Traditionally Derby's ministries were thought in hindsight to have been dominated by Disraeli. However, recent research suggests that this was not always the case, especially in the government's conduct of foreign policy. There, Derby and his Foreign Secretaries, Lord Malmesbury and later his son Lord Stanley, pursued a course of action that was aimed at building up power through financial strength, seeking to avoid wars at all costs, co-operating with other powers, and working through the Concert of Europe to resolve diplomatic problems. This contrasted sharply with the policy of military strength and prestige that Disraeli would later pursue, and Derby's very different take on foreign policy could be seen as the precursor of "splendid isolation", as well as the diplomatic settlement of Europe pursued by later Conservatives in the late 19th century and the 1930s.
