When James Bryce presented his credentials as ambassador from Great Britain to President Theodore Roosevelt in 1907, he probably knew more about the nation to which he had been sent than any foreign envoy in Washington before or since. He had made seven trips to the United States, the first in 1870, thirty-seven years before; he had visited every state from coast to coast; he had studied the federal constitutions and those of all the states; he had made himself an expert on Congress, on the state legislatures, on the judiciary, and on the party system; and he had extensively interviewed hundreds of American citizens. His classic work, The American Commonwealth, had been first published in 1888 and thereafter reissued again and again to thousands of readers on both sides of the Atlantic. Bryce was considered an expert on American affairs even in the United States, and his work was taught in schools and colleges here until it was finally out of date. His friend, Theodore Roosevelt, felt about him as did his sovereign, Queen Victoria, whom he once had accompanied on an Italian vacation as minister in attendance.
