Tewodros's letter to Queen Victoria appealed to Christian solidarity in the face of the Islamic expansion occurring throughout the region but this garnered little sympathy. The British Empire's interests in Northeast Africa were not geared towards a Christian "crusade" against Islam but instead, the British sought to cooperate politically, strategically and commercially with the Ottoman Empire, Egypt and the Sudan. This was not only to protect the route to India but also to ensure that the Ottoman Empire continued to act as a buffer against Russia's plans for expansion into Central Asia. Moreover, as a result of the American Civil War, deliveries of cotton from the Confederate States of America to the British textile industry were declining, making the British increasingly dependent on Egyptian-Sudanese cotton. In the view of these interests, the British Foreign Office did not look favorably on supporting Tewodros. The letter was preserved but not answered.
