[226] He wrote a detailed account of the safari in the book African Game Trails, recounting the excitement of the chase, the people he met, and the flora and fauna he collected in the name of science.[227]
After his safari, Roosevelt traveled north to embark on a tour of Europe. Stopping first in Egypt, he commented favorably on British rule of the region, giving his opinion that Egypt was not yet ready for independence.[228] He refused a meeting with the Pope due to a dispute over a group of Methodists active in Rome. He met with Emperor Franz Joseph of Austria-Hungary, Kaiser Wilhelm II of Germany, King George V of Great Britain, and other European leaders. In Oslo, Norway, Roosevelt delivered a speech calling for limitations on naval armaments, a strengthening of the Permanent Court of Arbitration, and the creation of a "League of Peace" among the world powers.[229] He also delivered the Romanes Lecture at Oxford, in which he denounced those who sought parallels between the evolution of animal life and the development of society.
