The subject which he seems to have been most deeply interested in was education, and his study focused in particular on physical education and the role of sport in schooling. In 1883, he visited England for the first time, and studied the program of physical education instituted under Thomas Arnold at the Rugby School. Coubertin credited these methods with leading to the expansion of British power during the 19th century and advocated their use in French institutions. The inclusion of physical education in the curriculum of French schools would become an ongoing pursuit and passion of Coubertin's.
