached to England with an increasing affection, but there was no diminution of his intense Americanism. His celebrated Birmingham address on Democracy is yet our clearest and noblest exposition of American political principles and ideals.
With the inauguration of Cleveland in 1885 Lowell’s official residence in England came to an end. He returned to America and for a time lived with his daughter at Deerfoot Farm. Mrs. Lowell had died in England, and he could not carry his sorrow back to Elmwood alone. He now leisurely occupied himself with literary work, making an occasional address upon literature or politics, which was always distinguished by grace and dignity of style and richness of thought.
